Tianium Alloy 6Al-2Sn-4Zr-6Mo Round Bar is used to machine high-strength parts that must hold their properties under heat, load, and corrosive exposure. Engineers specify it for aerospace compressor parts, industrial gas turbine rotors and casings, military hardware, chemical processing equipment, and marine hardware. Known as Ti-6246 or Ti-6-2-4-6, the alloy combines a density of 4.54 g/cm³ with a minimum tensile strength of 1030 MPa in CXMET material. This guide explains the bar's function, compares it with other materials, and shows how to buy it with the right documents.

What Is Titanium 6Al-2Sn-4Zr-6Mo Round Bar?

Alloy Composition and Naming

Titanium 6246, Ti-6-2-4-6, and Ti-6246 are all steels in the same group. It contains aluminum (6%), tin (2%), zirconium (4%), and molybdenum (6%). These are some of the main things that make it up. Every part does something. Tin and aluminum are added to the metal to strengthen it. The metal doesn't creep when zirconium is present, and molybdenum makes it easier to harden. This means that heat treatment works better on thick pieces. This alloy is used to make a solid cylinder that can be cut, forged, or worked on further. A Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar is what it's called. I tell my customers to be sure they know the exact grade, product form, heat treatment, and ruling standard before they place an order. This is because specs change all the time.

How CXMET Produces the Bar?

This Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar is made by Shaanxi CXMET Technology Co., Ltd. They use vacuum arc melted (VAR) or triple-melted chunks and then hot roll them into round bars. They have a 50,000-square-meter building in Shaanxi Province's "China Titanium Valley" where they run their business. It first opened in 2005. Many people work with metals like tin, nickel, tantalum, niobium, tungsten, molybdenum, zirconium, and different mixes of these. When you want parts made of stressed titanium that can't have any flaws, you need to melt them a lot. You have to heat it repeatedly to stabilize the chemicals, and our inspectors check it before shipping.

Product Snapshot for Engineers

Here is what you need to know about our bar. Sizes range from 6 mm to 200 mm, or 0.24 in. to 7.9 in. We can cut them to any length you want, up to 19.7 feet (6000 mm). Things like AMS 4981, ASTM B348, and MIL-T-9047 are on the list. The strength must be at least 1030 MPa in tension and at least 965 MPa in yield. It must also be able to stretch at least 10%. If you like, you can choose to age, anneal, or solution treat the metal. Even though these numbers are helpful, the official mill test record for each setting is what gives the go-ahead.

Key Properties of 6Al-2Sn-4Zr-6Mo Titanium Round Bar

Strength and Density

Titanium is at the top because it has a high specific strength. This ratio shows how strong it is compared to how much it weighs. This metal is a lot lighter than stainless steel, which weighs about 7.9 g/cm³. Our Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar is still in stock. It can be pulled apart at least 1030 MPa. Much of the information out there about old that has been fixed talks about pressures between 1,170 and 1,310 MPa. But the answer depends on the size of the piece and what you need. The supports and joints don't have to work as hard when there is less weight. Verify to see if the strength level on your order matches the rule you gave.

High-Temperature and Creep Behavior

Based on what we know about the product, the metal can stay in shape up to 550°C (1022°F). Zinc and tin help it stay in place even when it's hot and under a steady load. When something changes shape slowly, it's called creep. Titanium shouldn't oxidize either, since air on the surface can weaken it over time. As engineers build something, they should still check each part's stress, exposure time, and weather to make sure it doesn't break. Heat treaters set solution temperatures just below that point, which is almost 940°C (1725°F).

Corrosion Resistance and Fabrication

Titanium protects itself from seawater, acidic gases, and many industrial oxidants by forming a stable oxide film. Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar hardware can be used in acid plants and in the ocean. Galvanic contact lets us come into contact with hot chlorides, hydrogen, and other metals. We still need to look at each case. Making things also takes care. It's not as straightforward to work with as Ti-6Al-4V. Because it has more shear strength and work hardening, cutting speeds often slow down by 20 to 30 percent. You can weld with an electron beam if you do a few things right. Please give these enough time.

What Is Titanium 6Al-2Sn-4Zr-6Mo Round Bar Used For?

Aerospace and Gas Turbine Components

This metal is mostly used in space applications. People who work in machine shops use the Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar to make airplane disks, spools, blades, and bolts. It is used for blades and frames of industrial gas engines that need to be resistant to creep. In the middle stages of compressors, metal is often a good choice because it is strong where Ti-6Al-4V would bend or grow. If you forge or machine a part with a thick cross section, deep hardenability can also help. Some engine parts don't work well with metal, so the designer has to be okay with how each part works.

Oil and Gas, Chemical Processing, and Marine Hardware

In bad conditions, heavy drill stems, downhole tools, and tool housings can all cause stress cracks. Because it has molybdenum in it and the heat process is managed, it can be used in these places. Certain groups, such as NACE MR0175/ISO 15156, specify how hard something can be set. It is important that you follow the rules in the revision that your contract says you have to use. Chemical firms use the bar to guard tools that are used with acids and high temperatures. It's used to make hardware that resists heat and weight, doesn't rust, and lasts longer. Before you start making the product, make sure you and your supplier agree on its hardness and testing method.

