The 3003 series aluminum plate is a commonly used product in the aluminum-manganese alloy series. Thanks to the manganese alloy element, this product has excellent rust-proof properties and is also known as rust-proof aluminum.
The strength is about 10% higher than 1100, and the formability, the solubility, and the corrosion resistance are good. It is used to process parts that require good formability, high corrosion resistance, or require both these properties and work with higher strength than 1XXX alloys, such as kitchen utensils, food and chemical products. Storage device, tanks and tanks for transporting liquid products, various pressure vessels and pipes for processing of thin plates, general radiators, heat sinks, cosmetic plates, photocopier drums, marine materials.
Characteristics of 3003 aluminum plate:
3003 is an AL-Mn alloy, which is the most widely used rust-proof aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum), and it can not be heat-treated. Therefore, cold working method is used to improve its mechanical properties: It has high plasticity in the annealed state, good plasticity in semi-cold hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability. Uses are mainly used for low load parts requiring high plasticity and good weldability in liquid or gaseous media, such as mailboxes, gasoline or lube oil pipes, various liquid containers and other small load parts made with deep drawing: Wire is used to make rivets.
3003 aluminum plate application range:
3003 aluminum plate is often used in wet environment such as outer packaging, mechanical parts, refrigerator, air conditioning ventilation duct, etc., the product has good anti-rust ability.
3003 aluminum plates are commonly used in ships, ships, vehicle materials, automotive and aircraft welded parts, pressure vessels requiring strict fire protection, refrigeration equipment, television towers, drilling equipment, transportation equipment, missile components, armor, etc. 3003 aluminum plate density formula and calculation is: length mm * width mm * height mm * 0.0000062

3003 aluminum plate heat treatment process:
1) Complete annealing: heating 390 ~ 430 ° C; with the effective thickness of the material, the holding time is 30 ~ 120min; with the temperature of 30 ~ 50 ° C / h with the furnace cooled to 300 ° C, and then air cooled.
2) Rapid annealing: heating 350 ~ 370 ° C; with the effective thickness of the material, holding time 30 ~ 120min; empty or water cooled.
3) Quenching and aging: quenching 500~510°C, air cooling; artificial aging 95~105°C, 3h, air cooling; natural aging room temperature 120h
Chemical properties of 3003 aluminum plate:
Corrosion resistance: 3003 aluminum plate has good corrosion resistance, close to the corrosion resistance of industrial pure aluminum, and has good corrosion resistance to atmospheric, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt aqueous solution, etc. The corrosion resistance in dilute acid is also very good.
In the cold deformation state, the 3003 aluminum alloy has a tendency to peel off and corrode, and the larger the deformation, the more severe the peeling. Since the color is not uniform after anodization, the anodizing treatment is generally not performed.
