Benefits of tinned wire. Tin is a useful plating for copper because it not only helps to boost copperâs properties, it also helps the wire to last much longer than it would normally. In fact, a 12 gauge tin coated copper wire can last up to ten times longer than a similar 12 gauge bare copper wire.opper has a great conductivity (second only to silver,) a durable tensile strength and is easy to machine into wire and other specialty wire and cables. For these reasons, copper finds itself being used to create many alloys that are used for electrical work or for machining such as brass, nickel, silver or bronze.
Types. THHN wires come in two basic formats -- stranded and solid core. As a stranded cable, THHN is available in sizes from 14 awg to 750 kcmiL, and as a solid cable in sizes 14 to 10 awg.It is generally manufactured in copper or aluminum.ave.
