Zinc is a vital mineral that the body needs for immune function and metabolism. It is also a typical alloy metal.
Zinc and copper alloys are used in the automotive industry for the manufacture of pipes and clutches. Zinc is very common for surface treatments, especially for galvanising and hot dip galvanising.
Other uses include zinc-coating on steel for increased corrosion resistance, negative terminals in both alkaline and zinc-carbon batteries, and often in brass alloys.
