Mirror Finish 1070 H26 Aluminum Sheet

Gnee Steel (Tianjin) Co., Ltd. is one of the most reliable manufacturers and suppliers of mirror finish 1070 h26 aluminum sheet in China. With abundant experience, we warmly welcome you to wholesale high quality mirror finish 1070 h26 aluminum sheet in stock here from our factory. Good service and reasonable price are available.

Mirror finish 1070 H26 aluminum sheet is a high-purity aluminum product (≥99.7% Al) processed with a mechanical or electro-polished mirror surface and strengthened to the H26 temper. It combines excellent reflectivity (85%–95%) with moderate mechanical strength. Supplied by GNEE, this polished aluminum sheet is widely used by global manufacturers for lighting reflectors, commercial decorative panels, and industrial heat-reflective applications.

Key Features of 1070 H26 Reflective Aluminum Plate

• High Reflectivity: Achieves up to 85–95% reflectivity after professional polishing, reducing light loss in fixtures.
• Excellent Corrosion Resistance: The ultra-high purity 1070 alloy ensures a long service life even in humid environments.
• Balanced Temper: The H26 temper (quarter-hard) provides higher physical strength than softer tempers, making it durable for paneling.
• Stable Formability: Allows for standard stamping, cutting, and bending without cracking the base material.
• Surface Ready: Smooth surface highly suitable for subsequent anodizing or protective PE film lamination.

Why Buy 1070 Aluminum For Mirror Finish Projects?

There are many aluminum grades, but 1070 is specifically chosen for mirror applications. Here is why GNEE uses 1070 as the base material:

• Ultra-High Purity: With ≥99.7% aluminum content, it contains very few impurities (like iron or silicon). Fewer impurities mean a brighter, more flawless surface after polishing.
• High Thermal Conductivity: Excellent at dissipating heat, which is a major advantage when used behind hot LED lights or in solar applications.
• Perfect for Anodizing: The high purity allows for excellent anodic oxidation results, creating a hard, clear protective layer over the mirror finish without turning cloudy.

Engineers and purchasing managers can review the core parameters of GNEE's 1070 H26 aluminum below. We support custom OEM sizes.

Because 1070 H26 balances strength and reflection, it is highly practical for industrial and commercial manufacturing. Common uses include:

• Lighting Reflectors: LED industrial high-bay lighting housings, street light reflectors, and indoor commercial lamp covers.
• Architectural Decoration: Reflective wall panels, suspended ceiling systems, and interior elevator cabin decoration.
• Appliance Components: Internal reflective panels for ovens and decorative exterior panels for refrigerators.
• Signage and Advertising: High-visibility advertising boards, nameplates, and commercial display stands.
• Energy and Industry: Solar collector reflective plates and industrial heat-shielding reflectors.

Choosing the right temper is critical for your manufacturing process. While 1070 is the standard alloy for mirror finishes, the temper affects the final result. Here is how H26 compares to 1070 H18 and 1070 H24.

1070 H26 provides higher mechanical strength, making it better for flat structural panels. However, it is less commonly used than 1070 H18 or H24 for ultra-high-end mirror finishing due to the slight difficulty in polishing harder surfaces. If your priority is stiffness, choose H26; if your priority is a flawless mirror finish, ask us about 1070 H18.

GNEE follows a strict production process to ensure the 1070 H26 aluminum meets international export standards.

• Casting: Continuous casting or DC casting to create the base 1070 aluminum ingots.
• Hot and Cold Rolling: The material is hot rolled, then cold rolled to reach the specific target thickness (0.2mm to 2.0mm). The cold-rolling process helps achieve the H26 temper.
• Annealing/Tempering: Heat treatment is applied precisely to stabilize the internal structure and lock in the H26 quarter-hard temper.
• Mechanical Polishing: The sheet passes through specialized roller polishing and buffing machines to create the initial mirror surface.
• Surface Treatment (Optional): The polished surface can be left as-is, or it can be anodized to increase scratch resistance and weather durability.
• Protection and Slitting: A protective PE/PVC film is tightly laminated to the mirror side to prevent scratches. The coil is then cut into specific sheet sizes.

GNEE understands that any surface defect ruins a mirror finish. We implement rigorous quality checks before shipment:

• Surface Inspection: 100% visual and machine inspection to ensure there are no scratches, pits, water stains, or oxidation marks on the mirror side.
• Tolerance Control: Thickness tolerance is strictly controlled within ±0.02mm to ±0.05mm, depending on the thickness.
• Reflectivity Testing: Using light meters to verify the surface hits the promised 85%–95% reflectivity range.
• Flatness Testing: Ensuring the sheet remains perfectly flat, which is crucial for decorative wall panels.

Mirror finish aluminum is highly sensitive to friction and moisture. GNEE uses standard export seaworthy packaging to ensure safe delivery.

• Surface Film: Every single sheet is covered with a tightly bonded PE or PVC protective film.
• Moisture Barrier: The aluminum is wrapped in waterproof kraft paper and heavy-duty plastic film.
• Desiccants: Moisture-absorbing packets are placed inside the packaging to prevent water stains during ocean transit.
• Wooden Pallets: Secured on fumigated export wooden pallets, bound with steel or plastic straps to prevent shifting.
• Delivery Time: Typical lead time is 15–25 days for standard wholesale orders.
