-
Ferrous Metals
- contain iron
- most are magnetic
-
Stainless Steel
- ferrous metal
- tough hard metal
- corrosion resistant
- wears well and is difficult to cut
- used for cutlery, sinks and pans
-
Mild Steel
- ferrous metal
- high tensile srength
- poor resistance to corrosion
- easily melded
- used in car bodies, nuts and bolts
-
High Carbon Steel
- ferrous metal
- very hard
- quite brittle
- poor resistance to corrosion
- used for files/ chisels/ tool blades/ knives
-
Non Ferrous Metal
- do not contain iron
- not magenetic
- can be pure metals or alloys
-
Copper
- non ferrous metal
- tough, ductile and malleable
- very good conductor
- corrosion resistant and solders well
- used for wiring, circuit boards
-
Aluminium
- good strength to weight ratio
- malleable and ductile
- resists corrosion
- conducts heat and electricity well
- used for drink cans, pans, kitchen foil
-
Alloys
- a mixture of different metals
- each metal provides different properties to create a unique metal
-
Bronze
- alloy
- mixture of copper and tin
- tough and strong
- wears very well
- used for coins
-
Brass
- alloy
- mixture of copper and zinc
- hard and rigid metal
- can be soldered
- used for instruments
-
Fixings
Gas Welding: oxyacetylene is used to create a very hot flame which welds metal.
