MATERIAL PROFILE

Tantalum-2.5% Tungsten (Ta-2.5W) Wire

Ta-2.5W alloy wire
Ta-2.5W alloy wire measured with a vernier caliper

Ta-2.5W wire offers excellent corrosion resistance, heat resistance, mechanical strength, and machinability. Various mechanical properties and processing conditions can be achieved through cold working and heat treatment. The material is suitable for corrosive environments, high-temperature environments, and industrial applications requiring high material reliability.

Products can be manufactured in accordance with relevant standards, such as ASTM B365 R05252, and material test reports and quality certificates—including chemical composition and mechanical properties—are provided.

Ta-2.5W wire is available in various diameters, lengths, and coil weights, as well as under various delivery conditions, in accordance with customer requirements. Annealing, cold working, or other custom-made conditions are available upon request.

Ta-2.5W wire in various diameters and lengths can be supplied according to customer specifications. We can manufacture products to individual specifications based on technical characteristics and application requirements, as well as provide custom annealing, cold working, and processing conditions.
