High specific gravity tungsten alloy materials can be divided into tungsten-nickel-iron alloy, tungsten-nickel-copper alloy and tungsten-molybdenum-nickel-iron alloy.
The main brands of tungsten-nickel-iron alloy are: W90NiFe, W93NiFe, W95NiFe
Tungsten-nickel-iron alloy is an alloy composed of tungsten as the base and adding a small amount of nickel, iron and other alloying elements. It has: high density (~18.8g/cm3) and adjustable, strong ability to absorb high-energy rays (1/3 higher than the ray absorption coefficient of lead), low thermal expansion coefficient (4~6×10-6/℃), good plasticity, strength and elasticity It has the characteristics of high modulus, processability, and weldability. It is widely used in radiation protection and guidance (hyperlink), industrial counterweight components (hyperlink), safety and defense components (hyperlink), etc. Mainly used in radiation protection and guidance industry, industrial counterweight components, safety and defense components, nuclear power and energy components.
The main grades of tungsten-nickel-copper alloy are: W90NiCu, Wu93NiCu, Wu95NiCu
Tungsten-nickel-copper alloy is an alloy composed of tungsten as the base and adding a small amount of nickel, copper and other alloying elements. It has: Non-magnetic, high density (~18.8g/cm3) and adjustable, strong ability to absorb high-energy rays (1/3 higher than the ray absorption coefficient of lead), low thermal expansion coefficient (4~6×10-6/℃), can Processing, weldability and other features. It is widely used in the fields of radiation shielding and protection that are sensitive to magnetic environments.
The main grades of tungsten-molybdenum-nickel-iron alloy are: 90WMoNiFe
Tungsten-molybdenum-nickel-iron alloy is an alloy composed of tungsten as the matrix and adding a small amount of nickel, iron, molybdenum and other alloying elements. It is made of powder metallurgy. Production method, because this material has a low expansion coefficient, high thermal conductivity, and good red hardness, it is widely used in the field of die-casting molds and anvils in the field of hot forging valves.
