Main application areas

1.Electronics and Semiconductors

Chip manufacturing:Tungsten sputtering targets are used for semiconductor coating,and tungsten electrodes are used for integrated circuits.

Electronic packaging:Tungsten copper alloy(W-Cu)is used as a heat dissipation substrate for high-power electronic components due to its high thermal conductivity and low coefficient of expansion.

2.Aerospace

High temperature components,such as rocket nozzles and turbine blades,utilize the high-temperature resistance of tungsten(up to 3000°C or above).

Weight block:Adjust the center of gravity of the aircraft using high-density characteristics.

3.Medical equipment

Radiation therapy:Tungsten alloy shields(such as tungsten rubber)are used to block X-rays and gamma rays.

Surgical tools:Precision surgical instruments made of high hardness tungsten steel.

4.Industrial processing

Molds and cutting tools:Tungsten steel(such as YG hard alloy)is used for high wear cutting tools and stamping molds.

Glass melting:Tungsten crucibles or heating elements are used for high-temperature glass melting.

5.Military Industry and Energy

Armor piercing bullet:High density tungsten alloy is used as the core material.

Nuclear fusion device:tungsten as the first wall material of plasma(such as the ITER project).

Manufacturing process

Powder metallurgy

Tungsten powder compression sintering(traditional method)is suitable for complex shapes but with low precision.

Precision machining

CNC turning/milling,grinding,wire cutting(EDM)machining high-precision components(such as±0.001mm tolerance).

3D printing

Selective laser melting(SLM)technology is used to manufacture complex structural components,such as irregular cooling channels.

Key performance advantages

High temperature resistance:The working temperature can reach over 2000°C in a vacuum or inert environment.

Corrosion resistance:resistant to acid and alkali corrosion(excluding hydrofluoric acid).

Radiation shielding:The absorption capacity of X-rays is 1.7 times that of lead,and it is non-toxic and environmentally friendly.

High rigidity:With an elastic modulus of up to 400 GPa,it is suitable for supporting structures in precision instruments.
