5083 vs 6061 aluminum sheet

5083 aluminum alloy and 6061 aluminum alloy are both commonly used aluminum alloy grades, which differ in alloy composition, performance and use. 5083 alloy usually has better high temperature resistance than 6061 alloy, but in daily use, 6061 alloy is more common because it has good processing and welding properties.

5083 vs 6061

5053 aluminum plate is a non-heat-treatable alloy. Its high hardness is mainly due to its high magnesium alloy content, but it is difficult to process, so the price is relatively high. The hardness can reach around 70-80HB. It is a commonly used alloy in shipbuilding and equipment processing. It has good bending performance in 0 state and H321 state. 5083 aluminum plate is a product that can be bent and has a relatively high hardness. It is widely used in the shipbuilding industry. H116 state aluminum plate, 0 state aluminum plate.

6061 aluminum plate is a heat-treatable alloy. After aging and solution treatment, it is in T6 state. In this state, the hardness can reach about 100HB. It is a good alloy for machining mechanical parts. When the hardness is 100HB, it is more useful in turning, milling, and grinding.

5083 vs 6061 Performance Differences
