The 6061 and 6063 aluminum sheet grades are commonly used aluminum plates in the 6 series aluminum-magnesium-silicon alloy. Recently, several customers have asked what are the differences between the two. Here are details.
6061 aluminum plate has many advantages such as good oxidation effect, small deformation after processing, uniform quenching, etc. It enjoys a good reputation and reputation in the fields of mobile phone cases, automobile wheels, trolley cases, 3C products, aerospace and other fields. 6061 aluminum plate alloy is widely used in automatic mechanical parts, precision machining, mold manufacturing electronics and precision instruments, SMT, PC board solder carriers, etc. In particular the 6061 5mm thick aluminium sheet for car chassis is among our featured products.
The 6063 alloy aluminum plate is an Al-Mg-Si series high-plasticity alloy, with excellent processing properties, excellent weldability, extrudability and electroplating properties, good corrosion resistance, toughness, easy polishing, and coating , Excellent anodizing effect. Mainly used in building profiles, printing plates, industrial radiators, irrigation pipes and extrusion materials for vehicles, benches, furniture, fences, etc.; high-speed passenger car body structure materials, automobile engine parts, automobile wheels, etc.
| Alloy | Hardness | Cutting property | Anodizing property | Plasticity |
| 6061 | Good | Good | Good | Ordinary |
| 6063 | Ordinary | Ordinary | Good | Good |
By comparison, the overall performance of 6061 is better in application.
