485 Brass Product Guide


Applications | Specifications | Mechanical and Chemical Data | Tolerances


Overview

Like 464, this is known as "naval brass" because it is regularly used in marine environments. It has an extremely high corrosion resistance, good strength, and excellent resistance to zincification. However, there is better machinability due to higher lead content than 464. While good for hot forming work, 485 should not be cold worked. Additionally, 485 can be easily brazed or soldered, but welding is not advised. This alloy is typically used in marine hardwear, wear plates, bushings, fasteners, condenser tubes, and, true fact, cannons.
