Measuring the Diameter of Ta-10%W Tantalum Wire with a Vernier Caliper

Ta-10W tantalum-tungsten alloy wire, grade R05255. Ta-10W wire is suitable for manufacturing springs and elastic components operating in high-temperature, highly corrosive, and specialized environments. In the ASTM B365 standard, R05255 is specified as tantalum wire consisting of 90% tantalum and 10% tungsten.

Ta-10W spring wire offers excellent corrosion resistance and good mechanical stability at high temperatures, making it suitable for the manufacture of compression springs, tension springs, torsion springs, leaf springs, and other custom-made elastic components.

Ta-10W wire is particularly suitable for applications requiring high high-temperature strength, corrosion resistance, dimensional stability, and reliability.

In chemical processing equipment, Ta-10W springs can be used in valves, control mechanisms, and sealing systems in corrosive environments; In vacuum furnaces, semiconductor, and aerospace equipment, they can be used in high-temperature clamping mechanisms, relief mechanisms, and flexible connecting elements.

The products are available in a variety of diameters, lengths, conditions, and surface finishes to meet customer requirements and can be supplied in coils, spools, or as straight wire in fixed lengths.
