1070 Aluminum Alloy
1070 aluminum sheet/plate
1070 aluminum alloy, belonging to 1000 series aluminum, is considered commercially pure and the aluminum content reaches up to 99.7%. This aluminum is characterized by low specific resistance, good electrical conductivity, outstanding elongation, good formability and corrosion resistance, good weldability, and much lower price than copper. These characteristics enables it to be widely used as conductive aluminum busbar in high voltage power station, high voltage distribution room, electrolytic aluminum workshop and other high voltage, strong current equipment.
1070 aluminum alloy is widely used for busbars, heat-exchangers, metallizing, electrical material, building and construction, transport, high-end oxidizing material, electronic aluminum foil, PS plates, strips for ornaments, communication cables, for joining two pieces of aluminum.
