Brass and copper can be identified by the naked eye, the texture of brass is harder, copper is the same as SoftBank and silver alloy, sterling silver is softer, and gold and silver will be hard a lot, but the color is not easy to distinguish.

In general, the igniting situation of the circuit contact will be silver plated, the inside is copper, the outside is plated with a thin layer of silver, the reason is that silver through the contact igniting, will generate an oxide layer like other metals, and silver oxide is better than pure silver conductive properties, so the general contact can not avoid igniting, the use of silver contacts, or silver alloy contacts.

How to distinguish silver contacts from copper contacts? Because there are too many factories making silver contacts, it is difficult to guarantee that some illegal businessmen use cheap copper contacts to replace silver contacts in order to seek more interests, and the general layman does not know where the difference between silver contacts and copper contacts is when buying.

Copper and brass can be identified by the naked eye. In addition, copper is soft, and the texture of brass is hard, silver alloy and silver are the same situation, gold and silver will be a lot harder and sterling silver is softer, but it is not particularly distinguishable in color. In addition, there is a general ignition situation of the circuit contacts will use silver contacts, and the inside is copper, the outside is plated with a thin layer of silver, the reason for doing so is that silver through the contact igniting, will generate an oxide layer like other metals, and silver oxide is better than pure silver conductive properties, so the general contact can not avoid igniting, the use of silver contacts or silver alloy contacts.

Silver contact product adopts thick power cord and international standard product size, through repeated trials and tests, taking into account safety and beauty at the same time, the reasonable size of the product makes the heat dissipation faster and extends the service life of the strip. The innovative plug is ergonomically designed and the silver contact makes the product easier to use. At the same time, the product adds lightning protection function, silver contact electricity is safer, built-in electromagnetic anti-interference filter, play a power purification function, protect electrical equipment. The silver contacts designed and produced by our company have the characteristics of high dimensional precision, high bonding strength, easy to control contact hardness and good electrical conductivity.
