The actual purpose of the copper coating is corrosion resistance. Copper, gold as well as silver, and mercury have superior resistance to corrosion, although ready other metals (never found totally free inside nature) such as metal, aluminum as well as magnesium are often corroded. Reputable other metals for example copper end up being the cathode anytime joined up with in addition to a smaller amount of reputable other metals inside the living from the electrolyte (water). Much Less noble metals get to be the sacrificial anode as well as rust aside.

The threads are to be created with a cold rolling process which ensures strength and maintains the molecularly bonded copper covering along the full length of the threads. Cold-rolled threads are usually efficient in comparison with cut- threads. The standard copper thickness is 0.25 mm. greater copper thicknesses are also available.
