1. Zinc alloy: Zinc alloy locks are produced in one molding process, with fast production speed and better quality than metal locks. Zinc alloy has good hardness and is easy to die cast into different types of metal locks without deformation. It is also easy to detect quality problems and improve them in a timely manner. After zinc alloy die-casting, excess raw materials can be recycled. The electroplating effect of zinc alloy is better than that of metal locks, and the treated surface is also the same. Zinc alloy electroplating is not easy to rust, and it is not easy to develop spots after sealing with oil.
2. Stainless steel: Stainless steel door locks are made of stainless steel, which is easy to integrate with doors and windows, healthier, and more environmentally friendly. Simple appearance and better practicality. The properties of stainless steel determine its fire resistance, high temperature resistance, and heat resistance. Stainless steel door locks are not easily damaged. Due to the stainless steel door lock being made of stainless steel, it has high density and can effectively prevent moisture. Easy to clean and maintain. Stainless steel door locks will not change color, and locks made of stainless steel will be new. Stainless steel door locks have a longer service life than other materials, and they are environmentally friendly and more in line with modern humanism.
3. Pure copper: The lock core of pure copper door locks is wear-resistant, and compared with other materials, the lock core has much better performance. Aluminum lock core is a representative of low cost, not wear-resistant and not fireproof. Copper lock cores have wear resistance and are easy to process. Compared to iron, it is soft and easy to open.
4. Space aluminum: Space aluminum door locks are lightweight, strong, uncoated, resistant to rust, aging, and have a long lifespan. Durable, environmentally friendly, high safety factor, diverse opening methods, and not easily deformed. Simple processing, easy operation, moderate price, and lightweight transportation. It is one of the most cost-effective choices for doors and windows. If the surface is to be coated, it is easy to anodize. Resistant to various environments, not afraid of moisture, and can be used in harsh environments.
