Advantages of BK Brass Door Cylinder Lock with Brass Knob from Jiangsu Elite Lock Co., Ltd. in corrosion resistance

1. Importance of corrosion resistance
In modern buildings, homes and security systems, door locks are not only a barrier to safety, but also need to have long-lasting durability and stability. Especially in harsh external environments, such as high humidity, salt spray, acid rain and other corrosive substances, the corrosion resistance of door locks is particularly important. If the surface or internal parts of the door lock are corroded, it will not only reduce its service life, but also may lead to a decrease in safety performance. In order to meet these challenges, Jiangsu Elite Lock Co., Ltd.'s BK copper mortise door lock uses high-quality materials and advanced production processes to ensure its excellent corrosion resistance in various environments.

2. Excellent corrosion resistance of copper
One of the biggest features of BK Brass Door Cylinder Lock is the use of high-quality copper. As a metal, copper has very strong corrosion resistance, especially when facing moisture, salt and other chemicals in the atmosphere, copper can form a natural oxide layer, which protects the copper itself and avoids further corrosion. Compared with other metals such as iron and steel, copper has more outstanding oxidation resistance and corrosion resistance, especially when exposed to humid environments for a long time.

The corrosion resistance of copper is particularly suitable for marine climates, coastal areas and other humid and salty environments. In contrast, materials such as steel are susceptible to corrosion and rust, especially in environments with high humidity. Copper is not only corrosion-resistant, but also resistant to erosion by many acidic or alkaline substances. Therefore, the service life of BK copper mortise door locks in various extreme environments is much higher than that of ordinary metal locks.

3. Advantages of surface treatment technology
In addition to selecting high-quality copper materials, Jiangsu Elite Lock Co., Ltd. also strives for excellence in the surface treatment of BK copper mortise door locks. In order to further improve the corrosion resistance of the lock, the surface of the BK copper mortise door lock adopts a precise electroplating treatment process to ensure a smooth surface and strong anti-corrosion performance. This electroplating process not only enhances the wear resistance of the copper material, but also effectively prevents the salt, acid and alkali substances in the external environment from corroding the surface of the lock body, thereby improving the stability and reliability of the lock in various harsh environments.

For door locks that are often exposed to the outdoors, the surface treatment process is one of the key factors that determine their corrosion resistance. Whether it is urban pollution, humid weather, or salt erosion in the sea breeze, BK copper mortise door locks can ensure that the locks work stably for a long time without being affected by their high-quality surface treatment technology.

4. Comparison with other types of locks
In the market, different types of lock materials and surface treatment methods vary greatly. For example, common steel locks are strong but susceptible to oxidation and rust, especially in humid environments. Although aluminum alloy locks have a certain corrosion resistance, the oxidation resistance of aluminum is relatively weak, and corrosion may still occur after long-term exposure to high humidity environments. In contrast, copper not only has excellent corrosion resistance, but also maintains long-term stability and is not easily affected by the external environment.

During the corrosion process, many aluminum alloy and steel locks may have problems such as spots and discoloration on the surface, and even material damage may occur under extreme conditions. The copper surface oxide layer of the BK copper mortise door lock can not only effectively prevent corrosion, but also keep the appearance of the lock beautiful and neat. Whether in the humidity of inland areas or in the salt spray of coastal areas, BK copper locks can show excellent corrosion resistance.

5. Practical application cases
BK copper mortise door locks are widely used in many fields that require high corrosion resistance locks, such as residential, hotel, commercial buildings and other places exposed to harsh environments in coastal areas. Taking coastal areas as an example, salt in sea breeze is a common threat to copper corrosion. However, with its strong resistance to salt corrosion, BK copper mortise door locks can continue to work in these environments without being affected, ensuring the safety and reliability of the door locks.

In some high humidity environments, such as mountainous areas and tropical climate areas, BK copper mortise door locks also show good corrosion resistance. Many customers said that the door locks using BK copper locks have never been corroded, rusted or damaged in appearance during long-term use.
