My company's long-term production supply various phosphorus copper contact piece. Brass contact piece, beryllium copper. Stainless steel. Manganese steel contact piece, material thickness 0.08 to 10 mm, specification variety, complete kinds, including remote control aircraft. Clocks. My company has the mold, the toys, and other contact pieces and a small amount of inventory, all parts conform to the requirements of the ROHS, and can through 12 hours salt spray test, welcome to inquire!

Contact piece of knowledge:

1 what is the battery contact piece of material, electronic product?

One is brass plating, is a kind of nickel

2, battery connector what material is the best?

The best copper nickel plated nickel take, nickel-plated steel strip in the end, by the same token, on the contrary, the price generally underground factories and large battery combination of nickel plated steel strip with more and more mobile phone batteries more than normal with nickel belt, copper nickel plating is less used

3, do contact pieces in the power supply plug is what's it made of?

The ac adapter disconnected, batteries, only watch, the fear of the computer lights ablaze, prove the contact is good, try to borrow a battery. Battery life is 500 times, discharge cycle, with 3, 4 years is not line, if you often use batteries or improper use, shorter service life. Computer bad internal charging circuit is unlikely. 220 v power socket with a good quality, poor contact will cause repeated charge and discharge.

4 why three contact piece, mobile phone battery? What role respectively?

The positive and negative function, the function of contact each model is different, with testing temperature, test voltage, battery model test, and is responsible for the vibration and so on

5, the inside of the switch contact with copper do?

Actually not copper in particular, but copper above the protrusions contact special, we can see sparks when closing, so the demand for contact is higher; Many are sterling silver, silver alloy or expensive materials such as platinum, generally choose the high electrical conductivity, heat resistance, oxidation resistance (chemical performance is stable).

6, the power contact is generally with what brand of copper?

Phosphor bronze c5191
