What is 3000 series aluminum?

The 3000 series aluminum is a typical Al-Mn antirust alloy. The addition of the alloy component Mn increases the strength slightly while maintaining the excellent workability and corrosion resistance of pure aluminum. The 3000 series aluminum sheet is a non-heat-treated alloy and cannot be strengthened by heat treatment, so the conventional cold working method can improve its mechanical properties. In addition, 3000 series aluminum sheet has excellent weldability, formability and other advantages, and has become a popular and economical choice for “home appliance components”. In addition to the commonly used specifications, Mingtai Aluminum can also produce 3000 series ultra-wide and ultra-thick aluminum plates with internal stress relief and no deformation during cutting, and the width is 2650mm, the thickness is 500mm. So Mingtai becomes one of the few manufacturers in China that can produce ultra-wide and ultra-thick aluminum plates.

The fetures of 3000 series aluminum

1. Corrosion Resistance.3000 series aluminum sheet has good corrosion resistance, which is close to the corrosion resistance of industrial pure aluminum. It can effectively resist the corrosion of atmosphere, fresh water, sea water, food, organic acids, gasoline, neutral inorganic salt solution, and dilute acids.

2. High Plasticity. In the annealed temper, the plasticity of the 3000 series aluminum sheet is very high. In the case of semi-cold work hardening, its plasticity is still good, and its plasticity is low when it is cold worked. Good weldability and poor machinability.

3. Weak Resistance to Peeling Corrosion. In the cold deformed state, the3000 series aluminum sheet has a tendency to peel and corrode. The larger the deformation is, the more severe the peeling is. Because the color is not uniform after anodizing, anodizing is generally not performed.

The application of 3000 series aluminum

Typical uses of 3000 series aluminum sheet: heat sinks, radiators, power battery enclosures, automotive heat shields, fuel tanks, water tanks, automotive skid plates, battery explosion-proof valves, battery covers, automotive interiors, signs, cans, medical equipment, etc.

Typical use of Ultra-wide 3000 series aluminum sheet: bus skins, silos, antenna pan materials, wide curtain wall panels, wide roof panels, etc.

Use of 3000 series aluminum sheet foil coils: honeycomb core aluminum foil, electronic foil, honeycomb material, lunch box material, container foil, etc.
