- Product Details
Description
W-Ni-Fe high density tungsten alloys bar is a regular product for QSs tungsten product line. W-Ni-Fe is a very important tungsten alloy. Compared with steel, W-Ni-Fe bar has much higher thermal conductivity with much smaller thermal expansion coefficient. The application of W-Ni-Fe tungsten alloy are focused on its high density and hardness. Thus, high density tungsten alloys has been the most important material for armor piercing shell and fragments. It also consumed in large quantity as cutting tools and aviation industries.
