seeba Fact Sheet
Zinc: Cas Number 7440-66-6

 

The fact sheet is generated by materials/substance legislation compliance software produced by PlesTech Ltd.,

 

Substance: Zinc (Zn) - Metal


Physical Properties

Atomic / Molecular weight = 65.37
Density = 7.13 gm/cc
Melting temperature = 419.5°C
Boiling point = 906°C
Specific heat = 0.0915 cal/°C at 20°C
Resistivity = 0.06 ohms-mm2 / m at 20°C
Zinc is normally economic to recycle


Toxicity

Zinc is an essential element in the growth of human beings and animals, and is not normally considered
toxic. However zinc in excess can affect the blood, brain, eyes, kidney, pancreas, and throat. Symptons of
zinc toxicity include nausea, vomiting and fever. Recent research indicates zinc toxicity could contribute to
neuronal loss in the brain.

Very toxic for water organisms.


Applications

Plating of screws and other metal components.

The metal is employed to form numerous alloys with other metals. Steel, brass, nickel silver, commercial
bronze, spring bronze, German silver, soft solder, and aluminum solder are some of the more important
alloys. Large quantities of zinc are used to produce die castings, used extensively by the automotive, electrical,
and hardware industries.

It is widely used in the manufacture of paints, rubber products, cosmetics, pharmaceuticals, floor coverings,
plastics, printing inks, soap, storage batteries, textiles, electrical equipment, and other products.
