Teflon wire manufacturers tell you PTFE can not be tinned

Do you also think that (Teflon) PTFE wires can be tinned? But what I want to tell you today is: PTFE can not be tinned. Because the high temperature resistance of tinned copper is poor, and the manufacturing PTFE production workshop environment temperature is high, tinned copper meets high temperature within half an hour conductor will be oxidized black, chemical properties and the use of the period of time will deteriorate, the high temperature resistance of the manufactured PTFE can not reach the high temperature resistance standard, so PTFE can not be plated with tin.

You may say: I have bought tinned PTFE? Now there is no one on the market can do tin-plated PTFE, a few years ago there is a wire manufacturer in the United States can do PTFE tin-plated, but since last year did not do. You can buy tin-plated PTFE on the market, those are sellers with PFA or PVC and other materials to fake alternative PTFE, which can be tinned.PTFE can not be tin-plated in addition to nickel-plated and silver-plated options. Advantages of silver plating: silver-plated wire with good electrical conductivity, and its bright and glossy surface, and the silver layer has a high resistance to corrosion. Because of its surface layer of silver plating leads to its current density is greater than the current density inside the conductor, which is equivalent to reduce the cross-sectional area of the conductor, greatly enhancing the resistance of the conductor. Therefore, if the conductor surface layer of silver plating can reduce the surface resistance, which in general improves the conductor's ability to conduct electricity. Disadvantages: Silver-plated wire has no disadvantages except that it is more expensive than the other two coatings. Advantages of nickel plating: nickel plating process throughout the process has a very good environmental protection, does not produce harmful substances to human health and the environment. Chemical nickel plating layer combination of strong, white slippery good, small coefficient of friction, but also has a good brazing, can be welded, has a good corrosion. Disadvantages: The tensile strength of the wire will be reduced after the nickel-plated copper undergoes high heat treatment process. And nickel-plated copper on the tin is very difficult, if you want to tin, its technology has a high standard, otherwise it is difficult to get a good tin.
