Grey Iron MF2
Flocast MF2 has Type D graphite in a ferrite matrix. This specification was developed for the glass mould industry where a fine grain struture and superior machining finish are needed. Dimensional growth due to repeated heating and cooling cycles is minimal due to the smaller graphite flake size and ferritic matrix structure.
The micro structure will contain D type size 7 - 8, graphite. The matrix is ferrite with less than 10 % pearlite.
