Study Notes

Non-Ferrous Metals Characteristics

  • Non-ferrous metals are known for their ductility, malleability, corrosion resistance, and ability to conduct electricity and heat.

Aluminium

  • Lightweight material commonly used in various industries.
  • Can be welded using Metal Inert Gas (MIG) and Tungsten Inert Gas (TIG) techniques.
  • Melting temperature is 660°C.
  • Common applications include drinks cans, aircraft bodies, and baking foil.

Copper

  • Notable for its toughness and high conductivity.
  • Versatile; can be soldered or brazed.
  • Melting temperature is 1080°C.
  • Widely used in electrical wiring and water pipes.

Zinc

  • Melting temperature is relatively low at 420°C.
  • Primarily used for galvanizing steel, protecting items like dustbins and buckets.

Silver

  • Can be soldered, enhancing its versatility in jewelry making.
  • Melting temperature is 960°C.
  • Commonly utilized in jewelry and cutlery manufacturing.

Gold

  • Another metal that can be soldered.
  • Melting temperature is 1060°C.
  • Frequently used in jewelry and electronic switch components due to its excellent conductivity.

Titanium

  • Known for its hardness and lightweight properties.
  • Malleable at high temperatures, facilitating various applications.
  • Melting temperature is 1670°C.
  • Used in medical applications like tooth implants and high-performance bicycles.

Tin

  • Has a low melting temperature of 230°C.
  • Mostly applied as a coating for food cans to prevent corrosion.
