Fundamentals of Mechanical Engineering Zinc is obtained from zinc ore 'blended (zinc sulphide)' and 'calamine (zinc carbonate)'. Zinc is a fairly heavy, bluish white metal. It has good corrosion resistance and is very cheap. Its melting point is 419° C. Method of applying zinc coating is known as galvanizing. Brass is the most widely used copper zinc alloy.
