Uri''s Page-Metals Used in Coins and Medals
Metals used in Coins and Medals describes the Elements and Alloys used for their production. Some (but by no means all) of the information came out of ''The Teach Yourself Guide to Numismatics'' by C.C.Chaerlain published in 1960.
Metal - Simple English Wikipedia, the free encyclopedia
Alloys of metals Edit Many things that are made of metals may, in fact, be made of mixtures of at least one metal with either other metals, or with non-metals. These mixtures are called alloys.Some common alloys are: Steel (iron and carbon) (Carbon is a non-metal)

Suppliers of Silicon Metal
Adding silicon metal to aluminium alloys makes them strong and light. As a result they are increasingly used in the automotive industry to replace heavier cast iron components. This allows weight reductions, a reduction in fuel consumption, increased efficiencies and subsequent benefits to the environment by reducing the greenhouse gas emissions and conserving fossil fuels.
Properties, Composition, and Production of Metal Alloys
2/3/2020· Commercial metal alloys attempt to coine these beneficial properties in order to create metals more useful for particular appliions than any of their component elements. Steel , for example, requires the right coination of carbon and iron (about 99% iron and 1% carbon) in order to produce a metal that is stronger, lighter, and more workable than pure iron.

DK Science: Metals - Fact Monster
2/8/2020· Almost three-quarters of all elements are metals, such as gold and silver. There are also some elements we may not think of as metals, such as the calcium in our bones, and the sodium in table salt (sodium chloride). Metals are defined by their METALLIC PROPERTIES, such as high melting points., such as high melting points.

Cobalt is a non-ferrous magnetic metal with high strength and toughness, excellent corrosion and oxidation resistance, and high temperature strength.
The metal has been used to produce very hard alloys with other platinum group metals, for fountain pen tips, for instrument pivots, for gramophone needles and electrical contacts. It is used in some alytic appliions and has an interesting chemistry based on cluster compounds.
Leading Tin Producing Countries In The World - WorldAtlas
Tin is used in the coination with other metals and as a pure metal in the manufacturing of recipients of carbonated drinks, beer, distilled water, and electronic valves. The metal is brought to use for the electro-plating of the small coat around the objects of copper, aluminium and steel.
Journal of the Japan Institute of Metals and Materials
Some mechanical properties of titanium-silver-iron alloys have been studied principally by measuring the K b values of canti-levered specimens. In titanium-silver alloys, the K b value was increased considerably with the addition of silver and reached the value of about 90 kg/mm 2 for the titanium-10% silver alloy,but in the two phase range it was reduced.
