3000 Series Aluminum Alloys
3xxx Series Aluminum Alloys are manganese-alloyed grades (e.g., 3003, 3004) known for excellent corrosion resistance, moderate strength, and superior formability. With 1–1.5% manganese, these non-heat-treatable alloys achieve tensile strengths of 110–285 MPa, ideal for welded structures, fuel tanks, and architectural components. Their natural oxide layer resists harsh environments, including saltwater and chemicals (ASTM G67 compliant), while maintaining ductility (elongation: 10–25%) for deep drawing, bending, and stamping. Widely used in HVAC systems, food packaging, and automotive trim, 3xxx alloys offer lightweight durability (density: 2.73 g/cm³) and compatibility with anodizing or powder coating. Zhonglian Aluminum ensures precision via ISO-certified extrusion (±0.1mm tolerance) and surface treatments, meeting ASTM B209 and EN 573 standards for global industrial applications.
3000 Series Aluminum Alloys
It is the most widely used anti-rust aluminum. The strength of this alloy is not high (slightly higher than that of industrial pure aluminum) and can not be strengthened by heat treatment. Therefore, the cold processing method is used to improve its mechanical properties. It has high plasticity in the annealing state, good plasticity in semi-cold hardening, low plasticity in cold hardening, good corrosion resistance, good weldability, and poor chip cutting performance
3000 Series Aluminum Alloys
It is mainly used for low-load parts that require high plasticity and good weldability and work in liquid or gas medium. For example, electric heating pipes, oil tanks, gasoline or lubricating oil pipes, various liquid containers and other low-load parts made by deep drawing, wire rods are used to make rivets, and 3 series aluminum plates have good formability, fusion and corrosion resistance. It has good formability, high corrosion resistance, weldability, and slightly higher strength than 1 series of alloys, such as kitchenware, food and chemical product processing and storage devices, tanks and tanks for transporting liquid products, as well as various pressure vessels and pipes for sheet processing, general appliances, heat sinks, cosmetic carriers, photocopier rollers, and marine materials.
