Home Products High Performance Alloys Spring and Connector Alloys High Conductivity Alloys HIGH CONDUCTIVITY ALLOYS FOR ELECTRONIC SPRINGS & CONNECTORS When conductivity is the most important requirement for your electronic spring or connector application, choose from a range of highly engineered alloys designed to maximize reliability and service life. The following high-conductivity alloys are optimized for power transmission applications. Brush® 60 alloy – Strip with the best formability and strength combination. Outstanding resistance to stress relaxation. Alloy 174 – Strip, rod and wire alloy with high yield and fatigue strength and good resistance to stress relaxation. Works well at higher temperatures. Alloy 3 – Rod and wire with a good combination of strength and resistance to stress relaxation. Brush 1915® material – Cold headable rod that performs well at elevated temperatures and resists corrosion. High tensile and yield strength with good resistance to stress relaxation. Brush® 1916 material – Screw machinable rod with good performance at elevated temperatures. High tensile and yield strength with good corrosion resistance. Alloy 390® material – Strip with high fatigue strength and stress relaxation resistance at elevated temperatures. The highest strength in this class of materials. Alloy 390E – Strip with high strength and good formability.
