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.

The longevity of a sacrificial zinc anode is a function of its weight. When a zinc lasts less than a year, you need one with more weight. Normally, however, you are not faced with determining the appropriate anode size (other than diameter for a zinc shaft collar).
