• Cast iron - hard material, tough, ductile, elastic.

  Used for electrical fittings and equipment, hand tools, pipe fittings, washers, brackets
• Mild Steel - high tensile strength, high impact strength, good ductility and weldability, magnetic, good malleability

  Used for structural steel, signs, automobiles, furniture, decorations, wire, fencing, nails
• High Carbon Steel - highest hardness and toughness for carbon steels and lowest ductility

  Used for cutting tools, springs, coils
• Stainless Steel - corrosion resistant, high tensile strength, durable, temp resistant

  Used for grills, cookers, saucepans, sinks
• Zinc - Brittle metal, easy to fabricate, high corrosion resistance, low density, non magnetic

  Used for paints, rubber, cosmetics plastic, inks, soaps, batteries
• Aluminium - Ductile, lightweight, soft, malleable, high corrosion resistance, non magnetic

  Used for cans, foils, kitchen utensils, window frames
• Bronze - easy to fabricate, high corrosion resistance, low density, non magnetic

  Used for coins, hardware mounts, furniture trim, ceiling or wall panels, ship hardware
• Copper - easy to fabricate, high corrosion resistance, low density, non magnetic

  Used for wiring, motors
• Brittle - Easily broken, damaged
• Ductile - Able to be drawn into a thin wire
• Hardness - Quality or condition of being hard
• Elasticity - Able to distort its size and shape and go back
• Malleable - Able to be shaped by hammering, forging
• Toughness - Strong enough to withstand rough handling
• Alloy

  Solder

  Magnesium-silicon

  Brass

  Aluminium alloy
• Brazing:

  • Emery cloth - clean rust off metal before brazing
  • Flux - applied to base material to stop oxide formation
  • Brazing rod - rod of metal melted to join other pieces of metal together
  • Health and Safety - A visor, leather gloves, apron, and leggings
