Zinc Coatings

Zinc Coatings

In the coating of sheet or strip, the zinc bath contains a small amount of aluminum ( to %). The aluminum (Al) suppresses the forma tion of the zinciron alloys, resulting in a coating that is mostly zinc. Inline heat treatment can be used to produce a fully alloyed (FeZn) coating, called galvannealed steel.

Zinc Compounds (hazard)

IIISigns, Symptoms, and Syndromes : In the metallurgy of zinc, the hazards of intoxication depend mainly on the concommitant presence of other metals such as arsenic, cadmium, manganese, lead. The presence of arsenic in zinc is a source of exposure to arsine each time it is in contact with strong acids.
