COP, a new alloy for surgical implants.

Y Sunami, E Ishikawa

    Acta Medica Okayama
    |February 1, 1977
    PubMed
    Summary

    A new alloy, COP, offers superior strength, corrosion resistance, and complex shapeability for surgical implants. Developed as a cost-effective alternative to Vitallium, COP addresses limitations of current materials used in Japan for internal fracture fixation.

    Area of Science:

    • Biomaterials Science
    • Metallurgical Engineering
    • Orthopedic Surgery

    Background:

    • Vitallium is a common casting alloy for surgical implants and complex instruments.
    • Current 18-8 Mo alloys used in Japan lack sufficient strength and exhibit corrosion issues for long-term skeletal implants.
    • There is a need for advanced materials for internal fracture fixation instruments in Japan.

    Purpose of the Study:

    • To develop a novel alloy with enhanced corrosive resistance and strength for surgical implants.
    • To create a material suitable for complex shapes, addressing limitations of existing alloys.
    • To find a cost-effective alternative to Vitallium for orthopedic applications.

    Main Methods:

    • Development of a new alloy (COP) with specific elemental composition (20% Cr, 20% Ni, 20% Co, 4% Mo, 0.2% P).
    • Evaluation of age-hardening properties due to phosphorus (P) content.
    • Assessment of mechanical properties including yield point, tensile strength, toughness, elongation, and reduction of area.
    • Testing of corrosive resistance and machinability in molten and heat-treated states.

    Main Results:

    • The developed COP alloy exhibits excellent age-hardening characteristics.
    • COP demonstrates superior yield point, tensile strength, and toughness compared to Vitallium.
    • The alloy possesses high corrosive resistance and excellent machinability.
    • COP is significantly more cost-effective than Vitallium.

    Conclusions:

    • COP is a promising new alloy for surgical implants and internal fracture fixation instruments.
    • Its balanced properties of strength, corrosion resistance, and manufacturability make it a viable Vitallium alternative.
    • COP addresses the critical need for advanced, affordable biomaterials in Japan's orthopedic field.
