Lead wire (CP wire/copper wire/aluminum wire), cable conductor

We offer a broad lineup products of the world's leading manufacturers , which is high-quality and used for a wide range of applications.

CP wire/copper wire

It is used as lead wires and conductors for electronic components which is on printed circuit boards. We offer high-quality, stable products.

CP wire/copper wire
Uniform plating thickness
We supply high-quality products by electroplating through our unique technologies. We can also develop products that meet your requirements.
In recent years, as environmental problems have become serious social issues, we have been providing products that are lead-free.
Electroplating and hot dipping are possible
Both electroplating and hot dipping can be supplied as standard products. It is also possible to develop products that meet customer needs.
