Physical properties
Metal silvery-white, light, density - 2.7 g / cm ³, the melting temperature of aluminum at the Technical - 658 ° C, a high-purity aluminum - 660 ° C, the latent heat of fusion - 390 kJ / kg, the boiling temperature - 2500 ° C, the latent heat of evaporation - 10.53 MJ / kg, tensile strength cast aluminum - 10-12 kg / mm ², deformable - 18-25 kg / mm ², alloys - 38-42 kg / mm ².
Brinell hardness - 24-32 kg / mm ², high plasticity: the technical - 35%, from net - 50%, laminate and even foil.
Aluminium has high electrical conductivity (0.0265 IMEC * m) and thermal conductivity (1.24 * 10-3 W / (m * K)), 65% of the electrical conductivity of copper, has a high svetootrazhatelnoy ability. Moderate paramagnet. Temperature coefficient of linear expansion of 24.58 * 10-6 K-1 (20-200 ° C).
Aluminum forms alloys with almost all metals. The most known alloys with copper and magnesium (anodized aluminum) and silicon (silumin).
