Home Products High Performance 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. EtchMet™ Alloy – Ultra-high strength and high stiffness alloy made for voice coil motor springs or optical image stabilization systems for consumer electronics. It has uniform microstructure, making it a great fit for photochemical etching. BrushForm® 158 Strip – 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 Alloy – Rod and wire with good resistance to stress relaxation and corrosion. VIEW A BRIEF VIDEO ABOUT FATIGUE STRENGTH The demands for materials that can meet higher performance requirements for burn-in and test socket (BiTS) applications continue to grow. Watch this video to learn more about fatigue strength and the alloys that best meet these needs. For additional information, see our High Temperature Electrical Connectors Application Sheet, highlighting our copper alloy attributes as they relate to BiTS. CUSTOMIZED HIGH STRENGTH ALLOY SOLUTIONS Alloy properties determine which material is best for each high strength application. We can help you select the best alloy for your application or provide unique alloy solutions metallurgically tailored to meet specific strength and performance requirements.
