Aluminum Alloy 1070

Aluminum Alloy 1070 is a commercially pure aluminum grade from the 1xxx series, containing a minimum of approximately 99.7% aluminum. Due to its high purity, this alloy provides excellent electrical conductivity, superior corrosion resistance, high thermal conductivity, and outstanding formability. Aluminum 1070 is widely selected in industries where purity, surface quality, and conductivity are more important than high mechanical strength. Aluminum 1070 is commercially available in various forms including sheets, plates, coils, strips, foils, bars, and extruded profiles. This alloy is commonly used for electrical components such as busbars, transformer parts, conductor strips, and power distribution applications. It is also used in heat exchangers, cooling systems, lighting reflectors, decorative panels, chemical equipment, packaging industries, and general industrial components due to its excellent fabrication characteristics.

The main advantages of Aluminum Alloy 1070 include lightweight structure, excellent corrosion resistance, high reflectivity, easy welding and brazing capability, excellent anodizing performance, and superior machinability for forming operations. Commercial supply options are available in different tempers such as O (annealed), H12, H14, H16, and H18 depending on required hardness and mechanical properties. Aluminum 1070 is an ideal choice for manufacturers looking for high-purity aluminum solutions for electrical, thermal, architectural, and industrial applications.
