Fingerprint locks generally consist of two parts: electronic identification and control, and mechanical linkage system. The uniqueness and non-reproducibility of fingerprints determines that the fingerprint lock is the most secure lock type among all locks at present. What are the materials used in fingerprint door locks and what are the differences between different materials? This article will briefly introduce you.
Fingerprint door lock materials mainly include: space aluminum materials, zinc alloy materials, stainless steel materials, stainless steel materials, etc.
Space aluminum material
Space aluminum is an aluminum-magnesium alloy that has undergone special treatment such as high-temperature oxidation, which is easy to process, but has low strength and poor impact resistance. Because of its soft texture, it is also easy to deform. The color is hard and monotonous, and the style is relatively simple. Space aluminum material itself is low in value, easy to oxidize, has a short lifespan, and its fire protection function is not optimistic.
Zinc alloy material
Zinc alloy is easy to cast and process, can be electroplated, sprayed, painted, polished, polished and other surface treatments, and the development cost is low. Zinc alloy also has good mechanical properties and wear resistance at room temperature. There are many styles of smart locks of this kind of material, and there are more choices of surface colors, which can meet a variety of home decoration needs.
Stainless iron material
The so-called “stainless iron” refers to the reclaimed scrap iron, lead, steel, etc., which is processed by the secondary furnace and processed by demagnetization. Stainless iron contains chromium but not nickel, while stainless steel contains both chromium and nickel. Nickel is a relatively stable element, so the corrosion resistance of stainless steel is naturally much stronger than that of stainless iron. However, because nickel is more expensive, the cost of stainless steel is higher than that of stainless iron. Coupled with the difference in corrosion resistance, the price of stainless steel is 1/4 to 1/3 higher than that of stainless iron.
Stainless steel material
Stainless steel has good strength, strong corrosion resistance and good color stability. It is the best material for making locks. However, there are many types of stainless steel, mainly divided into ferrite and austenite. Because of the high chromium content, ferritic stainless steel has better corrosion resistance and oxidation resistance, but its mechanical and technological properties are poor. After a long time, it will rust in a bad environment. Only austenitic stainless steel will not Rusty.
A good fingerprint lock, the panel is generally made of zinc alloy and stainless steel, integrated manufacturing, strong structure, strong resistance to destruction. Consumers must choose carefully and be careful of being deceived.
We first look at the function of the lock body. It is mainly a mechanical device that faithfully executes the opening and closing of the lock. It is one of the main guarantors of safety and durability. It is also one of the core parts of the smart door lock. Its material requirements It is to be durable and strong. Therefore, the main materials of the current lock body are mainly iron and stainless steel, and some zinc alloys. Copper is mainly used for the lock tongue, and copper is rarely used for internal parts. All stainless steel is expensive and difficult to process, but the price is very expensive. The generally applied processes are mainly precision casting, stretching, cold forging, etc.; iron is the most cost-effective among the lock bodies, so the current mainstream lock bodies are used Stainless steel is used for durable parts, such as bolts and square rod transmission structural parts. These are made of stainless steel to increase durability and reliability. Other parts use iron to reduce costs. The application process is basically the same as stainless steel, and some are low. All of them are made of iron or stainless iron, and even low-end powder metallurgy is used in the bolt processing technology (the quality of high-end powder metallurgy parts is very good, and the cost is also very high. Some stainless steel also uses powder metallurgy, so it will be easy to process. Some), the cost is low, but the reliability and durability are slightly worse.
This is currently the most concerned by many consumers, and it is also the most discussed. Generally speaking, the material of smart door locks mostly refers to the material of the panel, which can also be seen intuitively by consumers. For example, the material of a certain star is plastic. It refers to the material of the panel, and the quality of the panel material and processing technology directly determines the two important indicators of the panel’s firmness and durability, and it is the most important manifestation of the appearance.
The materials currently used on panels mainly include the following: iron, stainless steel, copper, aluminum alloy, zinc alloy, plastic, glass, etc. Generally, plastic and glass are rarely used as the main material.
