Metals
Types Of Metals
the range of metals are classifeid as Non Ferrous and Ferrous
Metals can then be seperated under these headings into Alloys and Non Alloys
Ferrous Metals: Metals that contain iron and carbon
Non Ferrous: Metals that do not contain Iron
Ferrous Alloys: Mixture of two metals, atleast one of the metals contains iron and carbon
Non Ferrous Alloys: Mixture of two metals that do not contain carbon or iron
Ferrous: Mild Stell; Strong and cheap, can rust ( car bodies and white gold)
High Carbon Steel; Harder than mild steel, hard to work and can rust (drills and files)
Cast Iron; Hard, Brittle under impact ( brake discs, engines)
Non Ferrous: Aluminium; Leightweight, cheap, rusts easily ( car bodies, screws, nuts)
Brass; Strong, ductile, looks good ( door furniture, door nobs, electric parts)
Copper; Soft metal, good conductor of electricity ( wires, pipping)
Ferrous Alloys:Stainless Steel
High Speed Steel
Die (tools) Steel
Non Ferrous Alloys:Brass
Bronze
Duralumim
Gold is the only metal that is extracted and usable without processing, all other metals are from ores
Common Metal Ores:
Iron
Copper
Aluminium
Lead
Tin
Zinc
25% of the earth crust is made up of metal ores, Aluminium is the most common followed by iron
The rarer the metal the more expensive
