Metals vary in this respect; pure gold is the most malleable. Silver, copper, aluminum, lead, tin, zinc, and iron are also very malleable. Some heating usually increases malleability.Zinc, for example, at ordinary temperatures is very brittle, but is malleable in the temperature range from about 120Â°C. to 150Â°C. Impurities adversely affect the malleability of metals.The Columbia Electronic Encyclopedia, 6th ed.

Some heating usually increases malleability.
The zinc is, of course, anodic and corrodes at a faster rate than normal, particularly in the vicinity of the exposed steel. Any tendency for the steel to corrode is counteracted by the flow of electrons from the corroding zinc to the steel surface (cathodic protection). 10. âWhat are the Limitations of Zinc Plating?â Zinc should not be used on critical steel parts that will reach temperatures of 500ËF, or higher, as zinc may diffuse into grain boundaries to embrittle the steel.
