Like friends watching science fiction movies, envy when they see those cool high-tech doors in the movie, voice-activated, brushing, brushing pupils, and even open the door by examining DNA, strange , Varied.
And with the advances in technology, many of the smart locks we see in the movies, and now we can also use at home, but many people at the time of the purchase focus only on the smart lock smart features, and its security and practicality However, there is not a lot of attention, but in the final analysis, the smart lock is still an important part of our efforts to prevent outsiders from entering the home. Therefore, in addition to its diverse and intelligent functions, workmanship and materials are also very important.
For any one product, in addition to the function, appearance, performance, the value is not negligible part of the value of the decision.Which smart lock, the use of which material not only affects the price, the safety of the lock is also very important , Although there is no 100% can not be destroyed material, but compared with the plastic shell, the safety of the metal material is bound to be higher.
In the smart lock, different locations will use different materials, so each lock will be composed of many materials, which need to focus on the lock body and the outer panel material.
Lock body material
At present, most of the material of the smart lock body is made of copper + stainless steel, and the stainless steel is used in other parts of the lock bolt, the transmission structure, the copper shell, etc., which is the most cost-effective match.
The reason why copper is used as a material is that copper has strong abrasion resistance, high strength, high hardness and corrosion resistance, and the plasticity of copper is strong enough to make a very finely-structured cylinder, Security, but the price of copper is more expensive, so the entire lock body with copper, then the cost will be very high, resulting in the price of the entire smart lock.
The hardness of stainless steel though higher than copper, but its poor plasticity, processing difficult, it is difficult to make a fine cylinder structure, it is usually only used for the external structure of the lock body, which can reduce the entire lock body cost.
Outer panel material
Compared to the lock body material, smart lock outer panel material to be more optional, it is also more subject to everyone's attention, the discussion for the panel material will be more. And the same lock, the outer panel is also a lot of A part of the composition, the various parts of the material used are also different, including: stainless steel, copper, aluminum alloy, zinc alloy, glass, plastic and so on.
So what are their advantages and disadvantages?
1, stainless steel: high hardness, durable, difficult to shape, the price is medium
Stainless steel is usually referred to here is 304 stainless steel, this material high hardness, to some extent, to prevent the smart lock is violent damage, but stainless steel processing is too difficult, so the appearance of stainless steel locks are generally simple style .
Price, stainless steel in all common smart lock material is medium, high-priced smart lock to use more.
2, aluminum alloy: easy to shape, light weight, low hardness, the price is uncertain
Aluminum is characterized by easy molding, easy processing, weight is lighter, although the hardness is not particularly high but not low, but affordable, but for many consumers, aluminum alloy door locks are very low, so with aluminum Alloy smart locks do not have many businesses.
Aluminum prices are high-end low-end have, but in order to reduce costs, most of the smart locks are used in low-end aluminum alloy.
3, copper: high hardness, easy molding, complex process, the cost is slightly higher
There are many types of copper, the general smart lock is usually used brass. Brass high hardness, durability, surface treatment is easy, as a smart lock panel is more appropriate material.But the process is a bit complicated, so it is not All manufacturers have the ability to process.
Although the price of copper may be slightly higher, but also acceptable, the current market with smart panels made of copper lock is small.
4, zinc alloy: many advantages, the current mainstream material
Zinc alloy is currently used in the most intelligent type of material lock, with easy processing, easy molding characteristics, while the hardness and strength are also in line with public demand for locks, the current smart lock material on the market most of the use of zinc alloy, technology Already quite mature, very practical.
However, the price of zinc alloy is high and low, which depends on the overall price of the lock.
5, plastic: aided mainly
Some people may ask, plastic so fragile, can also be used in the smart lock it? Yes, there are indeed some brands of smart lock the outer panel made of plastic large area, especially some Korean brands. The biggest advantage of plastic is low price , Easy to handle, come up with what shape can be done.The disadvantage is too easy to be destroyed.Currently made smart locks, not all plastic, except for those who sell hundreds of dollars, can not wait even the brand of low-priced products .
6, glass: pure auxiliary
Glass material in the smart lock is pure auxiliary materials, mainly used in the password keyboard, I believe I will not dare to make a smart glass lock it, no one will buy. Glass for the password keyboard Also need special coating treatment, to ensure that the password on the keyboard is not easy to leave fingerprint marks, so as to avoid password cracking.
So that stainless steel is more suitable as a smart lock so far, under the conditions of adequate budget, try to choose the smart lock stainless steel.
For us, security should always be the top priority, if you just want to experience the smart lock to bring the sense of technology, without considering the safety of home, if the accident, later regrettable .Of course, if you are at home, and If it is not used as a gateway, it is another matter, but in this case, what is the point.
