5052 aluminum sheet is commonly used aluminum-magnesium alloy material, it is the most commonly used material in the high-level aluminum recent years. Conventional temper are H32 and O. 5052 alloy is the most widely used rust-proof aluminum, this alloy is with high strength, especially with anti-fatigue strength, high plasticity and corrosion resistance, the plastic performance is good in the semi-functional cold hard.
5052 represents the product’s grade, with 5 at the beginning, representative of the product belongs to the aluminum-magnesium alloy products, and then according to chemical composition can see the product of magnesium alloy content of 2.2-2.8%, the density is 2.68. H32 on behalf of the product processing state H can be understood as incomplete annealing and processing hardening state, that is the product thorough annealing process, degradation of the hardness suitable for processing molding, and in order to avoid the product hardness is too soft, and the appropriate work hardening. The 32 on behalf of the modified product after a stable treatment hardness of 1/4. Usually the last number of the Arabic numerals and hardness values are directly related, such as H32 H34 H24 h18, the last Arabic numerals represent the hardness, in the same grade aluminum, the bigger Arabic numerals are, the higher the hardness is, such as H34 hardness is higher than H32, the most soft temper is O state, more suitable as a stretch material.
5052 aluminum sheet with the temper of H32 mans the aluminum-magnesium alloy with magnesium content is in the vicinity of 2.5%, after a stable treatment of incomplete annealing plus hardening processing state, the hardness is 1 / 4. Usually the product corrosion resistance is strong, the surface oxidation effect is good, bending ability is good, 90 degrees bending does not crack, is a typical sheet metal material, suitable for chassis cabinets and the classic materials of other products need to bend.
