Tungsten heater is used in vacuum coating furnace, which is widely used to coat the surface of bottle lid.

Tungsten alloy application in military industry is mainly for aerospace, weapon and nuclear industry. Tungsten alloy (WHA) is heavy metal with main content of tungsten 90~97%, and other elements, such as copper, nickel, iron, manganese, and molybdenum.

1. Lithium Ion Battery in Daily Life
Lithium-ion batteries have become the main power source choice for portable electronic devices due to their large capacity, high voltage, and long life. In order to further satisfy people's demand for higher-performance lithium-ion batteries, it is an effective solution to find alternative electrode materials with better electrochemical characteristics.

1.Tungstic Acid
Tungstic acid is a yellow shiny sheet crystal or crystalline powder, soluble in water, insoluble in ethanol, slightly soluble in ammonia. 

Tungsten alloy application in civil industry including the grade of WNIFE, WNICU, WNIFECO, WNIFEMO, and the content from 90%W to 97%W.

Tungsten alloy shielding is made by tungsten nickel copper alloy or tungsten nickel iron alloy instead of lead or steel, and used to shield the radiations.
