schweren Wolfram-Legierung (W-Ni-Cu)

tungsten heavy alloy:The high proportion of material is an alloy of tungsten to the matrix (W content 85-99%), and add a Ni, Cu, Co, Mo, Cr alloy elements. The alloy composition characteristics and uses into W-Ni-Fe, Ni-Cu-W, W-Co, WC-Cu-W, W-Ag, and other major series, the density of up to 16 .5-19.0g/cm3, was called the world a high proportion alloy, which also features a series of outstanding features, than major: general share of 16.5-18.75g/cm3, high strength: tensile strength of 700-1000Mpa, ray absorption ability: the ability to lead than high 30-40%, the thermal conductivity: Die Steel for five times; thermal expansion coefficient small: only come iron or steel, electrical properties can be good; a good solderability and machining. Given the high proportion of the above alloy outstanding feature, and it is widely used in the aerospace, aviation, military, oil drilling, electrical instrumentation, medical and other industries. It used powder compacting plant processing molding high temperature sintering process, the production of high-alloy proportion of 20 tons, the main production equipment 500 tons of hydraulic machines, intermediate frequency sintering furnace.
