Mirror aluminum sheets have become a preferred choice in various industries due to their superior reflective properties, lightweight nature, and corrosion resistance. Among the wide selection, 3105 H14 H16 polished mirror aluminum sheets is know for their excellent combination of mechanical strength, formability, and surface finish.
About 3105 H14 H16 Polished Mirror Aluminum Sheets
The 3105 alloy is an aluminum-manganese based material, known for a balanced mix of strength, corrosion resistance, and good weldability. The designation H14 and H16 refer to tempering conditions indicating the hardening extent due to cold working - with H14 being partially hard and H16 representing a slightly harder temper.
When polished to a mirror finish, these aluminum sheets exhibit an outstanding glossy appearance coupled with excellent durability and reflectivity. This makes them suitable for aesthetic and functional applications requiring both style and performance.
Functions and Advantages
The core functions of 3105 H14 H16 polished mirror aluminum sheets include:
- High Reflectivity: The polished mirror surface provides luminescent quality, serving visually decorative and reflective functions.
- Corrosion Resistance: Naturally forming aluminum oxide layer resists atmospheric corrosion, suitable for indoor and outdoor uses.
- Lightweight Yet Strong: Cold working achieves optimal mechanical strength without causing brittleness, making the sheets easy to handle and install.
- Formability: Good ductility and strain hardening features facilitate bending, rolling, and forming processes.
- Energy Efficient: Reflective properties help in energy-saving architectural applications by reflecting light and heat.
- Non-Toxic and Environmentally Friendly: Safe for contact with food products and recyclable.
Typical Applications
3105 polished mirror aluminum sheets serve diverse industries, including:
- Architectural Decoration: Wall panels, ceilings, elevator panels, and signage benefiting from a high-quality, corrosion-resistant finish.
- Advertising Media: Reflection-based display boards, light reflectors, and advertising boards.
- Automotive Trim: Protective and reflective trim parts.
- Kitchenware and Appliances: Cookware, decorative surfaces on home appliances like refrigerators and ovens.
- Lighting Fixtures: Enhanced reflectivity improves efficient lighting.
- Household Products: Mirrors, photo frames, and DIY crafts.
Such versatility makes the 3105 mirror aluminum a practical choice wherever aesthetic appeal and functional performance intersect.
Chemical Composition
Chemical composition governs the material behavior significantly. The following table lists typical chemical constituents of 3105 alloy according to ASTM B209 / JIS H4000 standard.
| Element | Content (wt%) |
|---|---|
| Aluminum (Al) | Balance (~97.3-98.9) |
| Manganese (Mn) | 0.5 – 1.0 |
| Iron (Fe) | ≤ 0.7 |
| Silicon (Si) | ≤ 0.4 |
| Copper (Cu) | ≤ 0.1 |
| Zinc (Zn) | ≤ 0.1 |
| Titanium (Ti) | ≤ 0.2 |
| Others (each) | ≤ 0.05 |
This alloy composition balances alloying elements to enhance strength and corrosion resistance while ensuring excellent polishing characteristics.
Temper Conditions (H14 and H16) and Mechanical Properties
The following table demonstrates properties of 3105 aluminum sheets in H14 and H16 tempers. The tempering treatments correspond to cold-worked conditions achieving increments in strength.
| Parameter | H14 (Half-Hard) | H16 (Full-Hard) |
|---|---|---|
| Tensile Strength (MPa) | 130 – 160 | 185 – 215 |
| Yield Strength (MPa) | 65 – 110 | 155 – 185 |
| Elongation (%) | 2 – 5 | 1 – 3 |
| Hardness (Brinell) | ~45 – 55 | ~85 – 95 |
Both temper states provide different levels of mechanical strength suitable for diverse forming processes-H14 for moderate forming, and H16 suited for tougher applications needing higher strength.
Technical Specifications and Standards
The following technical specifications apply widely to polished 3105 relatable products:
| Standard | Specifics |
|---|---|
| ASTM B209 | Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate |
| JIS H4000 | Aluminum and aluminum alloy sheet and plate |
| Thickness Range | 0.3 mm to 4.0 mm |
| Width | Typically 1000 mm to 1600 mm |
| Surface Finish | Bright Polished Mirror Finish (Ra < 0.5μm) |
| Coating/Chemical Treatment | Often supplied without any coating to retain mirror finish or anodized to improve corrosion immunity |
Manufacturers frequently conduct polishing through multi-stage mechanical buffing and electro-polishing to achieve smoothness and mirror quality.
3105 H14 H16 polished mirror aluminum sheets are distinguished by their superior strength, corrosion resistance, and striking glossy finish demanded in architecture, signage, automotive parts, kitchenware, and more. This alloy provides a balanced chemistry primarily involving manganese for strengthening without sacrificing formability or polished reflectivity.
Their adherence to international standards like ASTM B209 ensures reproducibility of features and flexibility in diverse country markets. Combined with variable temper choices of H14 and H16, manufacturers can match mechanical requirements depending on handling and durability needs.
If your project requires attractiveness paired with longevity and practical formability, the 3105 mirror aluminum sheet is often the perfect candidate.
