Aluminum alloy profile of lock cylinder

The invention relates to an aluminum alloy profile of a lock cylinder. The aluminum alloy profile is prepared from, by weight, 0.8-1.0 part of silicon, 0.1-0.3 part of iron, 0.7-0.9 part of magnesium,0.1-0.13 part of copper, 0.2-0.3 part of manganese, 0.01-0.03 part of chrome, 0.2-0.28 part of zinc, 0.1-0.2 part of titanium, 0.06-0.08 part of nickel, 0.01-0.03 part of boron and 96.96-97.63 partsof aluminum. The aluminum alloy profile of the lock cylinder has the advantages that the strength and hardness are relatively improved and moderate and meet production requirements of the lock cylinder, meanwhile, malleability is good, and punching requirements can be met. In addition, the aluminum alloy profile of the lock cylinder is extremely resistant to wear and corrosion, and therefore the service life of the lock cylinder is prolonged. 本发明涉及种锁芯的铝合金型材，所述铝合金型材的组成成份的重量份数如下：硅0.8-1.0份；铁0.1-0.3份；镁0.7-0.9份；铜0.1-0.13份；锰0.2-0.3份；铬0.01-0.03份；锌0.2-0.28份；钛0.1-0.2份；镍0.06-0.08份；硼0.01-0.03份；铝96.96-97.63份。本发明的优点在于：本发明的锁芯的铝合金型材其
