Home Products Alloys Spring and Connector Alloys High Strength Alloys HIGH STRENGTH ALLOYS FOR ELECTRONIC SPRINGS & CONNECTORS When strength 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-strength alloys are optimized for signal connector applications. Alloy 360 – Nickel-based strip with excellent formability and outstanding resistance to stress relaxation and corrosion. The highest strength alloy available in this class. Alloy 25 – Heat-treatable copper alloy strip, rod and wire with excellent formability and good conductivity. Offers the highest strength available in a copper alloy. Alloy M25 – Heat-treatable copper alloy rod that is easy to screw machine. Good conductivity with the highest strength available in a copper alloy. BrushForm 158 – Strip with optimal formability and good resistance to stress relaxation and corrosion. Alloy 190 – High-strength strip that does not require heat treatment. Outstanding shape control and good resistance to stress relaxation. Alloy 290 – High-strength strip that does not require heat treatment. Good formability and stress relaxation resistance. ToughMet 3 – Rod and wire with good resistance to stress relaxation and corrosion. BrushForm 96 – Strip with good strength and formability.
