The range of MCP alloys include formulations specially
suited to precision modelling and casting below 300°C.
Some alloys with very low melting points are particularly
suited to fragile or delicate mould materials.

MCP Quality

Quality is monitored by an accredited system conforming to ISO 9002. The alloys are produced from high-grade constituents, following strict specifications, with consistency in manufacture leading to low scrap and reject levels.


Precision

The contraction during solidification for some of the recommended alloys is minimal, allowing large patterns to be used without significant shrinkage in the casting. Perfect reproduction of fine detail is possible by choosing an alloy with characteristics appropriate to the particular task.


Viscosity

The alloys listed below are all of low viscosity at the recommended pouring temperatures, which are 30-50° above the top of the melting range. The 'best' temperature depends on casting time, which is largely governed by the details of mould construction, including the material from which it is made and the fineness of detail to be achieved.

Safety & The Environment
The recommended alloys are not classified as 'dangerous' for either carriage or supply. They are easy to handle, and quite safe when the rules for normal handling are observed.
