Tantalum Metal and Alloys
Hard-to-Resist Tantalum Metal Materials
Tantalum metal is a heat-tolerant and refractory with excellent corrosion resistance similar to niobium. Often alloyed with other metals, tantalum is an exotic metal used to make superalloys.
Common applications of exotic tantalum metal include chemical processing, jet engines, and nuclear reactors. The oxidation properties of tantalum metal also make it an excellent choice for many electronic applications, including electrolytic capacitors and high-power resistors. It is also highly bio-compatible and used extensively for medical applications, such as skull plates, hip joints, suture clips, and stents.
Tantalum metal products (pure and with 2.5% tungsten) are typically produced using an electron beam melt followed by a vacuum arc remelt. Ingots are then processed by forging and then rolling, drawing, or extrusion to provide foil, sheet, plate, or rod/bar. Tubing is also available upon request.
What you need to know about buying Tantalum metal foil, strip, sheet, plate and rod/bar
- Tantalum metal rod/bar products are produced to ASTM B365 with foil (less than 0.005”), sheet (0.005” to 0.187”), and plate (over 0.187”) products produced to ASTM B708. Strip products can be supplied in coil and are usually less than 6” in width but can be supplied up to 12” in width. Tantalum products are available in the following alloys:
- R05200 – Unalloyed tantalum – electron beam or vacuum-arc melt, or both
- R05252 – Tantalum alloy, 97.5% tantalum, 2.5% tungsten
- All tolerances are per applicable specifications except for tantalum foil, which would be agreed on with the customer.
- Surface condition (as rolled, buffed, ground) should be supplied with each inquiry.
- Material is supplied in the annealed condition unless specified.
- We can provide ,machined and fabricated parts made from tantalum metal with supplied drawings.
