Aluminum Sheet 3003 Has Excellent Anti-rust Properties
- Sep 28, 2017 -

3003 series aluminum plate is a commonly used product of aluminum and manganese alloy series. As a result of the manganese alloy elements, which products have excellent anti-rust properties, also known as rust-proof aluminum.

characteristic:

3003 for the AL-Mn alloy, is the most widely used a rust-proof aluminum, the strength of this alloy is not high (slightly higher than the industrial aluminum), can not heat treatment to strengthen, so the use of cold processing methods to improve its mechanical properties: In the annealing state has a high plasticity, semi-cold hardening when the plastic is still good, cold hardening when the plastic low, good corrosion resistance, good weldability, cutting performance. Uses are mainly used for low load parts requiring high plasticity and good weldability, working in liquid or gaseous media, such as mailboxes, petrol or lubricating oil conduits, various liquid containers and other small load parts made with deep drawing: Wire used to make rivets.

Scope of application:

The product is often used in the packaging, mechanical parts, refrigerators, air conditioning and ventilation pipes and other humid environment, the product has a good anti-rust ability.

3003 aluminum plate commonly used in ships, ships, vehicle timber, automotive and aircraft plate welding parts, need to strictly fire pressure vessels, refrigeration equipment, television towers, drilling equipment, transportation equipment, missile components, armor and so on.

3003 aluminum plate density formula and calculated as: length mm * width mm * high mm * 0.00000272.

Mechanical properties:

Tensile strength σb (MPa)) 120-160

Conditional yield strength σ0.2 (MPa)) ≥85

Sample size: all wall thickness

Note: longitudinal mechanical properties of pipe at room temperature

Aluminum plate with the national standard (GB / T 3880-2006), applicable to aluminum alloy strip material uniform standards.

Heat treatment process:

1) complete annealing: heating 390 ~ 430 ℃; with the effective thickness of the material is different, holding time 30 ~ 120min; 30 ~ 50 ℃ / h speed with the furnace cooled to 300 ℃, and then air-cooled.

2) rapid annealing: heating 350 ~ 370 ℃; with the effective thickness of the material, holding time 30 ~ 120min; empty or water-cooled.

3) quenching and aging: quenching 500 ~ 510 ℃, air cooling; artificial aging 95 ~ 105 ℃, 3h, air cooling; natural aging room temperature 120h

Aluminum alloy Calculate the weight of aluminum (kg) = 0.0000029 × thick × width × length aluminum tube weight (kg) = 0.0000029 × wall thickness × (outer diameter - wall thickness) × length aluminum rod weight formula (kg) = 0.0000029 × radius × diameter 60mm spot size 6061 plate spot Specifications: 0.3mm-350mm (thickness) 6061 bar Spot Specifications: 3.0mm-500mm (diameter) 6061 wire spot Specifications: 0.1mm-20mm (wire diameter)

3003 aluminum chemical properties:

Corrosion resistance: 3003 Aluminum corrosion resistance is very good, close to the corrosion resistance of industrial pure aluminum, the atmosphere, fresh water, sea water, food, organic acids, gasoline, neutral inorganic salt solution, etc. have good corrosion resistance, The corrosion resistance in the dilute acid is also good.

In the cold deformation state, 3003 aluminum alloy has a tendency to peel corrosion, the greater the deformation, the more serious stripping. As the anodic oxidation of the color is not uniform, it is generally not anodized.
