Aluminum alloys properties

Aluminum has only 1/3 weight of steel, while being lightweight this metal remains extremely stable. It is easy to form, resistant to heat effects and corrosion as well it is proven that this metal is a very good electric conductor.

It is the second most flexible metal and sixth most plastic.

Aluminum is one of the most popular engineering metals, because it is:

  • Lightweight
  • Strong
  • Resistant to Corrosion
  • Durable
  • Plastic
  • Flexible
  • Electrically Conductive
  • Non-toxic
  • Thermally Conductive
  • Easy to Form

These positive features make aluminum the most widely used metal in the industry. Especially transport, construction, electricity and furniture industries are using this metal.

This metal is being used in many products, including cans, foils, kitchen accessories, window frames, beer barrels, airplane parts, electronic devices, vehicles, railings, sports equipment, boat equipment and many other products.

Aluminum is often used as an alloy with other metals as it gives better durability and strength. Alloys with copper, magnesium and manganese and silicon are lightweight but strong.

Aluminum is used in power lines for its electrical conductivity. It is cheaper and lighter than copper.

In global practice, most commonly used standards, such as European (EN 573, 754, 755, 485, 515, 573), Germany (DIN 1735, 1748, 9714, 1712, 1725, 1747, 1769, 1770, 9714, 9713, 1771, 1745, 1738, 1745, 1783, 1998, 1999, 1796, 59700, 1797, 59701, 59600, 1746, 1795, 9107, 59751)
