Non-ferrous metals: [Metallurgy] non - ferrous metal, narrow non-ferrous metals is also called nonferrous metal, all metal is iron, manganese, chromium. Generalized non-ferrous metals include non-ferrous alloy. Non-ferrous alloy is a kind of non-ferrous metal matrix (usually greater than 50%), add one or several other elements of the alloy.
Non-ferrous metals usually refers to remove iron (sometimes to remove chromium and manganese) and all metal outside of iron base alloy. Non-ferrous metals can be divided into heavy metals (such as copper, lead, zinc), light metals (such as aluminum, magnesium), precious metals such as gold, silver, platinum and rare metals, such as tungsten, molybdenum, germanium, lithium, lanthanum, uranium).
Non-ferrous alloy strength and hardness of the generally higher than the pure metal, resistance than pure metal, small temperature coefficient of resistance, good comprehensive mechanical properties. The commonly used non-ferrous alloy of aluminum alloy, copper alloy, magnesium alloy, nickel alloy, tin alloy, tantalum alloy, titanium alloy, zinc alloy, molybdenum alloys, zirconium alloys, etc.
