Non-ferrous metals

Non-ferrous metals are metals that do not have any iron in them at all. This means that Non-ferrous metals are not attracted to a magnet and they also do not rust in the same way when exposed to moisture. Typical Non-ferrous metals include copper, aluminium (coke cans), tin and zinc.

Non-ferrous metals
Aluminium cans

Metal Alloys

Alloys are substances that contain two or more different metals and occasionally other elements. The metals are carefully chosen and mixed to achieve specific properties these include reducing the melting point making the alloy light weight, etc.

Metal type Metal uses Melting point Example product
Aluminium - tends to be light in colour although it can be polished to a mirror like appearance. It is very light in weight. Learn more >> Used for saucepans. cooking foil, window frames, ladders, expensive bicycles. 660°C Aluminium
Copper – is a ductile and malleable metal. It is often red / brown in colour. It is a very good conductor of heat and electricity. Learn more >> Used for plumbing, electric components, cookware and roof coverings. 1084°C Copper
Tin – Is very ductile and very malleable. It is resistant to corrosion from moisture. It is bright silver in appearance. Tinplate is steel with a tin coating. Learn more >> Used as a coating on food cans, beer cans. Used as whistles, tin foil and soldering. 231°C Tin
Zinc – is very resistant to corrosion from moisture. However zinc is a very weak material. Learn more >> Used as a coating on screws, steel buckets, American cents. It is also used to galvanise steel. 419°C Zinc
Brass – Is often cast and machined then plated. It is yellow in colour and is a mixture of 65% copper and 35% zinc. Learn more >> It is used for decorative metal work such as door handles, candle sticks, musical instruments, ornaments. 900–940 °C depending on composition Brass
Casting alloy – This looks like aluminium and is used for casting. It is aluminium with 3% copper and 5% silicon. Learn more >>

Used for sand casting, die casting, engine parts, casting in schools. 660°C Casting alloy
