5052 aluminum plate is a conventional rust-proof aluminum alloy plate. It is divided into 5052 thin plate, 5052 medium and thick plate and 5052 thick plate according to specifications. It is divided into 5052-O aluminum plate, 5052-H112 aluminum plate and 5052-H32 aluminum plate according to the state. 5052-H34 aluminum plate, the above is the commonly used 5052 aluminum plate state.
5052 aluminum plate is widely used in fields such as ships, machinery, electronic appliances, chemicals, construction materials, decoration and decoration due to its good mechanical properties, cutting properties, and anodizing properties.
5052-H32 is the most commonly used 5052 aluminum plate state. H32 represents the processing status of the product. H can be understood as incomplete annealing and work hardening status, that is, the product has been annealed and the hardness has been reduced and is suitable for processing and forming. At the same time, in order to prevent the product from The hardness is too soft and it has been properly work hardened. 32 represents that the product has been stabilized and has a hardness of 1/4.
Hardness grade: Usually the Arabic numeral after H is directly related to the hardness value. For example, the Arabic numeral in H32, H34, H24, H18 represents the hardness. In the aluminum plate of the same trademark, the larger the Arabic numeral, the harder it is. High, for example, the hardness of H34 is higher than that of H32. If it is softer, it will directly become the 0 state, which is more suitable as a tensile material. Arabic numerals take even numbers, and the working terms of 2 4 6 8 become 1/4, 1/2, 3/4, and all hard.
In short, the aluminum-magnesium alloy plate 5052 aluminum plate is an aluminum-magnesium alloy with a magnesium alloy content of around 2.5%. It has been stabilized by incomplete annealing and hardening, and the hardness is 1/4. Generally, this product has strong corrosion resistance and a beautiful surface It has good oxidation effect, good bending ability, and does not crack when bent at 90 degrees. It is a typical sheet metal material, suitable for chassis cabinets and other classic materials that require bending processing.
