According to the product type, it can be divided into

3105 metal aluminum alloy belongs to AL-Mn 3000 series metal aluminum alloy. It has good rust resistance and good electrical conductivity. The aluminum content is 98%. Because 0.3% of copper is added to it, the conductivity can reach 41%; 3105 aluminum plate cannot Heat treatment is strengthened, so cold working methods are used to improve its mechanical properties: high plasticity in the annealed state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good weldability, and poor machinability.

3105 aluminum plate is a common grade of 3 series aluminum plate, with good rust resistance, good electrical conductivity (conductivity up to 40%), high plasticity in the annealed state, still good plasticity in the semi-cold work hardening, low plasticity in the cold work hardening, good weldability, poor machinability. 3105 aluminum plate is commonly used in room partitions, stalls, movable house panels, gutters and downspouts, thin plate forming and processing parts, bottle caps, corks, etc. Bottle caps, corks, etc.

Advantage of 3105 metal aluminum alloy

  • Good electrical conductivity, due to the addition of 0.3% copper element, the electrical conductivity can reach 41%;
  • Good anti-rust performance, applied to various bottle and can caps, can achieve the effect of long-term beautiful appearance of the bottle and can;
