Phosphor bronze

Description

A hard, corrosion-resistant, bronze alloy. Phosphor bronze was first produced in Vienna about 1870. It contains copper (80-95%), tin (1-10%), small amounts of phosphorus (0.03-0.5%). It may also contain antimony (9-12%) for hardness or lead (10%) for ductility. The phosphorus acts as a deoxidizing agent and makes the bronze very corrosion resistant. Phosphor bronze is used in machine parts, electrical switches, springs, and tubing. It is the preferred bronze for use in marine environments.
