Follow along as we show just how important it is.
Tin plated copper wire resistance.
If the bare wire has a matte finish the tin plating deposit will have more of a matte luster.
Copper plated areas of mild steel act as a mask if case hardening of such areas are not desired.
Also tin has relatively low conductivity and when plated over copper forms an inter metallic layer which will increase resistance compared to bare or silver plated wire.
The advantages of using tin plated copper conductors is the low cost increased solderability and corrosion resistance.
Tin plated steel is chromium plated to prevent dulling of the surface due to oxidation of tin.
Sounds simple but there s more to it than that.
What is tinned copper.
Mws offers tin plated wire in both bright die burnished and matte electrodeposits the appearance of tin plating is very much a function of that of the bare wire.
The tin coating provides a higher level of corrosion resistance and makes it easier to solder than mirror like multipurpose 110 copper wire.
Electroplating of acid gold on underlying copper or nickel plated circuits reduces contact resistance as well as surface hardness.
However tin plated conductor does have drawbacks.
Well the short answer is that tinned copper is copper coated by a base alloy such as solder better known as tin.
Tin has a relatively low melting temperature and therefore provides little if any improvement to the operating temperature range of copper.
Tinned copper vs bare copper the advantages of tinned copper are impossible to deny.
If the bare wire has a bright finish the tin plating will have a more lustrous appearance.
