![]() ![]() Modern pewter Pb replaced by Sb with some Cu and Metal fittings, metal ware (often electroplated) Impure Fe, C up to 4½ with Mn, P, Si, and S Special alloysĪre used for such purposes as die-casting, dentistry, high-temperature applications, Solders contain tin with lead and bismuth type metal is an alloy of lead, tin,Īre those used in coins: modern "silver" coinage in most countries is anĪlloy of nickel and copper. The very light but strong alloys used in aircraft construction are frequently Brass and bronze, two well-known and ancient metals,Īre alloys of copper, while pewter is an alloy of tin and lead. Which all contain a large proportion of iron and small amounts of carbon and other elements. The commonest alloys are the different forms of steel, Of alloy structures in general is complex. Or interstitial, depending on the relative sizes of the atoms. Structures of alloys consisting mainly of one component may be substitutional Alloys are formed by mixing their molten components. Varying the proportions of the constituents. Of alloys below, 26 elements are involved.Īlloys are useful because their properties can be adjusted as desired by Melting point are called eutectic mixtures. The resultant physical properties differ from those of the components.Īlloys are general harder and stronger, and have lower melting Them, a heterogeneous mixture, or any combination An alloy may be a compound of the metals, a solid solution of Other metals or non-metals, such as carbon or phosphorus. An alloy is a combination of a metal with one or more ![]()
