The main difference between aluminum 5083 and 6061 lies in their chemical composition, physical properties, and processing characteristics. Specifically as follows:
1, chemical composition
5083 aluminum alloy contains 4% to 4.9% magnesium and 0.4% to 1% manganese, which is a non-heat-treatable alloy, suitable for welding assemblies that require high welding efficiency and maximum joint strength; 6061 aluminum alloy contains a certain proportion of magnesium and silicon, which is an alloy that can be heat-treated, with good machinability and medium strength.
2,Physical Properties
The density of 5083 aluminum alloy is 2.66g/cm3, the melting point ranges from 580 to 640°C, the specific heat capacity is 899J/kg-K, and the coefficient of thermal expansion is 23.8×10^-6/K; 6061 aluminum alloy's physical properties, such as density and melting point, are slightly different from 5083.
3,Processing characteristics
5083 aluminum alloy is suitable for welded assemblies requiring high welding efficiency and maximum joint strength, with good cold forming, welding and spot welding properties; 6061 aluminum alloy has better machinability, especially the 6061-T651 version, which can be machined by single-point or multi-axis diamond tools.
