Disclosed is a cleaning agent for copper wiring which is excellent in an effect of inhibiting corrosion of copper wiring (copper corrosion inhibiting effect), while having no affect on the contact resistance.

How to Determine Wire Sizes for Stranded Copper Wire

This solder-plated copper wire affords good cohesion of the lead-free solder plating layer and the copper wire, and exhibits low yield strength.

The process is particularly suitable for making copper wire, especially copper wire having a very thin diameter (e.g., about 0.0002 to about 0.02 inch).

The backing layer (42) has parallel lines of copper wire which are arranged transversely to the parallel lines of copper yarn in the ground structure (14) to form a grid.

The present invention adopts a three-dimensional porous current collector material, such as a copper foil mesh, a copper wire mesh, foamed copper, or foamed nickel.

The ground structure (14) comprises a copper yarn arranged in parallel lines.

A wire harness (1) is provided with a copper wire (3), an aluminum wire (4), and a ground terminal (2) to which the copper and aluminum wires are connected.

Then, one of the insulating wires (6) is removed to form a copper wire (9) in the vacant portion by copper vacuum deposition.

The first and second paper-covered copper wires (5A, 5B) comprise copper wire and insulating paper wrapped therearound.

Described is a device and method for manufacturing stranded copper wire, the stranded wire being wound on a reel (10) using a traverser (20).

This undeniably would require a lot of copper wire.

Well compared to conventional metal wire (copper wire), optical fibers are:

Thus, the copper has superior resistance against oxidation reaction or other unnecessary reactions, thereby improving the performance of the copper wire or the copper electrode.
