3003 aluminum sheet metal is a Al-Mn aluminum alloy. It has excellent workability and weldability properties for aluminum alloys, which is bout 20% stronger than pure aluminum.
The properties of 3003 aluminum sheet is deeply influenced by the processing technology besides its own composition.
Three Common Processing Technologies of 3003 Aluminium Sheet
1. Full Annealing
Heating at 390-430 ℃ and holding time is 30-120 min depending on the thickness of 3003 aluminum sheet, and then cooled with furnace to 300 ℃ with the speed of 30-50 ℃/h. After these steps, leave it for natural cooling.
2. Rapid Annealing
Heating at 350-370℃ and holding time is 30-120 min depending on the thickness of 3003 sheet aluminum. After these steps, leave it for natural cooling or water cooling.
3. Quenching and Aging
Quenching temperature is 500-510 ℃, air cooling; artificial aging is 95-105 ℃ for 3 hours; natural aging is 120 hours at room temperature.
