Stainless steel. Pure Metals such as pure aluminium or pure copper, contain only one type of metal. The two links or elements of a machine, when in contact with each other, are said to form a pair. 2/15/10) * Engr 241 Introduction The properties and behavior of metals (and alloys) depend on their: Structure Processing history and Composition * Engr 241 Structure of Alloys An alloy is the combination of two or more chemical elements, one being a metal. Two types of iron were initially recognised: White iron: Exhibits a white, crystalline fracture surface because fracture occurs along the iron carbide plates; it is the result of metastable solidification (Fe 3 C eutectic) Classification. A large number of metals are available in nature. Classification of Alloys There are several alloys of various metals, such as alloys of Aluminium, Potassium, Iron, Cobalt, Nickel, Copper, Gallium, Silver, Tin, Gold, Mercury, Lead, Bismuth, Zirconium, and rare earth. Alloys and pure metals often have special High speed steel.
