The aluminium content of pure aluminum is the highest, generally can reach more than 99% pure aluminum to aluminium 1-series-based, including 1050,1060,1100, commonly used temper are H14, H18, H24, etc. The strength of aluminium can be changed by adding some other alloying elements because the density of pure aluminium is relatively small, close 2700kg / m³, the strength is not high, and further enhance the heat treatment, can change its strength. However, due to pure aluminium without other elements, the production process is relatively simple, its price is relatively cheap, is currently the most commonly used conventional industry.
