Because of its bright surface, light weight, and reliable processing performance, it is widely used in architectural decoration, lighting, interior design, signage, and household appliance panels.
For customers looking for a material that offers both premium appearance and stable manufacturing performance, 1070-H18 gold mirror aluminum coil is a practical and cost-effective choice.
What Is 1070-H18 Gold Mirror Aluminum Coil?
1070 aluminum belongs to the 1xxx series pure aluminum alloy, containing very high aluminum content. It is known for excellent corrosion resistance, high thermal conductivity, strong reflectivity, and good workability. After mirror polishing and gold surface treatment, the coil gains a luxurious metallic appearance suitable for decorative and reflective applications.
The H18 temper means the material is strain-hardened to a fully hard condition. This temper provides higher strength than softer tempers while maintaining enough stability for roll forming, stamping, and panel fabrication in suitable designs.

Mechanical Properties of 1070-H18
The H18 temper is the fully hard condition produced by cold working. It offers greater hardness and tensile strength than softer tempers such as O, H14, or H16.
| Property | Typical Value |
|---|---|
| Temper | H18 |
| Tensile strength | 95 – 135 MPa |
| Yield strength | ≥ 75 MPa |
| Elongation | Low compared with soft temper |
| Hardness | Higher than H14/H16 |
| Formability | Suitable for controlled bending and roll forming |
| Density | 2.71 g/cm³ |
Because H18 is a hard temper, it is better suited for applications requiring surface stability and rigidity, while deep drawing or severe forming may require a softer alloy temper.
Physical Properties
| Property | Typical Value |
|---|---|
| Density | 2.71 g/cm³ |
| Melting point | Approx. 660°C |
| Thermal conductivity | Approx. 230 W/m·K |
| Electrical conductivity | Approx. 59–62% IACS |
| Reflectivity | High, dependent on mirror treatment |
| Corrosion resistance | Excellent in general atmosphere |
| Non-magnetic | Yes |
Surface Structure and Processing Details
Gold mirror aluminum coil is typically produced through a combination of rolling, polishing, cleaning, mirror finishing, and coloring treatment. Depending on the production technology, the gold effect may be achieved by coated, anodized, or laminated decorative processing.
