The difference between iron padlock and copper padlock?


1. Material characteristics
Copper lock: Copper has natural corrosion resistance, can resist environmental factors such as humidity and oxidation, and has a longer service life. Copper has better ductility and is easy to process into complex shapes.
Iron lock: Iron is prone to rust and corrosion, especially in humid environments, and its durability is poor.
2. Aesthetics and texture
Copper lock: With a unique surface gloss, it will develop a classical aesthetic over time. The texture of copper locks is thicker and feels better.
Iron lock: The appearance is relatively ordinary, lacking the decorative qualities of copper locks.
3. Security
Copper lock: Due to its high hardness, copper has stronger resistance to damage and prying.
Iron lock: The strength is still acceptable, but long-term use may affect safety due to corrosion.
5. Applicable scenarios
Copper lock: suitable for occasions that require long-term durability, high safety, or decorative needs.
Iron lock: commonly used in temporary or low-cost scenarios, but rust prevention and maintenance should be taken into account.
