172 Product Guide

Applications | Specifications | Mechanical and Chemical Data | Tolerances

Overview

Beryllium Copper 172 offers excellent corrosion resistance, good electrical/thermal conductivity, with a strength and hardness comparable to steels. Though harder than most other copper alloys, 172 is also less electrically conductive. Soldering and brazing are rated as good, but oxyacetylene welding is not recommended. Arc welding and spot welding are rated as good, seam welding and butt welding as fair. 172 can also be hot and cold worked. It is typically used for electrical components, fasteners, industrial pumps, bearings, firing pins, and other tools.
