What are the common materials of electronic password fingerprint lock and smart lock shell

In recent years, the smart home market has been in full swing. As the emerging electronic password fingerprint locks in smart homes, there are also many smart locks. Then, what materials are commonly used in electronic password fingerprint locks and smart lock shells?

 

First of all, the most widely used and the most cost-effective is the stainless steel smart lock shell. Stainless steel is also the earliest material for smart lock shells, but the surface treatment process is not selective;

 

Secondly, it is the zinc alloy die-casting smart lock shell. The surface treatment process of the zinc alloy die-casting code lock shell is diverse, with strong metal texture, sharp edges and corners, and of course its weight. Due to the high density of zinc alloy, the products produced are relatively heavy, giving consumers a very stable feeling, and are often favored by the majority of personal households and hotel club customers;

Then, it is the aluminum alloy die-casting smart lock shell. Due to the limitation of aluminum alloy die-casting technology, the aluminum alloy smart shell is less mature than the zinc alloy surface treatment process, especially the electroplating process. The zinc alloy is much more stable than the aluminum alloy. Common aluminum alloy smart lock shells only have fuel injection, electrophoresis, etc.;

Finally, there are some other new materials, such as plastic, wood, etc., but due to the limitation of the craft, the audience is very small, and few people pay attention and accept it.
