Typical values are mean results on compression-moulded and sintered test plaques made in the laboratory unless a method says otherwise. Properties of a finished part depend on the moulding or ram-extrusion route, the sintering cycle and the direction of flow. Limits apply to lot release. They are not a warranty of fitness for a particular use. Confirm suitability on your own counterface, fluid and temperature.
