1370 mirror aluminum plate
1370 mirror aluminum plate is a high-purity aluminum product designed for applications that require a bright, reflective, and clean surface. With aluminum content typically above 99.7%, alloy 1370 offers excellent electrical and thermal conductivity, very good corrosion resistance, and reliable formability. When processed into a mirror-finish plate, it combines the intrinsic purity of the alloy with an attractive specular surface, making it suitable for both functional and decorative uses.
For buyers, this material is valued for its balance of reflectivity, conductivity, lightweight performance, and surface quality. It is often selected for lighting reflectors, decorative panels, electrical components, signage, and specialized industrial uses where appearance and performance matter at the same time.

What Is 1370 Mirror Aluminum Plate?
1370 is a commercially pure aluminum alloy known primarily for its conductivity and corrosion resistance. Compared with higher-strength alloy families, it is softer and less alloyed, which helps preserve purity-related properties. When manufactured as a mirror aluminum plate, the sheet undergoes advanced rolling, polishing, and sometimes anodizing or coating to create a highly reflective surface.
This combination gives the material two important values:
| Value Type | Benefit |
|---|---|
| Functional value | Strong light reflection, heat reflection, conductivity, corrosion resistance |
| Aesthetic value | Smooth appearance, bright surface, modern metallic look |
Because of these properties, 1370 mirror aluminum plate is often chosen when customers need a material that looks premium but is still easy to fabricate and lightweight.
Features
| Feature | Performance Advantage |
|---|---|
| High purity aluminum | Supports excellent electrical and thermal conductivity |
| Mirror surface | Delivers strong reflectivity and clean visual appeal |
| Low density | Helps reduce total component weight |
| Good corrosion resistance | Performs well in many indoor and mild outdoor environments |
| Good workability | Suitable for cutting, bending, stamping, and forming |
| Non-magnetic nature | Useful in specific electrical and industrial applications |
| Recyclability | Environmentally friendly and economically recoverable |
High Reflectivity
One of the most attractive features of 1370 mirror aluminum plate is its high surface reflectance. This makes it useful for luminaires, solar reflective parts, appliance trim, and interior architectural features. A well-finished mirror surface can reflect both visible light and radiant heat efficiently.
Excellent Conductivity
Because of its high aluminum content, 1370 provides superior conductivity compared with many stronger but more heavily alloyed aluminum materials. This makes it suitable for specialized electrical or heat-transfer-related uses where a reflective surface is also desirable.
Corrosion Resistance
The natural oxide film formed on aluminum helps protect the plate from corrosion. In indoor, dry, or mildly humid environments, 1370 mirror aluminum plate generally performs very well. Additional coating or anodizing can further improve surface durability.
Chemical Composition
The exact composition may vary slightly by production standard and supplier, but typical values for 1370 alloy are shown below.
| Element | Typical Content (%) |
|---|---|
| Aluminum, Al | 99.70 min |
| Silicon, Si | 0.10 max |
| Iron, Fe | 0.20 max |
| Copper, Cu | 0.01 max |
| Manganese, Mn | 0.01 max |
| Magnesium, Mg | 0.01 max |
| Zinc, Zn | 0.02 max |
| Titanium, Ti | 0.02 max |
| Others, each | 0.03 max |
| Others, total | 0.10 max |
The extremely high aluminum content is the main reason this alloy performs so well in conductivity and corrosion resistance, while also supporting a fine mirror finishing process.

Mechanical and Physical Properties
Since 1370 is a high-purity aluminum alloy, its mechanical strength is lower than many structural aluminum alloys. However, it offers strong physical performance in applications where conductivity, surface quality, and light weight are more important than high load-bearing strength.
| Property | Typical Value |
|---|---|
| Density | 2.70 g/cm³ |
| Electrical conductivity | Approx. 61–63% IACS or higher |
| Thermal conductivity | Approx. 220–235 W/m·K |
| Tensile strength, O temper | Approx. 60–95 MPa |
| Tensile strength, H18 temper | Approx. 110–145 MPa |
| Yield strength, O temper | Approx. 20–35 MPa |
| Elongation | Good, varies by temper and thickness |
| Melting range | Approx. 643–657°C |
These values are typical reference data and may differ depending on processing route, final temper, and quality standard.
Alloy Temper Conditions
The temper condition affects hardness, formability, and strength. Customers should choose the temper based on fabrication requirements.
| Temper | Description | Typical Benefit |
|---|---|---|
| O | Annealed, soft | Best formability and bending performance |
| H14 | Strain hardened, half hard | Balanced strength and workability |
| H16 | Strain hardened | Higher hardness with moderate formability |
| H18 | Full hard | Maximum strength among common tempers |
For deep forming or complex shapes, O temper is often preferred. For flatter panels and applications requiring better stiffness, H14 to H18 may be more suitable.
Surface Finish Options
The mirror effect can be achieved through different finishing routes, and the final choice affects both appearance and durability.
| Finish Type | Characteristics | Typical Use |
|---|---|---|
| Polished mirror | Strong metallic reflection | Decorative panels, signage |
| Rolled mirror | Uniform industrial bright finish | General reflector applications |
| Anodized mirror | Improved surface protection | Interior architecture, appliances |
| Coated mirror | Enhanced color and weather resistance | Decorative and semi-exterior use |
A protective film is commonly applied during transport and fabrication to preserve the mirror surface from scratches.
Common Applications
| Application Area | Typical Use |
|---|---|
| Lighting industry | Lamp reflectors, luminaire panels, light control surfaces |
| Decoration | Wall panels, ceiling trims, display fixtures, elevator interiors |
| Electrical field | Conductive parts, specialized bus-related components, covers |
| Home appliances | Reflective decorative elements, inner trim panels |
| Solar and energy | Reflective backing and light-management components |
| Signage | Premium sign boards and branded display panels |
In many of these applications, the appeal of 1370 mirror aluminum plate is not just its visual brightness, but also its clean processing behavior and low weight.
Processing and Fabrication Notes
| Process | Suitability |
|---|---|
| Cutting | Excellent |
| Shearing | Excellent |
| Bending | Good to excellent, depending on temper |
| Stamping | Good in softer tempers |
| Welding | Generally possible, but surface finish may be affected |
| Anodizing | Good |
| Printing/lamination | Good with proper surface preparation |
To maintain the mirror effect, careful handling is essential during slitting, bending, packaging, and installation. Surface scratches, oil contamination, or rough tooling can reduce visual quality quickly.
