4.Production process
Precise Batching and Melting: Mix aluminum, magnesium, chromium and other alloying elements according to chemical composition ratio, put into power frequency or intermediate frequency furnace for high-temperature melting, and use online refining technology to remove hydrogen and impurities to ensure alloy purity and uniformity
Semi-continuous Casting: Pour the refined aluminum alloy liquid into flat ingots through a semi-continuous casting machine, control the cooling rate, avoid casting defects, and ensure dense internal structure of the ingots
Homogenization Heat Treatment: Put the ingots into a heat treatment furnace, keep warm at 450-500℃ for a certain time, eliminate composition segregation, optimize grain structure, and improve subsequent processing performance
Hot Rolling Billet: Heat the ingots to 400-480℃ for hot rolling, gradually reduce thickness through multiple passes of rolling, obtain hot-rolled coils of a certain thickness, refine grains and improve mechanical properties
Cold Rolling Finishing: Perform multiple passes of cold rolling on hot-rolled plates at room temperature, strictly control rolling speed and reduction, roll to target thickness, and ensure dimensional accuracy and surface finish
Finished Product Heat Treatment: Conduct solution treatment or stabilization annealing as needed, temper to common states such as H32 and H34 to ensure stable mechanical properties of the product; finally, edge trimming, flattening, fixed-length cutting, inspection and packaging for warehousing
5.FAQ
Q1:What are the common tempers of 5052 aluminum plate? What are the differences in applicable scenarios of different tempers?
A1:Common tempers are O, H32, H34. Temper O is soft with excellent ductility, suitable for high-precision forming processes such as deep drawing and complex bending; Temper H32 is half-hard with moderate strength, suitable for conventional structural parts such as building decoration and home appliance housings; Temper H34 is full-hard with the highest strength, suitable for high-strength demand scenarios such as pressure vessels and automobile structural parts.
Q2:What surface treatments can be applied to 5052 aluminum plate? Which treatment method is most suitable for outdoor scenarios?
A2:Surface treatments such as anodizing, PVDF coating, polyester coating, sandblasting and wire drawing are available. PVDF coating is preferred for outdoor scenarios, which has excellent UV resistance and aging resistance, strong coating adhesion, and can extend the outdoor service life to more than 20 years; anodizing + sealing treatment can be used in marine environments to further improve corrosion resistance.
Q3:What should be noted when storing and transporting 5052 aluminum plate?
A3:Storage should be in a dry, ventilated, rainproof and moisture-proof warehouse, avoiding coexistence with corrosive substances such as acids, alkalis and salts; sheets should be stacked flat with a stacking height not exceeding 1.5 meters to prevent compression deformation of the bottom sheets; during transportation, waterproof tarpaulin should be used for covering to avoid rain and sun exposure, and light loading and unloading to prevent collision and scratch. Sheets of different tempers and specifications should be stored and transported separately to avoid mixing.
Q4:Can 5052 aluminum plate be used for food contact containers?
A4:Yes, but food-grade 5052 aluminum plate should be selected. Food-grade products need to strictly control the content of alloy impurities, adopt food-grade processing technology in the production process, select non-toxic and environmentally friendly coatings for surface treatment, and can be used only after passing the test and meeting the standard of GB 4806.2-2016 (Aluminum and aluminum alloy products for food contact). Regular industrial-grade 5052 aluminum plate is not recommended for direct contact with food.
