Stainless steel
ferrous alloy
- cutlery, cookware and surgical tools and equipment
-Corrosion resistant, high tensile strength, very durable
temperature resistant
Grey cast iron
ferrous alloy
- high amount of carbon than white cast iron
- used for cookware, radiators and stoves
- hard and good resistance to oxidation yet brittle and has low impact resistance
- distributes heat evenly (good for cooking) and has good compressive strength
White cast iron
ferrous alloy
- lower amount of carbon than grey cast iron
uses - dies and extrusion nozzles
excellent resistance to abrasion and great tensile strength
however, it is more brittle than grey cast iron
Brass
non ferrous alloy
- made from copper and zinc
- has a low melting point
- self-lubricating so often used to make musical instruments
- good electrical and thermal conductor
Die steel
ferrous alloy
- hard and durable due to its natural oxide layer which also helps to prevent corrosion
- used for dies
Duralumin
non ferrous alloy
aluminium and copper
Pewter
ferrous alloy
95% tin, copper and antimony (harder)
trophies, decorative items, flasks
low melting point, soft and malleable, soft at room temperature
Low carbon steel
ferrous alloy
ferrous metal with 0.05 - 0.25% carbon
nuts, bolts, refrigerator panels, car parts
malleable, ductile, good tensile strength but lower than high carbon steel
Gold
non-ferrous
jewellery, electronics and ornaments
least reactive metal, ductile, malleable, inactive to alkali
good conductor
Titanium
non-ferrous
used for joint replacements, golf clubs and plane components
low density (excellent strength-to-weight ratio)
highly corrosion resistant, durable with a high melting point
Silver
non-ferrous
electronics and jewellery
best thermal and electrical conductor, however, due to its relatively high cost, it is commonly replaced by copper
silver is also ductile (so can be shaped into wires)
Zinc
non-ferrous
rarely used on its own and it is often alloyed or used for batteries and galvanising
excellent corrosion resistant (oxide layer) to protect other metals
ductile and easy to work with
Copper
non-ferrous
used for electrical wires, pipes and plumbing, can also be used for cookware (pots and pans)
excellent conductor of heat and electricity
anti-microbial/anti-bacterial
Bronze
non-ferrous alloy
90% copper and 10% tin
used for statues, medals and coins
forms an oxide layer which makes it corrosion resistant, yet it is quite brittle
Aluminium
non-ferrous
aeroplane parts, bikes and window frames
excellent strength-to-weight ratio, soft, malleable and develops a natural oxide layer to prevent corrosion
Medium carbon steel
ferrous
springs, gears, rail tracks and machine parts
less ductile than low-carbon steel, hard, malleable and tough with good tensile strength
Tin
non-ferrous
used for soldering and tin coating
a soft, malleable metal with a low melting point and good corrosion resistance
High speed steel
ferrous
High-carbon steel is allowed with cobalt, molybdenum and chromium
able to withstand high temperatures without corrosion, and so is often used for drill bits and blades
