High-Density Tungsten Alloy Supplier in China - ASTM B777 Certified Products from a Reliable Factory
Description
The most important characteristic of tungsten alloys is their high density of 19.25 g/cm³, which is very close to the density of gold (19.3 g/cm³). Tungsten alloy blocks are manufactured from high-quality tungsten alloy materials, with common compositions including tungsten–nickel–iron or tungsten–nickel–copper. The volume of these blocks can be customized according to customer requirements or designed specifically for your needs by our team.
