The constant increase in human life-expectancy is leading to an ever greater demand for implants and medical appliances. As these implants may remain in the body for 15 years or longer and are subject to constant cyclic stresses, high demands are made on the quality of materials used as well as on their internal and external surface structures.

High-tensile metals such as stainless steels, cobalt alloys and above all, titanium alloys are the material of chioce, but special ceramics are also are used. All of these materials are difficult and costly to machine.  Light-weight magnesium is expected to gain popularity as an absorbable implant material for medical applications.  This material poses new challenges during machining in the presence of metalworking fluids

The materials used in body implant parts pose considerable challenges to metalworking fluids. Particular attention has to be given to material compatibility, foaming, high-pressure stability and lubricity. FUCHS provides a fluid designed for each of these material applications.
