stainless steel

High strength, strong corrosion resistance, no discoloration, is the best lock material, but the forging performance is not good, the style and color of stainless steel door locks are relatively simple.


Excellent mechanical properties and bright color. Generally used to make European high-end door locks, the price and grade are relatively high.

Zinc alloy

Sturdy and wear-resistant, corrosion-resistant and other properties, and easier to cast, can design a lot of styles and patterns, the current hot locks on the market are many zinc alloy materials.

Aluminum or aluminum alloy

Mainly space aluminum, this type of door lock design is generally relatively simple, no pattern design, less application.


The strength is good, the cost is low, and the plating layer is generally applied, but it is easy to rust.
