What is 1070 Aluminum
1070 Aluminum is a commercially pure aluminum alloy in the 1xxx series, with a minimum aluminum content of 99.70%. Its high purity and low content of alloying elements give it excellent electrical conductivity, thermal conductivity, corrosion resistance, and formability. These properties make 1070 Aluminum a reliable material for applications that prioritize conductivity, purity, and ease of processing over high mechanical strength.
Unlike heat-treatable aluminum alloys such as 6061, 1070 Aluminum cannot gain strength through conventional precipitation heat treatment. Manufacturers typically adjust its mechanical properties through cold working and annealing, supplying different tempers to meet specific fabrication requirements.

Key Properties of 1070 Aluminum
Outstanding Conductivity
1070 grade aluminum boasts superior electrical conductivity reaching roughly 62% IACS, alongside thermal conductivity values around 226 W/(m·K).
Reliable Weldability
1070 aluminum is well-suited for mainstream aluminum welding techniques. Sound welded joints can be achieved by adopting proper operation parameters and matching filler metals.
Superior Forming Performance
Thanks to outstanding ductility, this alloy supports easy processing operations including bending, rolling, stamping, spinning and deep drawing. The O temper state delivers the best forming capability.

Anodizing
Anodizing forms a protective oxide layer that improves corrosion resistance, surface hardness, and appearance. It is suitable for decorative and architectural applications.
Polishing
Polishing smooths the aluminum surface and creates a bright, clean finish. It is commonly used for decorative parts and reflective components.
Brushing
Brushing creates a uniform linear texture on the surface, providing a modern appearance while reducing the visibility of minor scratches and marks.
Coating
Coating adds a protective or decorative layer to improve weather resistance, corrosion protection, and color durability. Common options include PVDF and powder coating.
Embossing
Embossing creates a textured surface that improves appearance and surface durability while concealing minor imperfections.
Perforating
Perforating creates precisely arranged holes for ventilation, filtration, light transmission, and weight reduction.
