Some people may ask why the door locks should choose zinc alloy material. There are stainless steel and copper on the market. These manufacturers are everywhere. I don’t know if the zinc alloy lock is durable, I don’t know if the zinc alloy lock is nice, I don’t know why I choose CAUSTE. With these questions, the following small series will give you a general introduction to the hardware material.


Indeed, from the price point of view, the price of stainless steel is relatively civilian, because stainless steel door locks are rarely electric-plated, mainly based on primary colors and polishing. In this case, the cost of the stainless steel door lock is much lower. And stainless steel materials are relatively cheap, the cost of lock is also very low, many people will choose to buy.

And copper? Anyone with hardware knowledge knows that the price of copper is the highest, and even the wires are made of copper. Otherwise, why are so many people holding wires? Coughing ~ off topic, but this fully illustrates the value of copper, so the cost of making door locks by copper is relatively high. The copper material is soft, so it can be formed into various complicated appearances by die-casting. The door locks that are made seem to be more classical and suitable for the high-end places such as giants door, hotel door and villas doors.

The main event came, zinc alloy door locks, zinc alloy materials, the price is a little more expensive than stainless steel, but it has the characteristics of stainless steel and copper , the main features are:

1. Relatively large weight.

2. The casting performance is good, and the precision parts with thin and thin walls can be die-casted, and the surface of the casting is smooth.

3. Surface treatment: electroplating, spraying, painting, polishing, grinding, etc.

4. No iron is absorbed during melting and die casting, no corrosion is applied, and no mold is sticked.

5. Has good mechanical properties and wear resistance at room temperature.

6. Low melting point, melting at 385 ° C, easy to die-cast.


Therefore, the door lock made of zinc alloy is not only beautiful but also durable. The coloring effect after plating treatment is quite good, the price is also mid-range, or is acceptable to many families. It has stainless steel anti-corrosion and makes like copper door lock. The effect, isn’t that what you want?
