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.

How long you should keep a receipt depends on what it is for. A receipt for merchandise covered by a warranty needs to be filed away safely at least until the warranty runs out. Keep receipts for large purchases until you no longer own the item. For example, suppose you purchase a $4,000 cedar wardrobe and you later decide to sell it. With the receipt, you can show potential buyers the original purchase price. You may also need it for insurance purposes should something happen to the piece.
