Heavy alloy Tungsten alloy Balance Weight) material is a kind of matrix of Tungsten Nickel Copper Alloys (W content of 85-99%), and added with Ni, Cu, Co, Mo, Cr and other elements of the alloy. Press 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, having a density of up to 16 .5-19.0g / cm3, and is the world known high proportion alloy, it has a series of excellent properties, than the major: general proportion of high 16.5-18.75g / cm3 ,, strength: tensile strength of 700-1000Mpa, a strong ability to absorb radiation: its capacity than Lead 30-40%, the thermal conductivity coefficient: 5-fold mold steel; thermal expansion coefficient is small: Only iron or 1 / 2-1 / 3, good conductive properties of steel; has good weldability and formability ʱ?? Given the high proportion alloy has the above excellent features, it is widely used in aerospace, aviation, military, oil drilling, electrical instrumentation, medical and other industries.
