What is the smart lock all stainless steel and semi-steel lock body?

In many people's impressions, most of the locks of smart locks are similar, no matter the appearance or the size, so it is difficult for ordinary consumers to distinguish the quality between different locks. However, consumers are concerned about the difference between a smart lock of one thousand two thousand yuan, two thousand three thousand yuan and a smart lock of several hundred dollars.

Before answering this question, you can take a look at the following pictures. Do you think the two locks on the left and right, which quality is good, which one is of poor quality? For professionals, one can see that the left side is all stainless steel lock body, the right side is a semi-steel lock body, so the left lock body is better than the right lock body.

So what is an all stainless steel lock? What is a semi-steel lock body? What is the difference between the two? Why do well-known brands and quality-conscious companies use all-stainless steel locks? And the cheap hundreds of smart locks are mostly semi-steel locks?

Let us first look at the all-stainless steel lock body. From the literal point of view, the so-called all-stainless steel lock body is the lock body shell, the lock tongue, the guide piece, the heaven and earth hook hook and the inside of the lock body are all made of 304 stainless steel. As we all know, stainless steel has good heat resistance, corrosion resistance and oxidation resistance. It is used to produce lock body, which is durable, safe and stable, but costly and expensive. Therefore, only the quality of smart lock brands and enterprises use all stainless steel locks.

The so-called semi-steel lock body is that except for the guide piece, the main lock tongue, the anti-lock lock tongue and other parts are made of stainless steel, the oblique tongue is made of copper, and the lock body is mostly iron, so the cost of the semi-steel lock body is low. The price is cheap, and most of them are used in cheap smart locks of several hundred yuan or five or six hundred yuan.

It is not difficult for users to distinguish all stainless steel and semi-steel locks. One is that from the appearance and appearance color, the all-stainless steel lock body is brighter and has a texture, while the semi-steel lock body shell is whitish, the color is dull and has no texture; the other is distinguished from the weight, and the all-stainless steel lock body is obviously heavier than half. Steel lock body.

Of course, the intuitive is to divide the price. In the research of Yongkang in July this year, I learned that the purchase price of semi-steel locks is between 10-30 yuan, and the purchase price of all-lock locks is more than 30 yuan. Most of the locks used by big brand locks are mostly 80 yuan or more, or 80 yuan or more. At the retail price, the double-fast double-lived all-stainless steel locks are mostly above 100 yuan, while the semi-steel double-fast double live locks are mostly between 50-100 yuan.

Only through a simple lock comparison, we can clearly understand that one or two thousand, two or three thousand smart locks, the reason is only in the lock body is better than two or three hundred yuan cheap smart lock A lot, the cost can not be compared. Therefore, expensive things have its own truth, this is a penny.

Especially to buy smart locks, don't buy cheap irons for the sake of saving seven or eight hundred dollars. This is a smart lock that is purchased for convenience and you can't return home.
