Description

Due to the global trend toward smaller and thinner electronic components, demand for phosphor bronze with higher strength and bendability has been increasing as the base material. To meet such needs, Harada has added a newly developed material to its products line-up, a high quality phosphor bronze (HQ).

This grade can be hot-dip tin plated.
