260 Brass Product Guide

Applications | Specifications | Mechanical and Chemical Data

Overview

The most ductile of the yellow brasses, 260 brass also has a good strength, finishing capabilities and corrosion resistance. It is also easily machined and cold formed. 260 brass should not be used in projects where it will come into contact with acetic acid, hydrochloric acid, nitric acid, or ammonia. Due to the high zinc contact, it shouldn't be soldered. Typically used in architecture, electrical parts, fasteners, and ammunition casings.
