Specification of Tin Powder


















Application of Tin Powder

1.Typical applications may include pressed and sintered components, bearings and bushings, metallurgical alloying, chemical processes, friction parts, surface engineering, decorative, welding and brazing, diamond tooling, electronics, radiation shielding, etc.

2.Tin is commonly used as an alloy to make bronze, bell metal, die casting alloy, pewter, soft solder and phosphor bronze.

Chemical Properties of Tin Powder

Tin resists corrosion from wafer,but can be attacked by acids and alkalis. 

Tin can be highly polished and is used as a protective coat for other metals.

A protective oxide (passivation) layer prevents further oxidation, the same that forms on pewter and other tin alloys.

Tin acts as a catalyst when oxygen  is in solution and helps accelerate chemical attack.
