Hyper Phosphor Bronze

C5210 (HP)

C5210 (HP)
High Strength Phosphor Bronze for Springs

Overview

Hi-Performance C5210 alloy, (C5210 (HP)), was developed by enhancing the conventional phosphor bronze alloy C5210. Having the same chemical composition as C5210 but with higher strength and excellent bend formability, it exceeds ordinary phosphor bronze in meeting customer requirements as a material in switches, connectors, relays, and other electronic parts.
(We provide the Hi-Performance Series-materials with the same composition as conventional products but with advanced material properties achieved by precision process control.)
