Tungsten nickel iron alloy is an important tungsten based heavy alloy. They are alloys composed of nickel and iron added to tungsten, as well as on this basis. On this basis, other metal elements are added to the alloy.
The main grades of tungsten nickel iron alloy include: W90NiFe, W93NiFe, W95NiFe, W97NiFe
Tungsten nickel iron alloy is characterized by high sintering density, good strength and plasticity, and a certain degree of ferromagnetism. Has good plasticity and machinability
Good thermal conductivity and conductivity, beneficial for γ X-rays or X-rays have excellent absorption ability.
The characteristics of tungsten nickel iron alloy: specific gravity: generally ranging from 16.5 to 18.75g/cm3; High strength: The tensile strength is 700-1000Mpa;
Strong radiation absorption ability: 30-40% higher than lead; High thermal conductivity: The thermal conductivity of tungsten alloy is 5 times that of mold steel; Low coefficient of thermal expansion:
Only 1/2-1/3 of iron or steel; Good conductivity; Widely used in the lighting and welding industries due to its excellent conductivity;
Has good weldability and processability.
Tungsten molybdenum nickel iron alloy is an alloy composed of tungsten as the matrix and a small amount of alloy elements such as nickel, iron, molybdenum, etc. It is produced by powder metallurgy,
Due to its low coefficient of expansion, high thermal conductivity, and excellent red hardness, this material is widely used in the field of die-casting molds
Used in the field of hot forged valve anvil blocks. The materials of high density tungsten alloys can be divided into tungsten nickel iron alloys, tungsten nickel copper alloys, and tungsten molybdenum nickel iron alloys.
The main grades of tungsten molybdenum nickel iron alloy include: 90WMoNiFe element W90 Mo4 Ni4 Fe2
Tungsten alloys are used in the field of die-casting.
Hot riveted bearing material (90WMoNiFe/93WNiFe), due to its good comprehensive high-temperature performance, can be used as a hot riveted bearing material.
