Aluminum alloy profile of lock cylinder

Abstract

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.

Description

Technical field [0001] The invention relates to the field of lock cylinders, in particular to an aluminum alloy profile of the lock cylinder. Background technique [0002] At present, most of the material of lock cylinders on the market is copper. This is because copper has the characteristics of hard material, high strength, and easy cutting processing, which can meet the production and use requirements of lock cylinders. But in recent years, as the price of copper continues to rise, 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, the use of aluminum alloy to make the lock core can greatly reduce the cost. However, the existing aluminum alloy materials cannot meet the production requirements of the lock core. The material hardness is either too high or too low. The hardness is too high and cannot be directly extruded during product...

AI Technical Summary

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
