Evaporation Polishing Tungsten Boat
Evaporation Polishing Tungsten Boat Description
Evaporation Polishing Tungsten Boat is boat-shaped parts made of tungsten powder through powder metallurgy process. Wires can be connected at both ends, and low-melting-point metal is placed in the recess in the middle. When electricity is applied, its temperature rises to below 2000 degrees, causing the metal to evaporate into Gas, plated on the surface of the workpiece above. Evaporation Polishing Tungsten Boat has a series of excellent properties such as high melting point, high strength, high hardness, low vapor pressure, high temperature resistance, strong creep resistance, good electrical and thermal conductivity, wear resistance, corrosion resistance, long service life, etc. According to different uses, it can be divided into stamping boats, welding boats, riveting boats and other types. Evaporation Polishing Tungsten Boat is most commonly used in evaporation industry or vacuum coating technology, especially playing an important role in semiconductor devices, optical materials, solar energy, automobile manufacturing and medical fields.
