1.5mm Thickness Aluminum Sheet A1050
A1050 aluminum sheet in 1.5mm thickness is a practical, high-purity aluminum product valued for its excellent corrosion resistance, high electrical and thermal conductivity, strong formability, and clean surface appearance. As a member of the 1xxx series, A1050 is commonly selected when ease of fabrication and reliable performance matter more than high structural strength. In 1.5mm gauge, it balances rigidity and bendability, making it a frequent choice for cladding, insulation jacketing, lighting components, panels, ducts, and general fabrication.

Features of 1.5mm A1050 Aluminum Sheet
High corrosion resistance for long service life
A1050 naturally forms a stable oxide film, which helps it resist atmospheric corrosion. This makes 1.5mm sheet dependable for indoor use and many outdoor uses when design avoids crevice traps and galvanic coupling.
Excellent formability and bend performance
At 1.5mm thickness, A1050 is easy to bend, roll, press, and draw. It is commonly chosen for parts that require tight radii, deep forming, or frequent forming operations without cracking, especially in softer tempers.
High thermal and electrical conductivity
A1050 is widely used where heat transfer or electrical conduction is important. While it is not a copper replacement in compact high-load conductors, it is very effective in busbar covers, heat shields, reflectors, HVAC components, and thermal layers.
Clean, uniform surface for finishing
The alloy supports anodizing, brushing, polishing, and coating well. Surface appearance depends on rolling finish and quality grade, but A1050 is generally preferred when a bright, consistent surface is required.
Strong weldability and joinability
A1050 can be welded with common methods such as TIG and MIG, and it also performs well with riveting and adhesive bonding. Since it is not heat-treatable for strength, welding does not "ruin" heat treatment-but it can soften work-hardened tempers in the heat-affected zone.
Common Applications
| Application Area | Why A1050 1.5mm Fits Well |
|---|---|
| Building cladding, flashings, trims | Corrosion resistance, easy forming, low weight |
| Insulation jacketing, HVAC ducting | Formability, thermal performance, clean finish |
| Lighting reflectors, signage back panels | Reflectivity, surface uniformity, easy fabrication |
| Appliance liners and covers | Formability, cleanliness, corrosion resistance |
| General sheet-metal fabrication | Reliable bending and cutting at 1.5mm gauge |
| Electrical and thermal components (non-structural) | Conductivity and stable performance |
A1050 is non-heat-treatable; strength is primarily adjusted by cold work (work hardening) and partial annealing. Temper choice affects flatness, formability, and dent resistance.
| Temper (common) | Typical Character | Best For |
|---|---|---|
| O (Annealed) | Softest, maximum ductility | Deep drawing, tight bends, complex forming |
| H12 / H14 | Light-to-medium work hardened | General fabrication, better dent resistance than O |
| H16 / H18 | Higher hardness and strength | Stiffer panels, parts needing higher surface durability |
Note: Availability varies by mill and region; H14 is widely stocked for sheet applications.

Processing Notes Customers Appreciate
| Operation | Practical Notes for 1.5mm A1050 |
|---|---|
| Cutting (shear/laser/waterjet) | Clean cutting; protect surface with film for cosmetic parts |
| Bending | O temper supports tight radii; harder tempers improve stiffness but reduce bendability |
| Welding | Excellent weldability; expect softening near weld for H tempers |
| Anodizing/painting | Very good; specify surface class and cleanliness requirements |
| Forming | Ideal for rolling, stamping, and light drawing; choose O for deep forming |
