Door locks are very common products, but many people know very little about the lock cylinders of door locks. Let me introduce you to the relevant knowledge of the lock cylinders.
Lock material:
1. Copper:
Advantages: Copper is one of the best pure metals. Brass is an alloy of copper and zinc, which has strong wear resistance, high strength, high hardness, and strong corrosion resistance. And the plasticity of copper is strong.
Disadvantages: Pure copper is an expensive metal, and the processing technology is complicated, so the price of pure copper products is usually higher.
2. 304 stainless steel:
Advantages: stainless steel material has good corrosion resistance and wear resistance.
Disadvantages: The manufacturing process is complicated.
3. Zinc alloy:
Advantages: simple processing technology, easy to shape, low price.
Disadvantages: Abrasion resistance is slightly worse.
4. Aluminum and iron:
The lock core performance, strength and wear resistance of these two materials are not as good as the above three.
