EvoCera® - High-precision, dimensionally stable high-performance ceramics with steel character for clamping technology, sensor technology and pharmaceutical and food applications (FDA-compliant design possible)
EvoCera® - Ceramic innovation from Doceram, available from Megatron AG
EvoCera® is a new type of high-performance material that combines the advantages of modern technical ceramics with the ductile properties of steel. Developed by Doceram and available from Megatron AG, EvoCera® opens up new possibilities in safety-critical areas where metallic materials have dominated until now.
In contrast to conventional industrial ceramics, EvoCera® has an extremely low scatter in material strength - thanks to a significantly increased Weibull modulus (> 50). This makes it possible for the first time to precisely calculate and design ceramic components using FEM (finite element method) - a process that was previously used almost exclusively for steel materials.
Ceramic power reserves for safety-critical applications
EvoCera® remains dimensionally stable and fracture-resistant even under continuous cyclic loading. Thanks to its plastic-ductile properties, the material cannot fail abruptly under overload, but exhibits predictable, transformation-controlled deformation behavior. This "residual reserve" makes EvoCera® ideal for safety-relevant constructions.
