At California Fine Wire, we can fulfill any wire requirement, no matter how small or unusual. This includes fine wire with niche superalloys. MP35N is a superalloy that’s ideal for a wide range of medical devices and healthcare technology. This page will cover its properties and medical applications to help you determine if MP35N is right for your needs.

What Is MP35N Alloy?

MP35N is a specialty nickel-cobalt superalloy that has an excellent degree of physical strength, durability, and corrosion resistance. These properties make MP35N a popular material option for various medical, surgical, and dental applications.

Manufacturers also prefer MP35N because it’s highly ductile and formable, making it an excellent choice for forming high-strength wire.


One of the key advantages of MP35N is its resistance to damage. It can resist the following types of damage:

  • Crevice corrosion
  • Stress corrosion cracking
  • Oxidation corrosion
  • Corrosion from chlorides


MP35N can be melted through Vacuum Induction Melting (VIM). Many manufacturers then remove impurities through Electro Slag Remelt (ESR) processes. A third stage, Vacuum Arc Remelting (VAR), further processes the alloy to make it easy to work with.

MP35N Wire Applications

Because this superalloy offers excellent strength, age hardening capabilities, and resistance to multiple forms of corrosion and physical damage, MP35N is an excellent choice for a wide variety of medical and healthcare applications. These include:

Medical/Surgical Implants

The strength, ductility, and corrosion resistance of MP35N wire make it an ideal material for medical and surgical implants. The ASTM F562-00 Standard Specification for Wrought Cobalt-35 Nickel-20 Chromium-10 Molybdenum Alloy for Surgical Implant Applications dictates the requirements for MP35N used in the manufacture of surgical implants. The alloy composition covered by this specification has been successfully used in human implants and ensures consistency when manufacturing medical devices. Specific examples of implants that use MP35N include knee joints, bone plates, heart pacer electrodes, and more.

Dental Equipment

MP35N offers biocompatibility, superior strength, and corrosion resistance. These properties make it an ideal material choice for dental brackets and wires used for braces. MP35N can also be used for various dental implants and other orthodontic devices.

Medical Wires

MP35N can be formed into braid and coil wire for use in precision medical devices such as catheters. MP35N wire can be used in a wide range of catheter products, including vascular catheters, EP catheters, micro-catheters, braided catheters and shafts, and coiled shafts. Other medical applications for MP35N wire include:

  • Cardiac rhythm management (CRM) devices
  • Pacemakers
  • Vascular therapy devices
  • Defibrillation devices
  • Stents and guidewires
  • Implantable conductors
  • Biosensors and monitors
  • Orthopedic wires
