Product Description

During the development process of lock, the key materials are also become diversified; and the common materials on market

include copper alloy, iron and zinc alloy. Depending on the excellent performance (easy processing, good corrosion resistance),

the market share of copper alloy reaches about 80%, and it is the first choice for high-class lock. However, key may be broken

off by careless user during use process, and the lock is scrapped. This problem is always the puzzle of the industry; if it is

directly replaced by materials with good toughness, key changes are unable to be processed. Through the continual efforts of

the team and the continual debugging in terms of material, equipment, mould, tool and process, this problem is finally solved via

one year's hard work, and the strength and toughness of key is improved by about 30%.


Test: bend for 3 times at 90°; unlocking may be normally performed after straightening; it shall not be broken after 5 times of bending at 90°
