Buying smart locks is not more important than smart

In the final analysis, smart locks are still a key to preventing outsiders from entering the home. For any product, apart from its function, appearance and performance, the material is also a part that cannot be ignored.

Friends who like to watch science fiction movies are envious when they see the cool high-tech doors in the movie. Voice-activated, fingerprint-fingered, brushed pupils, and even open the door by testing DNA, all sorts of weirdness, all sorts of things.

With the advancement of technology, many of the smart locks we can see in movies can now be used at home. However, many people only pay attention to the intelligent functions of smart locks at the time of purchase. However, there are not many concerns about their security and practicality. We must know that smart locks are still a lock in the final analysis, which is an important part of preventing outsiders from entering the home. Therefore, in addition to its diversified intelligent functions, workmanship and materials are also very important.

For any product, apart from its function, appearance and performance, the material is also a part that cannot be ignored. For smart locks, which kind of material is used not only affects the price, but also the safety of the door lock. Although there is no 100% material that cannot be destroyed, the safety of the metal material must be higher than that of the plastic housing.

In the smart lock, different materials are used in different positions, so each lock will be composed of many materials, among which the lock body and the outer panel material need to be focused on.

Lock body material

At present, the material of the smart lock body is mostly composed of copper and stainless steel. The tongue, the copper of the transmission structure, and the stainless steel of the housing are the most cost-effective components.

The reason why copper is used as a material is that copper has strong wear resistance, high strength, high hardness, corrosion resistance, and strong plasticity of copper. It can make a very fine structure of the lock core and enhance the lock core. Security, but the price of copper is expensive, so if the entire lock body is made of copper, the cost will be very high, resulting in a long price for the entire smart lock.

Although the hardness of stainless steel is higher than that of copper, its plasticity is poor, and it is difficult to process. It is difficult to make a fine lock core structure, so it is usually used only for the external structure of the lock body, which can reduce the overall lock body. cost.

External panel material

Compared with the lock body material, the material of the outer panel of the smart lock is more optional, and therefore it is more concerned by everyone, and the discussion of the panel material will also be more. Like the lock body, the outer panel is also composed of many parts. The materials used in each part are also different. They mainly include: stainless steel, copper, aluminum alloy, zinc alloy, glass, plastic and so on.

What are their advantages and disadvantages?

1. Stainless steel: high hardness, durable, difficult to mold, medium price

The stainless steel mentioned here usually refers to 304 stainless steel. This material has a high hardness and can prevent the smart lock from being violently destroyed to some extent. However, stainless steel is too difficult to process, so the appearance of stainless steel locks are generally simple style.

In terms of price, stainless steel is medium in all common smart lock materials, and high-priced smart locks are used more often.

2. Aluminum alloy: easy to shape, light weight, low hardness, indefinite price

The characteristics of aluminum alloys are easy to form, easy to process, lighter in weight, and the hardness is not particularly high but not low, and the price is moderate. However, for many consumers, aluminum alloy door locks are very low, so there are not many merchants that use aluminum alloy for smart locks.

The prices of aluminum alloys are high-end and low-end, but in order to reduce costs, most smart locks use low-end aluminum alloys.

3. Copper: high hardness, easy molding, complicated process, slightly higher cost

There are many types of copper, and brass is commonly used in general smart locks. Brass has high hardness, good durability and easy surface treatment. It is a suitable material for smart lock panels. However, the process is a bit complicated, so not all manufacturers are capable of processing.

Although the price of copper may be slightly higher, it is also acceptable. At present, there are not many smart locks available on the market for copper panels.

4. Zinc alloy: many advantages, the current mainstream material

Zinc alloy is currently the most used type of smart lock material, with the characteristics of easy processing, easy molding, while the hardness and strength are also in line with the requirements of the public on the lock, most of the current market, the smart lock material using zinc alloy, process It is quite mature and practical.

However, the price of zinc alloy is also high or low, depending on the overall price of the lock.

5. Plastic: Auxiliary

Some people may ask, plastic is so fragile, can also be used in the smart lock? Yes, there are indeed some brands of smart lock outer panel made of plastic in large areas, especially some Korean brands. The biggest advantage of plastics is its low price, easy handling, and the ability to come up with what it is. The disadvantage is that it is too easy to be destroyed. At present, there are not many plastics used in domestic smart locks, except for those low-priced products that sell hundreds of bucks and can't even be branded.

6. Glass: Pure Assist

Glass material in the smart lock is purely auxiliary material, mainly used in the password on the keyboard, I believe it will not dare people to do a smart lock of pure glass, do it no one will buy. The glass used for the password keyboard is also required to be coated with a special coating. It is necessary to ensure that fingerprints are not easily left after the password is pressed on the keyboard so as to prevent the password from being cracked.

Therefore, stainless steel is the most suitable material for smart locks so far. Under the conditions of ample budget, choose the stainless steel smart lock as much as possible.

For us, security should always be the first priority. If you just want to experience the sense of technology brought by smart locks, regardless of home security, once things go wrong, you will regret it. Of course, if you use it at home, not as a gate, it's a different story, but what's the point? (Text / Wen Jiawei)
