Implant materials

Stainless Steel

Our material portfolio includes implantable stainless steels established on the market. They have high fatigue strength, an excellent degree of slag purity and are biocompatible. We also offer our special material Ergste® 9.9007CN, which is particularly biocompatible due to its lack of nickel. Due to its balanced chemical composition, it combines properties such as excellent corrosion resistance, high static strength and fatigue strength as well as a completely non-magnetic behavior.

Titanium

Semi-finished products made of pure titanium and titanium alloys offer optimized properties. They are corrosion resistant and not magnetic. These materials are highly biocompatible. Due to their lack of nickel, they do not trigger allergies. The elasticity module in titanium comes closest to human bone. Other metallic implant materials do not have this property. In connection with the high fatigue strength, titanium offers an unrivaled high bio-functionality. Compared to pure titanium, titanium alloys have a higher fatigue strength. Pure titanium has a high impact strength and is easy to weld.

Cobalt-based alloys

The special alloys from Zapp Medical Alloys offer maximum strength and wear resistance in combination with very good corrosion resistance and high-gloss polishability. Cobalt-chrome (CoCr) materials are also highly biocompatible.

Instrument materials

Martensites

Martensitic stainless steels combine high hardness and wear resistance with relatively good toughness. They are resistant to corrosion under atmospheric environmental conditions. They are mainly used for blades and knives in medical applications.

Precipitation-hardenable steel

These special alloys have a high formability in the non-hardened state and can achieve very high hardness and strength through precipitation hardening. They are used for complex formed components with very high demands on strength and corrosion resistance.

Austenites

Austenitic stainless steels are characterized in their annealed condition by their high formability combined with very good corrosion resistance. The corrosion resistance can be further increased by adding chromium or molybdenum content. Depending on the nickel content, either higher formability or an a-magnetic material can be achieved. We sometimes find them as implants or connecting elements in our body after surgery.

Ferrites

Depending on the chromium content, ferritic stainless steels can have excellent corrosion properties. They are used wherever good corrosion properties are required but high demands are not placed on formability. By modifying the chemical composition and the manufacturing process, single- or multi-phase structures with special magnetic or other properties can be adjusted and made to measure for the respective application.
