Key Factors to Confirm Before Bulk Aluminum Ordering

1.Working environment: Indoor dry / urban rain exposure / coastal salt fog / chemical acid & alkali corrosion (decides 3xxx / 5xxx marine alloy)

2.Processing requirement: Deep stamping (choose O soft temper) / bending forming (H32/H22) / rigid flat panel (H34/H18/T6)

3.Surface demand: Mill finish only / anodizing / PVDF color coating / food contact surface

4.Target industry certification: CE construction, DNV marine, RoHS electronics, FDA food contact, AS9100 aerospace

5.Size specification: Custom thickness, width, slitting service, cut-to-size blanks or jumbo rolls

How to Pick The Right Temper For Your Aluminum Material

• O temper: Fully annealed soft state, maximum ductility for deep drawing, battery shells, complex stamped decorative parts

• H series (cold hardening): H14/H22 for moderate forming; H32/H34 for anti-rust structural use; H18 full hard for rigid flat substrates

• T series (heat treatment): T6 artificial aging for peak strength structural aluminum plate (6005, 6061, 7075)
