Among all series, the 1000 series aluminum alloys contains the most aluminum, and the purity can reach more than 99.00%. The minimum aluminum content of the 1000 series aluminum plate is determined based on the last two Arabic numerals of the series. For example, the last two Arabic numerals of the 1050 series aluminum alloys are 50. According to the international brand naming principles, the aluminum content must reach more than 99.5% to be a qualified product.
The first series of aluminum has good formability and surface treatment properties, and its corrosion resistance is the best among aluminum alloys. Its strength is low, and the higher the purity, the lower its strength.

1N00 | 1N00 | The strength is slightly higher than 1100, the formability is good, and its chemical properties are the same as 1100. |
The commonly used ones on mobile phones are 1050, 1070, 1080, 1085, and 110 aluminum alloys, which are used for simple extrusion molding (no bending). Among them, 1050 and 1100 aluminum alloys can be used for chemical sanding, glossy, matte, and normal effects, with obvious material textures and good coloring effects; 1080 and 1085 mirror aluminum are often used for bright characters, matte effects, and no obvious material textures. .
A series of aluminum materials are relatively soft and are mainly used for decorative or interior parts.
