Description of Aluminum-Copper (Al-Cu) Master Alloy
Al-Cu alloys are the earliest cast aluminum alloys used in the industry. It has a simple casting process, good cutting performance, and excellent heat resistance. The disadvantage is that the casting property of the solid solution alloy is poor, the potential difference between the copper-rich phase and the substrate is large, the corrosion resistance is low, and the density is large.

Applications of Aluminum-Copper (Al-Cu) Master Alloy
The aluminum-copper master alloy is used for the addition of copper in aluminum alloy smelting, with low addition temperature and precise composition control. It is also a cheap replacement of copper wire. It can be made into sheets, forgings, aerospace structural parts, electrode solder, machined products, and engine piston wheels.
Packing of Aluminum-Copper (Al-Cu) Master Alloy
All packaging materials are suitable for air, sea and road freight. Vacuum packing is also available for selected alloys. Great care is taken to avoid any damage which might be caused during storage or transportation.
