To color includes most metals except iron and its alloys, which form the group of ferrous metals. But if you compare production, non-ferrous metals are less common and their production is much more expensive than iron. However, base metals have extraordinary qualities in comparison with iron. And they could be called «the League of extraordinary gentlemen». The term «nonferrous metal» due to the color of some metals, such as copper gives the alloy a reddish tint. The alloys have improved properties compared with pure metals. They are divided into alloys of heavy metals, such as tungsten, molybdenum, rhenium and alloys of light metals — magnesium, aluminium, titanium etc.
- heavy metals: tungsten, molybdenum, Nickel, lead;
- light metals: aluminum, magnesium, sodium, potassium, titanium;
- precious metals: gold, silver, platinum;
- small metals: bismuth, cadmium, cobalt, antimony, mercury;
- refractory metals: tungsten, molybdenum, vanadium, tantalum, niobium, manganese, zirconium:
- rare earth metals: these include all the lanthanides;
- soft: indium, lead, antimony and the whole group of fusible metals;
- solid: tungsten, titanium, and the whole group of refractory metals:
- scattered: hafnium, indium, germanium, thallium, rhenium and selenium;
- radioactive: uranium, radium, plutonium etc.
Non-ferrous metals, modern industry uses in alloys, allowing «dosing» of their physical and technological quality. In addition, properties of nonferrous alloys depend on the heat treatment. So the strength is increased after strain-hardening, natural or artificial aging. Nonferrous metals are available all types of machining — rolling, pressing, forging, stamping, cutting, welding. From alloys manufactures castings, bar stock, flat and profile rolling. Refractory metals are used as powders for powder metallurgy products. Powders of such metals as zinc, aluminum relevant to the manufacture of paints and anticorrosive coatings.
