Main series and preparation process of high-density tungsten alloys
The main series of high-density tungsten alloys are W-Ni-Cu and W-Ni-Fe, among which W-Ni-Cu series is non-magnetic alloy. This alloy is widely used in the fields of defense industry, aerospace industry, medical industry, electrical industry and oil drilling, such as rocket nozzles, die-casting molds, armor-piercing cores, contacts, heating elements, heat shields, counterweights, weighted rods, etc.
In addition, the preparation process of high-density tungsten alloys is diverse, among which powder metallurgy is the mature mainstream production process for manufacturing high-density tungsten alloy products.
