Tungsten-based high specific gravity alloy

High density tungsten alloy is a kind of tungsten matrix (W content 85-99%), and add Ni, Cu, Co, Mo, Cr and other elements of the alloy. According to the composition characteristics and uses of the alloy is divided into W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, and other major series, its density is as high as 16 .5-19.0g/cm3, which is called high specific gravity alloy. It also has a series of excellent characteristics, with large specific gravity: general specific gravity of 16.5-18.75g/cm3, high strength: tensile strength of 700-1000Mpa, strong ability to absorb rays: its ability is 30-40% higher than lead, and its thermal conductivity is large: 5 times that of die steel; Small thermal expansion coefficient: only 1/2-1/3 of iron or steel, good electrical conductivity; It has good weldability and workability.
