Sumitomo Electric's electroplated wires are
used for various electronic parts in the automotive,
electric and electronic industries.

Enabled by own production technologies,
the wires have uniform electroplating thickness and
smoothness even on the flat wire surfaces.

Reflow-tin-plated wires have used in
various types of connectors for automotive parts
since the first stage of lead-free implementation.
Our products have been highly acclaimed for
long-standing adoption in the market.

Wire Drawing Technology

Wire drawing of processing-resistant materials such as copper alloy wire

Sumitomo Electric can manufacture not only "round" wire but also "rectangular" and "flat" wire with high oblateness.

Unique Production Facilities

Sumitomo Electric has striven for more than thirty years to meet our customers' needs for all sorts of round and rectangular wires.

Electroplating Technology

Tin / Nickel* / Silver**

For weather resistance and connectivity,
electroplating on copper, brass,
phosphor bronze and copper alloy wires are available.
*Manufactured by Sumitomo Electric Group Companies
**Under development

Electroplating on Hoops

Metal materials and wires wound on hoops (reels) are
plated at high-speed by "reel-to-reel" and "continuous" method.

Development

Sumitomo Electric are developing electroplating on
aluminum wire that attracts attention as light-weight conductor.

High Quality

Superior electroplating uniformity as well as High Dimensional Precision

Smoothness of the flat surface and high dimensional precision are ensured by smooth finish after electroplating.

For Automotive, Electric and Electronic Parts Application

Sumitomo Electric strives to have accurate understanding of the reliability required for automotive,
electric and electronic parts to reflect over engineering development and product design.
