Tungsten alloy Description and Application:

High specific gravity alloy Tungsten wire is a kind of the base of tungsten (W content of 85-99%), and added with Ni, Cu, Co, Mo, Cr and other elements of the alloy. Characteristics and uses according to the alloy composition into W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag other major series, a high density of 16 .5-19.0g/cm3, and by the world known as the high proportion alloy, it also has a series of excellent features, heavy: Average specific gravity of 16.5-18.75g/cm3,, high strength: tensile strength of 700-1000Mpa, absorb radiation capability: its capacity than 30-40% of lead high thermal conductivity coefficient: 5 times to die steel; thermal expansion coefficient: Only 1/2-1/3 of iron or steel, good conductive properties; has good weldability and workability . Given the high proportion alloy has the excellent features, it is widely used in aerospace, aviation, military, oil drilling, electrical instrumentation, medical and other workers.
