• What are some examples of ferrous metals ?


  High carbon steel, stainless steel, iron, alloy steel
• What is iron?


  A strong magnetic metal, very versatile
• What is high carbon steel?


  An extremely strong, durable but less duticile material then regular steel, used for cutting tools and toughened blades
• What is stainless steel?


  Has chromium added which creates a silver surface, hygienic, durable, aesthetically pleasing, used in cutlery and car design and architecture and domestic products
• What happens when more carbon is added to steel?

• What is medium carbon steel ?


  0.25% to 0.5% carbon is good for forging car parts
• What is high carbon steel?


  0.55% to 95% carbon, products that will need to withstand high forces such as high tension rope
• What is alloy steel?


  Alloy steel contains elements such as nickel and copper, it can contain a vary from 1% to 50% of different elements, this can improve mechanical properties.
• What is a non ferrous metal?


  Metals that do not contain iron
• What are some examples of ferrous metals?


  Aluminium, copper, lead, zinc, magnesium, silver, gold, tin
• What is copper?


  It's easy to bend maellable, ductile( can be stretched easily into long wires), and excellent conductor
• What precious metals are there and what properties do they have?
