The quality of the interface offers considerable advantages to the users of Kugler Bimetal parts with excellent mechanical properties (with partial transfer of load to the steel) and perfect « anchorage » of bronze in thin layers (that allows the thermal expansion of the Kugler Bimetal parts to be kept close to that of the steel in case of heating or thermal shock). This means that, under operating conditions, mechanical clearances can be kept both accurate and constant.
COMPACTNESS
The friction layeris integrated in the part, only where it is needed.
SIMPLICITY
Reductionof the number or dimensions of parts, resulting in substantial economies.
Strength and security
The perfect steel/Tokat bond allows applications at temperatures from -70°C à +250°C (or higher, if the bronze does not contains more than 1% lead).
Great security in use
No galling on steelin the event of a lubrication breakdown Kugler BIMETAL parts act as "self-lubricating".
Ability to alter shapeunder load in order to adapt better to the counter-piece without damaging it (accommodation).
Ability to absorbhard abrasive particles into the friction surface.
Further treatment
The steel/bronze bond is not affected by later heating, up to about +700°C.
In the course of manufacturing, the customer may, therefore:
Weld the steel portion of the Kugler BIMETAL parts.
Carry out treatments to the steel surface, such as nitrating or tempering by induction.
And even, in certain cases, carry out thermal treatments on the whole part.
