The aluminum trim coil for gutter on the market mainly choose 3000 Al- Mn and 6000 Al-Mg alloy. With reference to relevant domestic and foreign standards and specifications, as well as the analysis and comparison of the various properties of them, a conclusion can be drawn: the 6-series aluminum-magnesium alloy is not suitable for gutter.
3000 aluminum alloy
1. Anti-rust aluminum: It has good corrosion resistance.
2. Good weather resistance: It maintains stable performance in the temperature range of -45° to 260°C.
6000 aluminum alloy
1. Non-rust-proof aluminum: It has poor acid and alkali resistance and corrosion resistance.
2. Forged aluminum: Recycled aluminum is mostly used, which is brittle in texture and poor in processing technology.
3xxx aluminum coil is well known as aluminum-manganese alloy. The content of manganese is 1-1.5%. It is a widely used anti-rust aluminum alloy series. The strength of the 3 series aluminum alloy is higher than that of pure aluminum alloy. Although it cannot be heat treated to strengthen the performance, it has good plasticity after cold working (under-cold rolling mill) and annealing process.
The main grades of 3xxx aluminum alloys are 3003, 3004, 3005, 3104 and 3105,etc. . Among them, the 3003 aluminum alloy is the most used. The 3003 aluminum coil is easy to process and has good rust resistance. It can be painted with PVDF or PE paint to be used in roof system.
3003 aluminum coil price is also cheaper than that of 5052, and the welding performance is also very good. Some truck fuel tank material manufacturers also use 3003H24 aluminum plates to make baffle in the oil tank.
