Lesson Explainer: Alloys Nagwa

An alloy is a mixture of chemical elements of which at least one is a metal. Unlike chemical compounds with metallic bases, an alloy will retain all the properties of a metal in the resulting material, such as electrical conductivity, ductility, opacity, and luster, but may have properties that differ from those of the pure metals, such as increased strength or hardness. In some cases, an alloy may reduce t… 網頁2024年2月4日 · The most important metallic component of an alloy (often representing 90 percent or more of the material) is called the main metal, the parent metal, or the base metal. The other components of an alloy (which are called alloying agents ) can be either metals or nonmetals and they're present in much smaller quantities (sometimes less than … 網頁This explains why an alloy often has more uses than the pure elements it is made from. Pure iron, for example, is very soft. Adding a small amount of tungsten to iron makes tool … forever 21 towson
