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.
Brass has higher malleability than bronze or zinc. The relatively low melting point of brass (900 to 940 Â°C, 1652 to 1724 Â°F, depending on composition) and its flow characteristics make it a relatively easy material to cast.o enhance the machinability of brass, lead is often added in concentrations of around 2%. Since lead has a lower melting point than the other constituents of the brass, it tends to migrate towards the grain boundaries in the form of globules as it cools from casting.
