Contact springs - Import export

Phosphor Bronze A is a Copper base spring material with a good combination of strength, formability, and corrosion resistance. The material is suitable for use in certain contact springs and diaphragms. The alloy has good formability up to moderate strength. It can be soldered, silver brazed, and resistance welded. Available Sizes: Phosphor Bronze A is available from Hamilton Precision Metals as strip products in thicknesses from 0.001” to 0.020” (0.0254 mm to 0.508 mm) in widths up to 12.0” (304.8 mm). The material conforms to ASTM B 103 and UNS C51000.

MP35N®-LTi is a nonmagnetic nickel-cobalt-chromiummolybdenum alloy that has excellent corrosion resistance, can obtain ultrahigh tensile strengths (300 ksi) through work hardening and aging, and has good toughness and ductility. Applications include electrical components, spring contacts, medical instruments, such as stents and implant electronic connectors, chemical, food processing and marine environments. After work hardening, MP35N® alloy can be aged in the temperature range of 800/1200°F for increased strength. MP35N® will only respond to aging if in the work hardened condition. Service temperatures up to 750°F are recommended for work hardened material. MP35N® can be successfully TIG welded. MP35N® is produced by double vacuum melting, and as such, has a low nonmetallic inclusion level. Available Sizes: MP35N®-LTi is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.030” (0.0127 mm to 0.762 mm) and widths
