An alternative to steel plates

An aluminum alloy plate that is 1.5 times stronger than the standard aluminum alloy plate (A5052). It can be used as an alternative to cold rolled steel sheets, in various types of housing and electrical/information equipment. Both its lighter weight and thinner structure result in cost reductions.

Features

  • 1.5 times stronger than A5052, the representative aluminum alloy plate for use in structures. This enables thinner walled structures, resulting in lower weight and cost.
  • It has equivalent strength to cold rolled steel sheets, which it can replace to achieve lighter weight.
  • GC150 has 32% elongation compared with the 25% of A5052 soft material (0 material), enabling previously problematic bending and deep drawing.

Applications

Various housings including PDP back covers, digital cameras, CD ROMs, MD frames, general electrical and information equipment

Properties

1.5X increase in tensile strength, proof stress
