HQ Phosphor Bronze with High Strength and Bending Workability

As electronic devices and parts become smaller and thinner, the need for high strength and precision in the phosphor bronze as the base material also increases.

To meet these needs, we have established a production system for High Quality phosphor bronze with high bending workability (HQ series) in addition to our existing lineup.


Physical Properties

The HQ series is a phosphor bronze with improved mechanical properties through controlling the machining process. It has the same alloy composition as regular phosphor bronze and its physical properties are maintained.
