This is a kind of matrix with W-based Alloy (W content of 85-99%), and add there is Ni, Cu, Co, Mo, Cr and other alloy elements. By alloy composition characteristics and uses are divided into W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag and other major series, and its density up to 16 .5-19.0g/cm3, were the world known as the high proportion of alloy.
It also has a series of excellent properties, than the major: general accounting for 16.5-18.75g/cm3, high strength: tensile strength of 700-1000Mpa, a strong ability to absorb rays: its ability to lead than the 30-40% high, thermal conductivity coefficient: Die Steel for 5 times; thermal expansion coefficient small: only 1/2-1/3 of iron or steel, a good conductive properties; has good weldability and workability. Given the high proportion of the above-mentioned alloy has excellent features, it has been widely used in the aerospace, aviation, military, oil drilling, electrical instrumentation, medical and other industries.
