ASTM B777 Tungsten Heavy Alloy Rod Tungsten Nickel Copper Alloy Bar
Tungsten Nickel Copper Alloy Bar Tungsten Heavy Alloy Rod
Our tungsten-based high-density alloy Tungsten Nickel Copper Alloy Bar Tungsten Heavy Alloy Rod is an alloy with tungsten as the matrix (90-95% W content), with elements such as Ni and Cu added, and the density is as high as 16.8-18.8 g/cm3. 2. The tungsten-nickel-iron high specific gravity alloy is an alloy composed of tungsten as the matrix (90-97% W content) and elements such as Ni, Fe, etc., and its density is as high as 16.8-18.8 g/cm3. WNiCu alloy is produced through liquid-phase sintering and alloying with added elements. Due to the different characteristics and uses of the alloy, the main components can be divided into W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag and other series.
The tensile strength of Tungsten Nickel Copper Alloy Bar is between 750 ~ 1100MPa. It has a super ability to absorb light. Its ability to absorb light is 30% to 40% higher than that of lead. The thermal conductivity of W-Ni-Cu alloy is 5 times that of steel molds. Tungsten nickel copper is a non-magnetic metal. Due to the toxicity of lead, tungsten nickel copper alloy has excellent environmental performance, so tungsten alloy is a good substitute for lead in many aspects.
