The difference between 3105 aluminum plate and 3003 aluminum plate mainly lies in mechanical properties and chemical composition.
3105 aluminum plate has good rust resistance, good electrical conductivity, and electrical conductivity can reach 41%. 3105 aluminum plate has high plasticity in annealed state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, and good corrosion resistance. Good weldability and poor machinability. Application areas: room dividers, aluminum substrates for color coating, lamp caps, shutters, bottle caps, bottle stoppers, etc.
Chemical composition of 3105 aluminum plate
Aluminum Al: Balance Silicon Si: ≤0.6 Copper Cu: ≤0.3 Magnesium Mg: 0.2~0.8
Manganese Mn: 0.3～0.8 or Cr≤0.2 Titanium Ti: ≤0.1 Iron Fe: ≤0.7
Note: single: ≤0.05; total: ≤0.15
3003 aluminum plate is a typical Al-Mn alloy with good formability, corrosion resistance and weldability. The 3003 aluminum plate produced by Huawei Aluminum is often used to make power battery casings in lightweight vehicles, cooking utensils, food storage devices, tanks and bins on transportation equipment, metal sheet pressure vessels and pipes, etc.
3003 aluminum plate performance advantages:
1. Low plasticity and good corrosion resistance 2. Good formability, weldability and corrosion resistance 3. Good weldability.
Chemical composition of 3003 aluminum plate
Aluminum Al: Balance Silicon Si: ≤0.6 Copper Cu: 0.05~0.20
Manganese Mn: 1.0～1.5 Iron Fe: ≤0.7
Note: single: ≤0.05; total: ≤0.15
