Powered by our world-class connector materials, we are expanding our business in the global market.
DOWA's metal processing business began from the manufacturing of wrought copper and copper alloy products made from copper and zinc as the main raw materials. Since then, we have expanded our business to high-performance copper alloy products with the development of automotive and electronic device markets
Copper alloys and nickel alloys
In addition to copper and yellow brass, we offer a large number of
high-performance copper alloys such as NB-109, which has become a standard material
for automobile connectors.
We are capable of supplying our alloys globally thanks to our
technology alliances with manufacturers around the world. Our products are widely
used in automobiles, mobile phones, personal computers, semiconductors, batteries,
and more.
Plating
We provide reflow tin plating of equal quality from our three bases in Japan, China,
and Thailand.
We also offer advanced reflow plating with superior heat
resistance and STAR plating that reduces the insertion force in connectors.
Fabricated products
Leveraging the material technology and analysis technology that we have developed from the material level, we also provide fabricated products such as electronic parts, hot forged parts, machined parts, and heat sink bases.
