3A21 Aluminum Sheet Product Introduction
3A21 aluminum sheet is also a typical 3 series Al-Mn antirust alloy, 3A21 aluminum alloy has the characteristics of excellent corrosion resistance, good formability and weldability, and appropriate strength, etc., so it is widely used in both these properties and the conditions requiring higher strength than the 1-series alloy, or the low-load parts working in liquid and gas medium, etc.
Yongsheng Aluminum can customize processing according to customer needs. All our products are manufactured with advanced equipment and strict QC procedures in order to insures every product's high quality. Sample can be provided as your requirements for free.
Yongsheng 3A21 aluminum sheet price is reasonable and very competitive. We also offer 3104 aluminum sheet,3105 aluminum sheet,3M03 aluminum sheet, and other types for you to choose.
3A21 Aluminum Sheet
3A21 Aluminum Sheet Advantages
1. Excellent Corrosion Resistance. The 3A21 aluminum sheet is close to the corrosion resistance of industrial pure aluminum, has good corrosion resistance to atmosphere, fresh water, seawater and some acids, etc.
2. Better Plasticity. The plasticity of 3A21 aluminum alloy is very high in the annealing state, good in the case of semi-cold hardening, and low in the case of cold hardening.
3. Good Weldability. 3A21 aluminum sheet has good spot welding, gas welding, argon arc welding and other welding effects.
4. Mechnical Properties. 3A21 aluminum sheet tensile strength σb (MPa) is 120-160, conditional yield strength σ0.2 (MPa)≥8, elongation δ10≤2%.

3A21 Aluminum Sheet Application
1. Low load parts for working in liquid or gaseous medium. Such as Oil tanks, Gasoline, Lubricating oil pipes, Various liquid containers, and other small load parts made by deep drawing.
2. For use under conditions of higher strength than 1 series alloy. Such as Kitchen utensils, Food/chemical products processing and storage equipment, Transport tank of liquid products, Thin plate for all kinds of pressure vessels and pipe, Brazed plate-type heat exchanger, Insulation equipment, Cosmetic board, Photocopying machine drum, Marine tread plate. As for wire is used for rivets.
3A21 Aluminum Sheet Application
3A21 Heat Treatment
Homogenization annealing
Heating 510 ~ 520 °C; heat preservation 4 ~ 6h; air cooling.
Rapid annealing
Heating 350 ~ 410 °C, holding time 30 ~ 120 min with different effective thickness, air or water cooling.
High temperature annealing
Heating 350 ~ 500 °C, holding time 10 ~ 30 min when finished product thickness ≥6mm. Product thickness < 6 mm, until the heat through; air-cooled.
Low temperature annealing
Heating 250 ~ 300 °C; holding time 1 ~ 3h; air or water cooling.
Aluminum Sheet Packaging
Yongsheng aluminum sheet is placed on a wooden pallet or wooden box, wrapped perfectly with waterproof craft paper, and then fixed with a narrow strip of iron.
Usually, we have six layers of packing: put on wooden supports and put desiccant, wrap moisture proof film, wrap the plastic film, wrap the moisture-proof cotton, wrap the plastic moisture proof film again and pack it with cardboard
