When we polish metals, they are also good reflectors of light. Properties of Metals Conductors Metals are good conductors of electricity and heat Properties of Metals A chemical property of metal is its reaction with water and oxygen. See our User Agreement and Privacy Policy. Identify each of the following alloys: A mixture of iron with carbon. An alloy is a homogeneous mixture of a metal with other metals or non metal. Most pure metals are either too soft, brittle, or chemically reactive for practical use. Alloys are made by combining two or more elements. Useful websites for further information.

Ferro-alloys such as Ferro-chromium and Ferro-silicon, for instance, are produced by smelting mixed ores and are used in the production of various steels. METALS AND ALLOY However, there are several processes such as case-hardening, hardening, tempering, normalizing and annealing which can be employed to counteract some of these properties. An Introduction to Metal Alloys. A metal alloy is a metallic substance, but it is not a single chemical element. For more detailed instructions, see the Getting Started presentation. There will always be a trade-off between hardness and brittleness when combining carbon with steel. Hasse Fredriksson KTH, Royal Institute of Technology, Stockholm, Sweden. 7. iii) Reaction with acids:-Metals react with dilute acids to form salts and hydrogen.
