High Quality Zinc metal is used in a number of applications like galvanizing, oxides, die castings and alloys.
Major applications of zinc include:
Brass and bronze (16%)
Other alloys (21%)
Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten zinc.
The zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron.
A widely used zinc alloy is brass, in which copper is alloyed with anywhere from 3% to 45% zinc, depending upon the type of brass. Brass is generally more ductile and stronger than copper, and has superior corrosion resistance. these properties make it useful in communication equipment, hardware, musical instruments, and water valves.
Alloys of zinc with small amounts of copper, aluminium, and magnesium are useful in die casting as well as spin casting, especially in the automotive, electrical, and hardware industries.
Zinc oxide is widely used as a white pigment in paints and as a catalyst in the manufacture of rubber to disburse heat.
The semiconductor properties of zinc oxide make it useful in varistors and photocopying products.
Zinc oxide is used to protect rubber polymers and plastics from ultraviolet radiation.
