Tantalum Round Bar

Tantalum Round Bar for Machined Fasteners, Electrodes and Vacuum Parts: Custom Sizes and Grades from CHDY

Tantalum is a ductile refractory metal. It resists corrosion and has a very high melting point. CHDY supplies Tantalum Round Bar as starting material for machined cylindrical parts. The same stock goes into fasteners and electrodes. Vacuum equipment components are another use. Bars come in different sizes. Grade options include R05200 and R05400 pure tantalum. R05252, R05255 and R05240 alloys are available too. Shaanxi Chuanghui Daye Metal Material Co., Ltd. is based in Baoji High-tech Development Zone. Customers in more than 50 countries have received its products, including the United States and Germany.

Overview

The symbol for tantalum is Ta, and its atomic number is 73. This group 5 metal is hard and lustrous, with a blue-gray color. In nature it appears with niobium in tantalite, columbite and coltan. Labs and industrial plants often pick it because it does not react chemically.

Tantalum bar is commonly bought as starting material for machining. It can be turned into cylindrical components, fasteners, electrodes, and specialized industrial parts.

Tantalum Grades

The grade information below is for reference. Confirm the grade and available material details with CHDY before placing an order.

Sintered R05400 is fine-grained and comes from powder metallurgy. Melted R05200 fits projects that need electron-beam or vacuum-arc melted stock.

Selecting Tantalum Round Bar for Machining

When you pick This product for machining, size alone won't tell you the whole story. Go through the points below against your drawing before you ask for a quote.

• Machining allowance: There has to be enough stock on the starting diameter to reach the finished part. How much you leave depends on the final dimensions and your machining process, plus the surface condition.
• Material condition: Tantalum is fairly ductile. Under the tool it can act quite differently from the metals most engineers are used to. Cutting performance and the final surface quality can both shift with condition.
• Straightness: Precision parts and long bars call for a close eye on straightness. Tell us about any special requirement before you place the order.
• Surface quality: Machining results can suffer from surface defects and differences in dimensions. Where the application is critical, settle the surface requirements with CHDY up front.

Material Properties That Matter in Service

Most acids do not attack tantalum. Two that do are hydrofluoric acid and hot sulfuric acid. Hot alkaline solutions will corrode it as well. Check what your process media contains before you pick it.

This metal has a high melting point. It resists oxidation well. Density is high as well. It is not magnetic, and it is bio-inert. One use is as an orthopedic material.

Be used in a wide range of industries.

Typical Applications

• Machined chemical equipment parts: reaction vessel components, valve bodies, thermowells, and parts for corrosive liquids.
• Tantalum fasteners: bolts and similar parts for corrosive service.
• Industrial electrodes: machined from solid bar.
• Vacuum equipment components: including heating rods for vacuum furnaces.
• Research components: laboratory parts, in some cases replacing platinum.
• Special cylindrical parts: we build them to your drawing.

Related tantalum parts include crucibles, and rare earth smelting is one job they do. PVD evaporation coating is another use. Chemical synthesis uses them too.

Purchasing Considerations

Tantalum is a rare metal. Getting it out of the ground is not simple. It costs more than common metals, and supply can take a while. So set your lead time early.

People sometimes call tantalum a conflict metal. Ask where the material comes from. Before you order, talk through the documents your project needs.

FAQ

Q: What is this product used for?

A: It is machined into fasteners, electrodes, vacuum equipment parts, chemical equipment components, and research parts.

Q: Which grades can I order?

A: You can pick from R05200, R05400, R05252, R05255 or R05240. First check which grade your drawing calls for.

Q: Does acid affect tantalum?

A: Most acids leave tantalum alone. Hydrofluoric acid will attack it, though. So will hot sulfuric acid, and so will hot alkaline solutions.

Q: What do I need to check before machining starts?

A: Look at the machining allowance and the material condition. Straightness matters too, and so does surface quality. Cutting behavior can shift because tantalum is ductile.

Q: Can I order custom sizes?

A: Yes. Sizes and grades vary, and CHDY supplies them to match what each customer asks for.

Q: What should I send for a quote?

A: Tell us the grade and the diameter. Add the length and the quantity. If you need a set straightness or a surface finish, include that as well.
