Due to the lighter weight of aluminium, aluminum strip ceiling avoids the need for expensive support structures. Haeomi aluminum strip has rich colors, providing greater design freedom for shaping individual solutions. It also enables a reduction in material thickness by 10 pcs percent, still maintaining the same formability and stiffness.
3003 aluminum strip is a commonly used aluminum-manganese alloy strip used in ceiling. Because of the aluminum and manganese elements, this 3003 aluminum strip is also called rust-proof aluminum strip. However, the specific gravity of 3003 aluminum strip is larger than that of 1060 aluminum.
The hardness and strength of 3003 aluminum strip are about 10% higher than that of 1100 aluminum. 3003 aluminium strip ceiling also have good solubility, formability, and excellent corrosion resistance, which has became a favored product in ceiling field.
Melting Point：
Around 650-680 degrees Celsius
Hardness：
The strength is about 10% higher than 1100.
Density：
2.72
Elongation：
The elongation of 3003 aluminum strip is generally not as good as that of 1060 aluminum.
1. Complete annealing: heating at 390-430°C; the holding time is 30-120min depending on the effective thickness of the material; cooling to 300°C with the furnace at a rate of 30-50°C/h, and then air cooling.
2. Rapid annealing: heating at 350～370℃; holding time 30～120min depending on the effective thickness of the material; air or water cooling.
3. Quenching and aging: quenching at 500～510℃, air cooling; artificial aging at 95～105℃, 3h, air cooling; natural aging at room temperature for 120h.
