The brushed aluminum strips are widely used in signs, lighting, interior and exterior decoration, household appliances, luggage, gifts, furniture, consumer electronics and other fields. The wire drawing process is mainly divided into three parts: devinegar, sand mill, and water washing.
In the production process of the brushed aluminum trim strips, the metal surface will clearly shows every minute trace. In recent years, more and more metal shells of electronic products choose this brushed aluminum strip because of its beautiful and anti-corrosive effect. What are the aluminum alloys suitable for wire drawing?
Pure Aluminum
The typical ones are 1050, 1060 and 1100. The purity can reach more than 99.00%. With simple technical elements and production process, its price is relatively cheap.
Aluminum Alloy
2xxx aluminum strip features high hardness with high copper content of about 3-5%. It belongs to aircraft aluminum alloy, which is not often used in conventional industries.
3xxx aluminum alloy is a kind of Al-Mn alloy. Its typical ones are 3003, 3004 and 3A21. It has excellent anti-rust function, which is used in humid environments such as air conditioners, refrigerators and cold storage.
5xxx aluminum alloy is a kind of Al-Mg aluminum metal strip. The commonly used ones are 5052, 5005, 5083 and 5A05 aluminum strips. It features low density, high tensile strength and high elongation. In the same area, the weight of 5xxx aluminum alloy is lower than other series. It has good wire drawing effect.
6xxx brushed aluminum strip has two popular grade:f 6061 and 6063. It is very suitable for applications with high requirements for corrosion resistance and oxidation such as aircraft joints.
The typical ones of 7xxx aluminum alloy is 7075 aluminum strip, featuring high-hardness and high-strength, which is often used to make airplanes.
