When it comes to marine aluminum plate, you will think of 5083 aluminum plate of 5-series aluminum magnesium alloy. At present, it is widely used in ships and yachts, and the use of aluminum plates in the middle and late stages accounts for the majority. H111, H112, H116 and H321 are commonly used aluminum materials by domestic and foreign ship manufacturers. What are the different states of 5083 marine aluminum plates?
The H state is the general state of aluminum products. The aluminum plates are subject to work hardening treatment, which improves the strength. The following states are subdivided into various states.
5083 h111 has been properly work hardened after final annealing, but it is applicable to products with lower work hardening degree than h11 state.
5083 H112 is applicable to free machining status and hot working products of hot rolled plates.
5083 H116 is applicable to products made of 5 series alloy with 4.0% magnesium content.
5083 H321 has good performance stability.
The main alloy element in 5083 alloy is magnesium, which has good corrosion resistance, weldability and medium strength. The excellent corrosion resistance makes 5083 alloy widely used in maritime applications such as ships, as well as automobile, aircraft welding parts, subway and light rail. Pressure vessels (such as liquid tankers, refrigerated vehicles, refrigerated containers), refrigeration devices, television towers, drilling equipment, transportation equipment, missile parts, armor, etc. that need strict fire protection.
