Pacing ElectrodeA nonmagnetic super alloy composed of nickel-cobalt-chromium-molybdenum, MP35N is prized for its ultra high tensile strength, ductility and excellent corrosion resistance. Additionally, MP35N is resistant to sulfidation, high temperature oxidation, hydrogen embrittlement and most mineral acids. In its fully work hardened condition, MP35N can withstand temperatures up to 750 degrees Fahrenheit (399 Celsius), making it an excellent choice for high temperature and high stress environments. Resistant to pitting, cracking and crevice corrosion makes MP35N a strong, durable choice for many types of fasteners, springs and nonmagnetic electrical components in the medical industry.

MP35N is also utilized in high performance medical hardware such as prosthetic and orthodontic devices and surgical guide wires. Dependable, durable and easy to fabricate, MP35N is an ideal choice for precision devices such as “alligator” surgical spring clips which are used to close veins and arteries during surgeries, and for prosthetic devices, which must bear body weight and torsional forces while being highly biocompatible and corrosion resistant. When used in prosthetics and orthodontics, MP35N’s superior biocompatibility helps ensure the patient’s natural defense mechanism, designed to reject foreign objects, will not be engaged.


Confluent Maine has drilled MP35N starting hollows which have subsequently been drawn down into pacemaker lead wires. The finished diameter of this wire – thinner than a human hair – necessitates superb concentricity in the starting hollows to ensure consistently high quality production yields. MP35N’s strength, corrosion resistance and versatility also make it a dependable choice for the oil and gas sector, aerospace and automotive industries. Confluent Maine’s experience machining MP35N makes us a valuable partner anywhere this versatile alloy needs to be employed, whether in the surgical arena, an aircraft engine or a nuclear reactor.
