Generally, the handle should be able to withstand a tensile force of more than 6 kilograms.

The handle lock can be divided into several types according to the material: space aluminum, stainless steel, copper die-casting, and zinc alloy. Space aluminum and stainless steel materials are advanced, and after surface treatment, they have a bright luster and a soft feel. Although corroded by sweat and moisture, they are not easy to fade or rust. Die-cast copper handle locks are relatively thick and affordable, while some low-quality zinc alloy handle locks are more prone to breakage when used. Due to the copper plating on the surface of the zinc alloy handle lock, it is not easy to distinguish it from copper die-cast handle locks when purchasing. You can use a screwdriver to repeatedly beat the bottom plate of the two types of handle locks. The brass colored one is a copper die-cast handle lock, while the silver white one is a zinc alloy handle lock.
