Brass Key
The copper key is a type of key made from copper, typically used to open locks with copper or copper alloy cores. Copper keys have certain advantages over keys made from other materials, such as good toughness and resistance to breakage, as well as high corrosion resistance and wear resistance. With the development of technology, many modern locks have adopted more advanced unlocking methods, such as electronic locks or smart locks, and copper keys are mainly used for traditional lock core types, such as copper locks, orange locks, and so on.
