The advantages and disadvantages of locks of different materials
2020年07月20日

The material of the lock generally includes zinc alloy, stainless steel, pure copper, aluminum, etc. Locks of different materials have different advantages and disadvantages.

Zinc alloy locks:

  • 1. Zinc alloy locks are produced once, and the production speed is fast.
  • 2. The quality of zinc alloy lock is better than metal lock. Zinc alloy has good hardness, is easy to die-cast into different types of metal locks, will not deform, and it is easy to find quality problems and improve quality problems in time. Tin lock does not have this feature.
  • 3. After die casting of zinc alloy, excess raw materials can be recovered.
  • 4. The zinc alloy locking electroplating effect is better than the metal lock, and the treated surface is also the same. Zinc alloy electroplating has foaming and pitting corrosion, which is relatively small compared to iron plates, and the surface is relatively smooth and smooth.
  • 5. Zinc alloy plating is not easy to rust, and it is not easy to grow spots after sealing the oil.

Stainless steel locks:

  • 1. Stainless steel door lock is made of stainless steel, which is easy to combine with doors and windows. Stainless steel door locks are healthier and more environmentally friendly. The appearance is simple and the practicability is better.
  • 2. The nature of stainless steel determines its fire resistance, high-temperature resistance and heat resistance, the stainless steel door lock is not easy to damage;
  • 3. Because the stainless steel door lock is made of stainless steel, the density is high and it can effectively prevent moisture;
  • 4. Easy to clean and maintain.
  • 5. Stainless steel door lock will not change color, the lock made of stainless steel will be new.
  • 6. Stainless steel door locks have a longer service life than other materials. Stainless steel locks are environmentally friendly and more in line with modern humanism.

Pure copper locks:

  • 1. Copper material is wear-resistant. Compared with other materials, the lock core is much better in terms of performance. Aluminum lock core is a representative of low cost, not wear-resistant and fire-proof.
  • 2. The iron lock core is fireproof, not abrasion resistant, not easy to process, but has good fire resistance. The copper lock core is wear-resistant and easy to process. It is not fireproof. Compared with iron, it is soft and easy to open. Iron security is not enough.

Aluminum locks:

  • 1. Light weight, high strength, no coating, not easy to rust, aging, long life.
  • 2. Durable, environmentally friendly, high safety factor, various opening methods, not easy to deform.
  • 3. Simple processing, simple operation, moderate price and light transportation.
  • 4. It is one of the most cost-effective door and window options.
  • 5. If the surface is to be coated, it is easy to anodize. It can withstand various environments and is not afraid of humidity. It can be used in harsh environments.
