Niobium Alloy Round Bars for High-Temperature Aerospace, Nuclear and Chemical Use

Shaanxi Chuanghui Daye Metal Material Co., Ltd. works out of Baoji, Shaanxi Province, China. The company supplies niobium alloy round bars there. Grades include Nb-1Zr and C-103. Niobium-tantalum and pure niobium are also available. These bars often go into aerospace parts. Nuclear equipment uses them as well. So does chemical equipment that runs at high temperatures. Purity is 99.9% or 99.95%. Cutting and surface finishing match your drawings. Diameters and lengths do too. If you need chemical composition data or material test reports, the company can provide them. The bars have good ductility. That means they can be formed or machined into fasteners, electrodes, and other custom parts.

What Are bars?

A refractory metal mill product, that is what This product is. Niobium gets alloyed with zirconium (Nb-1Zr) to make one. Hafnium and titanium (C-103) are another way to go, or tantalum on its own.

Tungsten melts at a high temperature too. Molybdenum does as well. Both are heavier than niobium alloys and more brittle. With niobium alloys you get a lighter option, and ductility stays good even at low temperatures. Liquid alkali metals have a hard time attacking them either, lithium and sodium included.

Specifications

The table lists only the data supplied for this product. Items without supplied data are marked as not specified.

Check the diameter and length with the supplier before ordering. Tolerance counts as well. Surface finish is another thing to ask about. Ask which standards apply too.

Alloy Grades and Purity Options

• Nb-1Zr: At high temperatures this alloy holds more tensile strength than pure niobium, and it resists creep better too. Reaction vessels are a common use. So are nuclear applications.
• C-103 (hafnium and titanium): This grade ends up in aerospace propulsion hardware. Thruster nozzle parts are one example. Afterburner parts are another.
• Niobium-tantalum alloy: Some designs need tantalum in the mix. This alloy can serve those designs. Include the exact composition you need in your inquiry.
• Pure niobium, 99.9% and 99.95%: This metal is ductile. Because of that, forming and machining get easier.

Key Advantages

High melting point. Pure niobium melts at roughly 2,477 °C. That is why vacuum furnaces and other hot equipment can use it. Heat it in air, though, and it oxidizes fast. A vacuum, an inert atmosphere, or another suitable safeguard is needed for this kind of work.

Corrosion resistance. Niobium stands up to a long list of acids. Hydrochloric and sulfuric acid are two of them, as long as the conditions are right. For chemical processing equipment, that makes these bars a practical pick.

Formability and machinability. Pure niobium bends without cracking, so ductility is not a problem. Different shapes are easy to form. Machining works too. Fasteners and electrodes are common products. Other parts that fit your application come out of it as well.

Applications

Some sectors cannot rely on common steels. Heat is one reason. Corrosion and liquid alkali metals are others. This product are built for those jobs.

• Aerospace and defense propulsion: Rocket thruster nozzles use C-103 parts. Jet engine afterburners use them too. Heavy thermal shock and vibration hit both of those.
• Nuclear engineering: Liquid lithium and sodium turn up in nuclear work. Nb-1Zr sees use there as well.
• Chemical processing: Hydrochloric and sulfuric acids reach some reaction vessels and other equipment. Where conditions suit it, Nb-1Zr handles those spots.
• High-temperature furnaces: Vacuum furnace systems need certain parts, and this alloy goes into them.
• Fasteners and electrodes: Parts machined directly from the bars.

The company's wider product range also serves the metallurgy, electronics, medical and special steel fields.

FAQ

Q: How does pure niobium differ from Nb-1Zr?

A: At high heat, Nb-1Zr keeps more of its tensile strength. Its creep resistance holds up better too. Reaction vessels and nuclear work suit it well for that reason.

Q: Can niobium alloy rods be soldered with common methods?

A: No. Heat niobium in air and it oxidizes fast. Lead-tin solder won't bond. TIG welding is one option. It needs a strictly controlled argon chamber. Electron beam (EB) welding is the other option.

Q: What surface finishes can I get?

A: Parts get finished to the spec you give us. The oxides come off once a surface is polished or ground. For industrial jobs, acid pickling tends to work fine. Black oxide coating does too. When the inquiry comes in, just state the finish you need.

Q: Can the bars be anodized for color?

A: Yes. Clean the surface well and pickle it correctly, and a layer forms on niobium alloy through anodic reaction. Teal, magenta, gold and blue are the shades you can get. No dyes are used at any stage.

Q: What purity grades can you supply, and what paperwork comes with them?

A: Our stock holds two grades: 99.9% and 99.95%. Want the chemical composition and material test reports? Ask us and we will send them across.

Q: Can you produce custom this product?

A: Yes. Your specs guide us. Diameter and length come from you. Cutting and surface finish work the same way. With your inquiry, include the drawing and the quantity you need.
