Aluminium Wire Rods
7000 series aluminium rods are known for their exceptional strength and hardness, primarily due to zinc being the major alloying element. They exhibit good heat treatability and are widely used in aerospace and automotive applications, as well as sports equipment owing to their superior mechanical properties.
7000 series aluminium alloys are primarily alloyed with zinc, providing exceptional strength and toughness. Their typical chemical composition includes: (Al): 87.12% to 89.62%, (Mg): 2.10% to 2.90%, (Zn): 5.10% to 6.10%, (Cu): 1.20% to 2.0%, (Cr): 0.18 to 0.28%, (Fe): Maximum 0.5%, (Si): Maximum 0.4%, (Mn): Maximum 0.3%, Residuals: Maximum 0.15%
