Classification of Aluminum Sheet/Plate

According to alloy composition is divided into:
① High purity aluminum plate (the purity above 99.9%)

② Pure aluminum plate
(ingredients made from pure aluminium rolling)
③ Alloy aluminum plate
(composed of aluminum alloy usually with AL and CU, AL and MN, AL and SI, AL and MG etc)
④ Composite aluminum plate or brazing plate
(a variety of material compound for special purposes )


Feartures Of 3000 series

3000 series aluminum sheet is approx 20% stronger than the 1000 series, has great workability and may be deep drawn, spun, welded or brazed. The 3000series aluminum sheet is widely used for general purposes. The Alloy are including the AA3003, AA3004, AA3005, AA3102, AA3105, Temper O, H14, H18, H24, H26, H111, H112, F, From thickness 0.2mm-350mm, width 500mm-2300mm, length 500mm-110000mm. With Plain, five bar, stucco, diamond, or mirror surface process, Or coated with PE, PVDF, BRUSH etc. There is (CC) cold rolling and (DC) hot rolling Line.

Application Of 3000 series

3003 Aluminum Sheet Approx. 20% higher strength than the 1100 series, but retaining an excellent workability rating. May show some slight discoloration when anodized, but reacts well to mechanical and organic finishings. 3003 is easily welded and brazed, but solder is limited to the torch method. Like 1100, tends to be "gummy" when machined. Non-heat treatable.Typical applications include food and chemical equipment, appliance components, truck and trailer roofing, heat exchangers, and lawn furniture components.


Temper Description

As fabricated (no mechanical property limits specified)
Annealed - products achieving the required annealed properties after hot forming processes may be designated as O temper.
Slightly strain-hardened from working at an elevated temperature from a limited amount of cold work (mechanical property limits specified).
Solution heat-treated and naturally aged.
Cooled from an elavated temperature shaping process and then artificially aged.
Solution heat-treated and then artificially aged.
Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate, 1% to 3% for rolled or cold finished rod and bar, 1% to 5% for hand or ring forging and rolled ring) and then artificially aged. The products receive no further straightening after stretching.