Military, Power, and High-Tech Manufacturing

The military uses the bar to make gear that works well and parts of weapons that need to be strong but light. Teams made of iron and steel can test it to see if it can be used in places that are hot and stressed, and other metals won't work because they will creep. It is possible to use the alloy in both vacuum and inert atmospheres. This means that engineers who work on electronics, coating, and vacuum equipment can use the same properties to find structural parts. For race teams that need to be able to handle shock loads, it is also used in engine shafts. When someone buys metal, they should not only look at its name, but also test it and get OK to make sure it fits.

How Does Titanium 6246 Compare With Alternative Materials?

Compared with Ti-6Al-4V

Titanium metal, Ti-6Al-4V, is something most people have heard of. It costs less and ships faster most of the time. At 4.43 g/cm³, it's about as dense as Ti-6246. Parts that are thicker and warmer show the change. Ti-6246 is strong where Ti-6Al-4V is weak. It has a high strength that is more even across big cross sections. It is easy for Ti-6Al-4V to work at normal temperatures and loads. Ti-6Al-4V can't harden through thick pieces, hot parts, or parts that are under a lot of stress. Instead, use a Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar.

Compared with Ti-6242

Ti-62242 is better for high temperatures because it doesn't move as much. Ti-6246 is the best because it stiffens better when cut into bigger pieces and can pull apart more quickly. Study after study has indicated that Ti-6246 is better at resisting low-cycle fatigue. This is why one metal is called "alloy," and the other is also called "alloy." They have to agree to the move before you can do it. Don't use a Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar instead of Ti-6242 just to save time. Don't do what the drawing says. Please remember to have the pro check the temperature, stress, and license state of the service first.

Compared With Stainless Steel

There are many providers; you pay less up front, and it's simple to work with them. Titanium is lighter than steel. Steel weighs about 7.9 g/cm³, while Ti-6246 weighs only 4.54 g/cm³, which is about 40% less dense. It also stops chloride pits from forming in seawater better than many types of stainless steel. These traits are important for moving parts, airplane tools, and boat parts. When you compare prices, don't just look at the price on the bar. It's heavier, lasts longer in acidic media, and needs fewer fixes, but it costs more and cuts more slowly.

How to Choose and Buy 6Al-2Sn-4Zr-6Mo Titanium Round Bar?

Specifications and Quality Documents

To begin, look at what is normal. This bar is on CXMET's list under AMS 4981, ASTM B348, and MIL-T-9047. What form, size, and use the thing has will help you choose the right one. Ask for an EN 10204 3.1 mill test certificate that shows how the material was heated, tested chemically, stretched, and hit, and its heat number. Many people buy things that are also tested for metallography, AMS-STD-2154, or tension at high temperatures. Bad things inside the part, like hard alpha particles, can cause cracks to appear. The moving parts are safe because of these checks. Put each test on paper in the order that it will be given.

Avoiding Procurement Risks

People have the most trouble when they buy Ti-6246 instead of Ti-6242 or Ti-6Al-4V, accept certificates that aren't complete, order the wrong diameter or condition, or only look at price. The quote, the buy order, the packing list, and the barcode should all have the grade written on them. You should include the grade, standard, diameter, length, number, condition, tolerances, finish, inspection level, location, schedule, and tolerances in your full request. That way, you can compare how much it costs to land everything, such as taxes, freight, inspection, scrap, and machine work. Lots don't get turned down, lost, or held up in production because of these steps.

Conclusion

Around 550°C, the Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar made of Ti-6246 is used in places that need something strong, light, and secure. Tensile strength of at least 1030 MPa is possible with this bar. It weighs 4.54 g/cm³ and doesn't rust or creep. It is used in gas turbines, air compressors, harsh oil and gas tools, chemical machinery, and parts for ships. When you compare, you can see the good and bad points. While Ti-6Al-4V is cheaper, Ti-6242 doesn't spread as much at high temperatures, and stainless steel is lighter but costs more. Extra care needs to be taken when cutting and soldering. The best thing that can happen is for the buyer to set the standard, test, record, and heat treat the item, and then check the grade at each step.

FAQ

How does Ti-6246 differ from Ti-6242?

At high temperatures, Ti-6242 stops sliding better than Ti-6246. Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar is harder to make in large pieces when it comes to short-term tensile strength.

Can this alloy be welded?

It's difficult to weld because it can break over time. E-beam welders have to follow strict rules, but it's harder to join this metal than Ti-6Al-4V.

What heat treatment gives maximum strength?

To treat the area below the beta transus, most suppliers use a solution. They then let it cool in oil or air, and after 8 hours, they age it at 595°C. Make sure the cycle works for each order of Titanium Alloy 6Al-2Sn-4Zr-6Mo Round Bar.
