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% ไอเอซีเอส (International Annealed Copper Standard)
• Resistivity 2.66×10-8Ωm (ohm meter) (99.9%อัล);

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, กรดไฮโดรคลอริก, alkali and salt.

3. Pure aluminum features

• light in mass
• การนำไฟฟ้าที่ดีเยี่ยม, heat transfer and plastic deformation properties
• Good corrosion resistance in the atmosphere
• Low strength is not suitable for structural materials
