Metals
EN AW-1050A, also known as Al99.5, is an unalloyed aluminum grade with a purity of at least 99.5%. This material is known for its excellent corrosion resistance, high electrical and thermal conductivity, and outstanding formability. Thanks to these properties, it is widely used in applications where electrical conductivity, chemical inertness, and formability are essential.
Common trade names for EN AW-1050A include Al99.5, 3.0255, and A91050.
Thanks to these properties, EN AW-1050A is a popular choice for applications in electrical engineering, chemical industry, and food industry.

Decorative applications after anodizing
EN AW-1050A offers very high purity, excellent corrosion resistance, and superior electrical and thermal conductivity, making it ideal for electrotechnical and chemical‐industry uses.
Yes, EN AW-1050A welds well with common methods like TIG and MIG, although its mechanical strength may decrease in the heat‐affected zone.
Yes, the alloy has excellent anodizability, producing a decorative and protective oxide layer.
Yes, due to its high purity and corrosion resistance, it’s approved for food‐industry applications.
It has relatively low mechanical strength and cannot be hardened by heat treatment, so it’s less suited for high‐load structural parts.
Available as sheets, strips, tubes, and profiles in various thicknesses and dimensions.
It retains toughness and ductility at cryogenic temperatures, making it suitable for very cold environments.
While it has good general corrosion resistance, chloride attack can occur in seawater—additional protective measures are recommended.
