Contain iron and are magnetic due to iron content. They are prone to rust and require a protective finish to prevent corrosion. Malleability and hardness depends on carbon content- the more carbon the harder and less malleable the steel becomes.
Cast iron:
-Brittle if thin
-Can be cast in a mould
-Strong compressive strength
-Good electrical and thermal conductivity
-Poor resistance to corrosion.
-Used for gates, manhole covers, drains and vices.
High carbon steel:
-It's hard and brittle
-Less malleable than mild steel.
-Good electrical and thermal conductor.
-Uses include tools, screwdrivers, and chisels.
Low carbon steel or mild steel:
-Ductile and tough.
-Easy to shape, braze and weld.
-Good conductor of heat and electricity.
-Corrodes easily.
-Used as nuts and bolts, screws, bicycle frames and car parts.
Stainless steel:
-It's a ferrous alloy. shiny silver when polished.
-Hard and tough.
-Good resistance to stains and corrosion.
-Shiny silver when polished.
-Used extensively in kitchen sinks, cutlery and hospital equipment.
-Stainless steel is also used in architecture, aerospace and general transport.

Non-ferrous metals:
They don't contain iron, aren't magnetic and don't rust.
Aluminium:
-It's lightweight, malleable and strong.
-Good conductor of heat and electricity.
-Used in drinks cans, cycle frames and saucepans.
Copper:
-Very malleable and an excellent conductor of electricity and heat – perfect for plumbing and central heating applications.
-It is orange/brown when polished, but will oxidise green.
