Prime Western Zinc 98.65%
Zinc, a bluish-white moderately hard metal is very common and is used especially to make brass and as a protective coating for things made of iron and steel. It is brittle at room temperature and at temperatures above 150°C, being workable only in the range between 100°C and 150°C. It is a dynamic metal and will dislodge hydrogen even from dilute acids. The principal use of zinc is for the galvanizing of iron sheets or wires.
