Product Description:Pre-painted aluminum coils refer to aluminum coils that have been coated with a layer of protective lacquer or paint. This coating serves multiple purposes, including enhancing the aesthetic appearance of the aluminum, providing protection against corrosion, and offering additional durability. The lacquer is applied to the surface of the aluminum coil through a coating process.Series 3 aluminum alloys (such as 3003, 3004, 3105, etc.) are non-heat-treatable strengthened aluminum alloys with manganese (Mn) as the main alloying element. They have excellent formability, corrosion resistance, and moderate strength, and are widely used abroad in fields such as construction, packaging, and transportation. Below are their detailed uses, advantages, and typical application scenarios:
3003: Al + 1.0%-1.5% Mn + trace Cu/Fe/Si (most commonly used).
3004: Al + 1.0%-1.5% Mn + 0.8%-1.3% Mg (higher strength, for beverage cans).
3105: Al + 0.3%-0.8% Mn + 0.2%-0.8% Mg (for building drainage systems).
Mechanical properties (take 3003 as an example):
Tensile strength:
O state (annealed): 110-150 MPa
H14 state (semi-hard): 160-200 MPa
Elongation: O state can reach 20%-30%, suitable for deep drawing processing.
Key Benefits:
Corrosion resistance: Manganese elements form a dense oxide film, which is resistant to moisture, industrial atmosphere, and freshwater corrosion.
Formability: Excellent cold workability, can be stamped, bent, stretched.
Weldability: Suitable for TIG/MIG/resistance welding, and the weld strength is stable.
Cost-effective: The price is lower than that of the 5 series (e.g. 5052) and the strength is better than that of the 1 series (e.g. 1100).
Main applications and typical application scenarios:
| field | Specific uses | Examples of application scenarios |
| Construction industry | Roof panels, wall panels, gutters, ceilings | The roof of a commercial building in the United States (3003 H14), the exterior wall cladding of a light steel villa in Japan |
| packaging industry | Beverage cans (3004), food containers, chemical barrels | Coca-Cola cans (alloy 3004), European beer keg lining |
| Transportation | Car fuel tanks, truck compartment boards, ship deck decorations | German automobile fuel tank (3003 anti-rust), Australian cargo ship protective plate |
| Appliance manufacturing | Refrigerator liners, air conditioner radiators, oven shells | Samsung refrigerator evaporator (3003), American household radiator |
| Industrial equipment | Storage tanks, heat exchangers, conveying pipelines | Canadian chemical storage tank (acid and alkali resistance), Middle East desalination equipment |
