Material types
The investment casting technique permits the use of an
almost unlimited spectrum of casting and also wrought
materials. A certain restriction is imposed by the fact that
a large number of materials possess similar characteristics
and be ‘substituted’ by alternative materials which are at
least equivalent in value. On the other hand, investment
casting also permits the use of a higher-grade material at
no additional cost, so covering a wide range of possible
applications. Accordingly, in the following explanation, types
providing a representative selection have been specified
under the various material groupings. If the use of different
materials is stipulated expressly for certain applications, an
enquiry is necessary with the producer. The data contained in
the tables are guideline values only. This applies also where
guaranteed minimum values are specified in standards or
other regulations. As a rule, these regulations refer to other
shaping techniques unless they explicitly specify the instrument
casting method. Unless otherwise indicated, the values
apply to separately cast test bars.
