Wholesale Quality Aluminum Plate from China Factory

Aluminum plates are widely used in building curtain walls, decorative signage, shipbuilding and marine engineering, automotive sheet metal, rail transportation, mechanical structures, chassis enclosures, chemical storage tanks, thermal insulation and corrosion protection, and other fields. Chinese manufacturers stock a full range of mainstream grades, including 1060 pure aluminum sheets, 3003 rust-proof aluminum sheets, 5052/5754/5083 aluminum-magnesium rust-proof sheets, and 6061/6063 structural alloy sheets, covering various alloy states, complete specifications, custom cutting, and various deep processing services.

Alloy aluminum sheets include mainstream grades such as 3003, 5052, 5754, 5083, 6061, and 6063. Alloy aluminum sheets are lightweight, have high specific strength, and excellent resistance to rust and salt spray oxidation; they have good bending, stamping, and welding properties, and some grades can be heat-treated to improve strength. The surface is easy to anodize and spray-paint decoratively. It has good toughness and is not easily deformed, making it suitable for various fields such as construction, shipbuilding, automotive, machinery, and chemical industries. It comes in a full range of specifications and conditions, has a long service life, and offers excellent overall cost-effectiveness.

What is the difference between 6061 and 6063 aluminum plates?

What is the difference between O-temper and H-temper aluminum sheets? How to choose?

The O-temper is the annealed soft state, the softest state of aluminum sheet. It has excellent plasticity and ductility, making it extremely easy to bend, stamp, deep draw, and stretch. It is not prone to cracking during processing and has low internal stress. The disadvantages are low hardness, poor rigidity, and easy deformation, making it unsuitable for load-bearing structures and structural components requiring support and shaping.

The H-temper is the work-hardened state, hardened by cold rolling. It has high overall hardness, sufficient rigidity, and is not easily deformed. It has stronger support and load-bearing capacity, making it suitable for shaped panels and structural components. The disadvantage is reduced plasticity; the higher the hardness, the more difficult it is to bend, and large-angle bending can easily cause cracking.

A simple selection method: For applications requiring bending, punching, deep drawing, or complex sheet metal forming, choose the O temper. For decorative panels, chassis shells, structural supports, where a flat, non-deformable surface is required and bending is unnecessary, choose H32 or H34. The larger the number after the H, the higher the hardness and the more difficult it is to bend. Furthermore, for the same grade, the corrosion resistance of the O and H tempers is essentially the same, so differences in rust prevention do not need to be considered.
