Tantalum Niobium Alloy Wire R05240 (Ta-40Nb) for Acid-Resistant Welding and Medical Use

R05240 (Ta-40Nb) wire for acid-resistant welding comes from Shaanxi Chuanghui Daye Metal Material Co., Ltd. This Tantalum Niobium Alloy Wire is made to ASTM B365. Diameters run from 0.3 mm to 3 mm. Purity is ≥99.9% or 99.95%. Tantalum brings the acid resistance. Niobium brings lower density and lower cost. Chemical processing, medical, aerospace and defense buyers all use it. The plant sits in Baoji High-tech Development Zone, Shaanxi Province. Customers in more than 50 countries buy from the company, and that includes the United States and Germany.

Why Choose Ta-40Nb

Ta-40Nb holds tantalum (Ta) and niobium (Nb). The two metals sit in a solid solution together. Cost and weight land somewhere between pure tantalum and pure niobium. Density comes in at approx. 12.1 g/cm³. Pure tantalum weighs far more, at 16.6 g/cm³. Price or weight often rules pure tantalum out. When that happens and you still need the corrosion resistance, take a look at this product.

Hot concentrated mineral acids can eat into stainless steels. So people often consider tantalum-based materials for that duty. Hydrofluoric acid (HF) is the exception. That one should be avoided.

Specifications

This page leaves out a few details. Mechanical properties and length are not listed. Packaging is not shown either. MOQ and lead time are missing too. When you send your inquiry, ask the supplier to confirm these.

Certification

Properties and Handling

The wire is meant for service in sulfuric acid. Hydrochloric acid is part of that service too. Organic compounds are also covered. This page names no other use. Corrosion-rate data is absent from this page. Before you order, check with the supplier. Make sure the wire fits your medium, your concentration and your temperature.

Fine diameters are within reach in Ta-40Nb through cold working. Yield strength and elongation both move when oxygen is present. Nitrogen has the same effect. Carbon and hydrogen do too. Interstitial impurities stay under control for that reason. The specification lists them for the same reason.

In air, hold the wire below 250 °C. If that is not possible, shield it. Oxidation and embrittlement are the risk otherwise.

Applications

Chemical processing. This wire is used to build and repair tantalum-lined equipment. Heat exchangers are one place it shows up. Bayonet heaters count too. It also works as welding filler. Hot concentrated sulfuric or hydrochloric acid service is what these tantalum sheets and clad vessels are built for. Before production begins, qualify your welding procedure. Run test sample joints as well.

Medical devices. Pacemaker leads are one place where Ta-40Nb wire gets looked at. Surgical clips and suture wires are two more. On these parts, biocompatibility matters. So does X-ray visibility, along with low magnetic response. Tell us the standard a medical part must meet when you request this product. Implant approval is not claimed on this page.

Aerospace and defense. Pure tantalum is denser than this material. In this field, weight matters. That fact counts too. Rules for qualification change from one program to the next. Talk to us before you order. We will check them for you.

Inspection and Documentation

Find out which inspection items and test records ship with your order. Buyers usually review these things:

Chemical composition: check the Ta/Nb ratio. The interstitial impurities count too (O, N, H, C).
Mechanical properties: tensile strength and yield strength both matter. Elongation sits in the same group. Winding or weaving is the step where these values count most.
Surface condition: splits, die marks, inclusions. Corrosion cracking can start from any one of them.
Dimensions: automated welding and medical assembly both need the diameter to hold steady.

The spec table lists impurities below 500 ppm. Diameter uniformity shows up there too, usually ±1% or tighter. Get the tolerance for your order confirmed in writing.

Surface Finish and Welding of Tantalum Niobium Alloy Wire

The wire we ship comes acid washed (chemically cleaned) or electropolished. Both finishes remove drawing lubricants and surface oxides. Clean welds get easier that way.

People use Ta-40Nb together with tantalum and niobium. If a joint involves another refractory metal, titanium or zirconium for example, carry out a procedure qualification test first, before production starts.

Ordering Information

Any diameter between 0.3 mm and 3 mm works. Choose purity of ≥99.9% or 99.95%, depending on what your application needs. State the quantity in your inquiry. Include the surface finish you want. List the standards you require. Note any medical specification. This page does not list lead time. MOQ, packaging, and certificates are missing too. Ask about all of them together.

About the Supplier

Baoji High-tech Development Zone in Shaanxi Province is where Shaanxi Chuanghui Daye Metal Material Co., Ltd. is based. Locals call this part of China "Titanium Capital". Titanium counts among the metals made by the company. Production covers tantalum too, and niobium is a third. Tungsten sits in the range. For molybdenum, the company handles it as well. Zirconium appears in the lineup. Nickel is another metal they work with. Other non-ferrous products are included. Rare metal alloy products form part of the range. Metallurgy buyers come to them. Electronics customers do too. Medical work is another market. The special steel field buys from them as well. In the rare metal industry, the founder has spent over 30 years. More than 50 countries have received their products. The United States is one market. Germany, South Korea, and Singapore are others. We also supply the Tantalum Niobium Alloy Wire in custom sizes to suit your drawing.

FAQ

Q: What is Ta-40Nb wire?

A: This wire is a solid-solution alloy. Tantalum and niobium are the metals in it. Grade R05240 applies. Production follows ASTM B365.

Q: How is it different from pure tantalum?

A: The listed density is approx. 12.1 g/cm³ versus 16.6 g/cm³ for pure tantalum. It costs less than pure tantalum too. For acid resistance, it is meant to work like tantalum, except in HF. Run a test in your own medium.

Q: Can you use it in air at high temperature?

A: Shield the wire when it sits in air. Holding the heat below 250 °C works too. Do neither and it oxidizes, then turns brittle.

Q: What surface finishes can I get?

A: Acid washed or electropolished.

Q: Is it suitable for medical use?

A: It comes down to your device and the standard you work to. Tell us your medical spec, then we can talk over whether our this product fits it.
