In 1808, aluminum oxide was electrolyzed in the laboratory and became aluminum. In 1884, it was used as a building material on the top of Washington Monument; The aluminum alloy materials synthesized by adding various metal elements to aluminum have been widely used in various links in the construction industry. The thickness of common aluminum alloy plates: generally 0.8-1.2mm for advanced metal roof (and curtain wall) systems (while it is generally ≥ 2.5mm for traditional systems)

The production process of 3000 series aluminum plate is excellent. 3000 series aluminum plate is mainly composed of manganese. The content is between 1.0-1.5. It is a series with good antirust function. It is commonly used in air conditioners, refrigerators, car bottoms and other humid environments, and the price is higher than 1000 series. It is a commonly used alloy series.
