Applications | Specifications | Mechanical and Chemical Data
Overview
Beryllium Copper 173 offers excellent corrosion resistance, workability, and formability. It is also easy to machine. 173 is especially useful in environments that require high strength, fatigue resistance, wear resistance, and electrical conductivity. It is typically used in contact bridges, electrical switches, electric motor components, other electronic components, washers, screws, bolts, other fasteners, shafts, pump parts, valves, non-sparking safety tools, springs, bellows, welding equipment, tubing, and firing pins.
