Properties of ferrous metals

Name 4 ferrous metals

• Cast iron

• High carbon steel

• Low carbon steel

• Stainless steel

Advantages, disadvantages and uses of cast iron

Advantages

• 3 - 3.5% carbon

• Good compressive strength

• Hard

• Relatively cheap

Disadvantages

• Brittle compared to other ferrous metals

• Difficult to machine
