What Is 1050 Aluminum Plate?
1050 aluminum plate belongs to the 1xxx series of commercial pure aluminum alloys. It contains at least 99.5% aluminum and is commonly designated as AA1050, EN AW-1050A or Al99.5. Because of its high aluminum content, 1050 plate offers strong corrosion resistance, high ductility, good reflectivity and excellent thermal and electrical conductivity.
This alloy is non-heat-treatable. Its mechanical strength is primarily adjusted through cold working and annealing conditions, including O, H12, H14, H16, H18, H22, H24 and H112. 1050 aluminum plate is especially suitable for bending, spinning, stamping, deep drawing, reflective surfaces, electrical components, chemical equipment and decorative applications.
Excellent Formability
1050 aluminum is soft and ductile, making it suitable for bending, stamping, spinning, drawing and other cold forming operations.
High Conductivity
With high purity aluminum content, 1050 plate provides good electrical and thermal conductivity for conductive and heat-transfer applications.
Strong Corrosion Resistance
A natural aluminum oxide film helps protect the material in atmospheric and freshwater environments.
1050 aluminum plate has relatively low mechanical strength compared with 3xxx, 5xxx and 6xxx aluminum alloys. It is generally not recommended as the primary material for high-load or critical structural applications. For higher strength requirements, consider 3003, 5052, 5083, 5754, 6061 or 6082 aluminum alloys.

Key Properties of 1050 Aluminum Plate
1050 aluminum plate is often selected where high purity, forming capability, corrosion resistance and conductivity are more important than high mechanical strength.
Corrosion Resistance
1050 aluminum naturally develops a dense oxide film that provides resistance to atmospheric and freshwater corrosion. Surface treatment may be recommended for more demanding environments.
Electrical Conductivity
The high aluminum content makes 1050 suitable for conductive components, busbar-related products, transformer materials and electrical connection applications.
Thermal Conductivity
1050 aluminum transfers heat efficiently and can be used in heat dissipation, thermal shielding and heat transfer-related applications.
Surface Reflectivity
With polished, brushed, anodized or mirror processing, 1050 aluminum can provide attractive and reflective surfaces.
Weldability
1050 aluminum generally has good weldability by common aluminum welding processes. Final welding parameters should be confirmed by actual joint design and application requirements.
Machinability
Machinability is generally fair to poor because soft aluminum may adhere to cutting tools. Sharp tooling, correct lubrication and controlled cutting conditions are recommended.
