Metals Almost 75% of all elements are metals. Metals are used in electronics for wires and in cookware for pots and pans because they conduct electricity and heat well. Most metals are malleable and ductile and are, in general, heavier than the other elemental substances. Two or more metals can be alloyed to create materials with properties that do not exist in a pure metal. All metals can be classified as either ferrous or non-ferrous. Ferrous metals contain iron and non-ferrous metals do not. All ferrous metals are magnetic and have poor corrosion resistance while non-ferrous metals are typically non-magnetic and have more corrosion resistance. An overview of the most common ferrous and non-ferrous metals is shown below. Ferrous Metals Material name Composition Properties Applications Low Carbon Steels Up to 0.30% Carbon Good formability, good weld-ability, low cost 0.1%-0.2% carbon: Chains, stampings, rivets, nails, wire, pipe, and where very soft, plastic steel is needed.0.2%-0.3% carbon: Machine and structural parts Medium Carbon Steels 0.30% to 0.80% Carbon A good balance of properties, fair formability 0.3%-0.4% carbon: Lead screws, gears, worms, spindles, shafts, and machine parts. 0.4%-0.5% carbon: Crankshafts, gears, axles, mandrels, tool shanks, and heat-treated machine parts 0.6%-0.8% carbon: "Low carbon tool steel" and is used where shock strength is wanted.
