92.5W W-Ni-Fe Tungsten Nickel Iron Or Tungsten Nickel Copper Alloy Cube
1. Description of W-Ni-Fe/W-Ni-Cu Alloy Cube:
Because tungsten-nickel-iron and tungsten-nickel-copper cubes have a series of excellent characteristics such as high density, high melting point, small capacity, ultra-high hardness, excellent wear resistance, extremely high tensile strength and high temperature resistance, especially Due to the radiation absorbing ability of tungsten alloy cubes, tungsten alloy cubes are widely used in medical fields, such as radiation shielding walls, CT and tungsten alloy cubes used.
Tungsten alloy cubes are popular because of their high density, high temperature resistance, impact and crack resistance, high seismic strength, and good corrosion resistance.
We can process according to customer's drawing.

3.Features of W-Ni-Fe/W-Ni-Cu Alloy Cube:
A: Tungsten Nickel Iron Alloy:
High sintering density, strong strength and plasticity, and some ferromagnetism define tungsten-nickel-iron alloy. It possesses great X-ray or -ray absorption capacity, strong thermal conductivity, good electrical conductivity, and good plasticity and machinability.
(1) General specific gravity ranges between 16.5 and 18.75 g/cm3.
(2) High strength: tensile strength is 700-1000Mpa;
(3) Excellent radiation absorption: 30–40% more than lead;
(4) High thermal conductivity: Die steel's thermal conductivity is 5 times that of tungsten alloy;
(5) A low thermal expansion coefficient, around 1/2 to 1/3 that of steel or iron;
(6) Excellent electrical conductivity; utilized extensively in the electric welding and lighting sectors;
(7) Has good weldability and processability
B: Tungsten Nickel Copper Alloy:
The added nickel-copper ratio (weight) is generally 3:2. Compared with tungsten-nickel-iron alloy, copper does not have the effect of nickel and iron to activate sintered tungsten, so its sintered density is slightly lower, its strength and plasticity are poor, and heat treatment and deformation processing are generally not performed.
