Metals
Alloys
Mixtures of two or more metals, in order to get the best properties of both.
Brass
Malleable and easy to cast
Uses: musical instruments, plumbing
Stainless Steel
Doesn't t rust, hard and smooth
Uses: Cutlery, metal tools
High speed steel
Hard, tough, highly resistant to frictional heat
Uses: Tool blades, drill bits, milling cutters
Bronze
Tough, corrosion resistant and can be cast
Uses: Statues, coins and bearings
Pewter
Malleable, low melting point and casts
Uses: Jewellery, goblets, decorative items
Non-ferrous
Metals that do not contain iron, so are not magnetic and will rust/ tarnish
Aluminium
Light, high strength to weight ratio and ductile
Uses: Pots, pans, cars, cans
Copper
Ductile, malleable and good conductor
Uses: Plumbing supplies and cables
Tin
Soft, malleable and good conductor
Uses: Used as a protective coating
Titanium
Hard, good strength to weight ratio and high corrosion resistance
Uses: Hip replacements, golf clubs and aircraft
Gold
Malleable, ductile and corrosion resistant
Uses: Jewellery, electronic components
Silver
Malleable, ductile and can be soldered
Uses: Jewellery, cutlery and plating other metals
Ferrous
Metals that contain iron, so are magnetic and will rust
Low Carbon
Steel
Tough and ductile and easily machined and welded
Uses: Construction, screws, cars
High Carbon
Steel
Hard and wears well
Uses: Tools, blades and knives
Cast Iron
Hard but brittle. Easily cast but hard to machine
Uses: Pots, pans, vices
Medium
Carbon Steel
Less ductile, malleable and tough
Uses: Springs and gardening tools
