Industrial Pure Aluminum
1. Pure aluminum physical properties
- Melting point 660.24℃; density 2.7×103kg/m3;
- Face-centered cubic lattice a=0.4049nm; atomic diameter 0.286 nm
- Relative conductivity 62% IACS (International Annealed Copper Standard)
- Resistivity 2.66×10-8Ωm (ohm meter) (99.9%آل);
2. Pure aluminum chemical properties
- The chemical activity of aluminum is extremely high, the standard electrode potential (-1.67 volts).
- Aluminum forms a 5-10nm thick Al2O3 protective film on the surface in the air, which is corrosion-resistant in the atmosphere.
- It has extremely high stability in concentrated nitric acid, and hardly reacts with organic acids and food.
- Unstable in sulfuric acid, حامض الهيدروكلوريك, alkali and salt.
3. Pure aluminum features
- light in mass
- Excellent electrical conductivity, heat transfer and plastic deformation properties
- Good corrosion resistance in the atmosphere
- Low strength is not suitable for structural materials
