1050 1060 1070 1085 mirror polished aluminum sheet

06/13 2025

When it comes to superior quality, durability, and an aesthetically appealing finish, mirror polished aluminum sheets is know as an exceptional choice. Among these, aluminum sheets made from alloys 1050, 1060, 1070, and 1085 offer a compelling balance of high purity, excellent corrosion resistance, and outstanding surface finish.

Aluminum Alloys 1050, 1060, 1070, and 1085: Chemical Composition & Characteristics

The alloys 1050, 1060, 1070, and 1085 belong to the 1xxx series — commercially pure aluminum grades (with aluminum content exceeding 99%). Here is a breakdown of typical chemical compositions according to international standards (all values in % by weight):

Alloy	Aluminum (Al)	Silicon (Si)	Iron (Fe)	Copper (Cu)	Manganese (Mn)	Magnesium (Mg)	Zinc (Zn)	Titanium (Ti)	Others (Each)	Others (Total)
1050	99.5 min	≤ 0.25	≤ 0.40	≤ 0.05	≤ 0.05	≤ 0.03	≤ 0.05	≤ 0.03	≤ 0.03	≤ 0.10
1060	99.6 min	≤ 0.25	≤ 0.35	≤ 0.05	≤ 0.05	≤ 0.03	≤ 0.05	≤ 0.03	≤ 0.03	≤ 0.10
1070	99.7 min	≤ 0.25	≤ 0.35	≤ 0.05	≤ 0.05	≤ 0.03	≤ 0.05	≤ 0.03	≤ 0.03	≤ 0.10
1085	99.85 min	≤ 0.25	≤ 0.35	≤ 0.05	≤ 0.05	≤ 0.03	≤ 0.05	≤ 0.03	≤ 0.03	≤ 0.10

These grades offer ascending purity and hence progressively better corrosion resistance and electrical conductivity.

Features of 1050/1060/1070/1085 Mirror Polished Aluminum Sheets

1. High Surface Reflectivity

The mirror polish finishes are attained by successive finishing and buffing processes producing brilliantly reflective surfaces free of blemishes.
These polished sheets deliver, reflectivity above 90%, drastically enhancing their aesthetic and functional value.

2. Exceptional Corrosion Resistance

The commercially pure nature imparts superior corrosion resistance specifically against atmospheric, marine, and chemical environments.
Minimizes oxidation, corrosion, and tarnishing over time making the sheets apt for exposed conditions.

3. Excellent Formability & Workability

Alloy 1xxx series aluminum is soft, ductile, meaning easy to cut, bend, roll or shape which is critical for customized applications.
Suitable for all kinds of forming/processes including deep drawing and stretch forming without compromising the polish.

4. Lightweight with Great Strength

Retains enough mechanical strength for a variety of medium mechanical loads while enabling considerably reduced structures compared to heavier metals.
Surface hardness supports good scratching resistance given proper handling.

5. Chemical & Thermal Stability

Can withstand mild chemical atmosphere concentrations and consecutive thermal cycling.
Maintains mirror polish quality over a broad allowable temperature range.
