Below is a list of Wire Connectors manufacturers from Roanoke, Virginia. Wire connectors are used to connect one or more conductive wires to various electrical circuits. The most common material used to manufacture conductive metal wire is copper, due to its extremely high electrical conductivity. Another highly conductive metal is silver; however, the high cost of silver makes it a much less popular choice for industrial applications. Some common metal alloys used to manufacture conductive metal wire include nickel-titanium and niobium-titanium; however, neither of these alloys can meet the overwhelming popularity of copper wire.
