Aluminum alloy 5083 has different physical and mechanical properties in the O and H111 tempers, and these property differences determine their suitability for different application scenarios.
The following is a detailed comparison of 5083-O and 5083-H111:
- Alloy Composition and Basic Properties
5083 Aluminum Alloy: Belongs to the Al-Mg system of alloys, the main alloying element is magnesium, and therefore has good corrosion resistance, weldability and moderate strength. This alloy is usually used in the need for high corrosion resistance, good weldability and medium strength occasions, such as ships, automobiles and aircraft plate welding parts.
- The difference between O temper and H111 temper
5083-O temper:
– Temper description: O temper indicates that the 5083 aluminum plate has been completely annealed to the softest state.
– Mechanical properties: due to the complete annealing, 5083-O aluminum plate strength and hardness is relatively low, but plasticity and ductility is better.
– Processing properties: easy to carry out bending, stamping and other forming processes, not easy to produce cracks or fractures.
– Application Scenario: Suitable for occasions that do not require high strength, but need good formability and corrosion resistance, such as aluminum alloy street light poles, auto body panels, etc.
5083-H111 temper:
– State Description: The H111 temper indicates that the 5083 aluminum plate has been work-hardened and partially annealed to remove stress and improve stability.
– Mechanical Properties: Relative to the O temper, the strength and hardness of aluminum plate in the 5083-H111 temper have been improved, but still maintains good plasticity and ductility.
– Machinability: Although not as easy to bend as the O-state, it can still be formed to a certain extent. At the same time, due to the improvement of hardness and strength, H111 aluminum plate has better stability when subjected to external forces.
– Application Scenario: Suitable for occasions that require a certain degree of strength and hardness, and at the same time require good corrosion resistance and weldability, such as ship structural parts, automobile fuel tanks and so on.
- The summary of 5083 o vs h111:
– Selection basis: when choosing 5083 aluminum alloy, you should select the appropriate material state according to the needs of specific application scenarios. If good formability and corrosion resistance are required, and the requirement for strength is not high, 5083-O aluminum can be selected; if a certain degree of strength and hardness is required, and at the same time, good corrosion resistance and weldability are required, 5083-H111 aluminum can be selected.
– Performance Comparison: From the mechanical properties, the strength and hardness of 5083-H111 aluminum is higher than 5083-O aluminum, but the plasticity and ductility may be a little inferior to O state. From the point of view of processing performance, 5083-O aluminum is easier for bending, stamping and other molding process.
In summary, there are significant differences between aluminum 5083-O and 5083-H111 in terms of alloy composition, mechanical properties, processing performance and application scenarios. Therefore, the selection needs to be weighed and chosen according to specific needs.
