What are the characteristics of Chalco 5056 aviation aluminum wire?

Good surface quality

  • Surface flatness: the surface should be smooth and flat, without significant protrusions or depressions.
  • Surface cleanliness: the surface should be free from impurities such as oil, dust, and oxide scale.

Good processing properties

  • Good plasticity suitable for deep drawing;
  • Good weldability suitable for various welding methods;
  • Good machinability suitable for various cutting and drilling operations.

Light weight

Compared with other metal materials, aluminum alloy has a lower density, which can reduce the weight of the structure and help improve the fuel efficiency and load capacity of the aircraft.
