Aluminum alloy section of lock cylinder

Abstract

The invention relates to an aluminum alloy section of a lock cylinder. The aluminum alloy section comprises, 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, 0.01-0.05 part of chromium, 0.2-0.28 part of zinc, 0.1-0.2 part of titanium, 0.06-0.08 part of nickel and 96.96-97.63 parts of aluminum. The aluminum alloy section of the lock cylinder has the advantages that the intensity and the hardness are relatively improved and are appropriate, and the production requirement of the lock cylinder is met; meanwhile, the ductility is good, and the punching requirement can be met; and in addition, the aluminum alloy section of the lock cylinder is very resistant to wearing and corrosion, and therefore the service life of the lock cylinder is accordingly prolonged.

Description

technical field [0001] The invention relates to the field of lock cylinders, in particular to an aluminum alloy profile of a lock cylinder. Background technique [0002] At present, most of the lock cylinders on the market are made of copper. This is because copper has the characteristics of hard material, high strength, and easy cutting and processing, which can meet the production and use requirements of lock cylinders. However, with the continuous rise of copper prices in recent years, the cost of lock cylinders has also risen sharply. In contrast, the price of aluminum is 1 / 4 to 1 / 3 of the price of copper, and the proportion of aluminum is only 1 / 3 of that of copper. Therefore, making the lock cylinder with aluminum alloy can greatly reduce the cost. However, the existing aluminum alloy materials cannot meet the production requirements of the lock cylinder. The hardness of the material is either too high or too low. If the hardness is too high, it cannot be directly ext...

Problems solved by technology

However, the existing aluminum alloy materials cannot meet the production requirements of the lock cylinder. The hardness of the material is either too high or too low. If the hardness is too high, it cannot be directly extruded during production, and if the hardness is too low, it cannot meet the processing of turning and drilling. Require

[0003] For above-mentioned phenomenon, Chinese Patent No. is 200810235338.X to propose a kind of aluminum alloy lock core, and the parts by weight of its composition is as follows: silicon<0.4 part; Iron<0.4 part; Magnesium 1.0~1.3 part; Copper 1.0~12 part ; 0.3-0.4 parts of manganese; 0.1-0.15 parts of chromium; 3.0-3.5 parts of zinc; 0.2-0.25 parts of titanium; the balance is aluminum; A lot of cost, but the wear and corrosion resistance of this lock cylinder is relatively poor
