Metals

• Ferrous: metals contain iron and are attracted to magnets
• Non-Ferrous metals: do not contain iron and are not attracted to magnets
• Ferrous metals will rust unless their surface is coated with another material
• Ferrous metal examples: cast iron, mild steel, carbon steel, stainless steel , galvanised steel
• Non-ferrous metals: They react less with water, many react with oxygen to form a coating that protects the underlying metal
• Non-furrous metals examples- aluminium, copper, gold, silver, lead, zinc
• Alloys examples: stainless steel, brass, bronze, solder
• steel= Alloy of iron and carbon
• Stainless steel= Alloy of iron and chromium
• Galvanised Steel=Steel with a thin coating of zinc
• Bronze= Alloy of copper and zinc
• Solder= Alloy of tin and lead
