Aluminium oxide ceramic is mainly constituted of aluminium oxide. These materials pass through hot compacting and machining operations during manufacturing of the medical devices that integrate them.
These materials are favoured to constitute articulation pieces, for they have an excellent friction coefficient.
ISO 13356
Zirconia ceramic is mainly constituted of zirconia oxide stabilised with yttrium oxide. These materials pass through hot-compacting and machining operations during manufacturing of the medical devices that integrate them.
These materials are favoured to constitute articulation pieces, for they have an excellent friction coefficient.

Very high molecular density polyethylene is an ethylene polymer constituted of carbon and hydrogen. It comes in powdered form (ISO 5834-1) or in moulded form (ISO 5834-2).
These materials pass through hot-compacting and machining operations during manufacturing of the medical devices that integrate them.
Because of their tribological properties, these materials are favoured to manufacture concave articulation pieces.
