    Low Melting Point Alloys

    Base Alloy

    Base Alloy is one of the eutectics, i.e. it has a sharp melting point (124°C). Unlike Bend Alloy, Tool Alloy and Press Alloy, which expand immediately on solidification, Base Alloy first shrinks and then grows slowly, reaching the dimensions of the mould some 5 – 7 hours after casting. This characteristic is of value since castings can be removed easily from the mould and measurements taken accurately when the casting has reached mould dimensions. It is also useful as a bending medium instead of Bend Alloy where the latter’s expansion characteristic is too great.

    Base Alloy is manufactured from virgin metals and is guaranteed to give complete satisfaction under normal working conditions.
