    Zinc has never been found naturally in its pure form. It can be alloyed (mixed) with a number of other metals. Zinc is brittle at ordinary temperatures but is malleable and ductile (can be beaten and drawn into a wire) when heated to 1000 C. Zinc has a relatively low melting point and is a good electrical conductor.
