Materials
Lost foam casting can be used with all types of ferrous and non-ferrous
materials, including aluminium alloys, nickel alloys, steels, cast irons, copper
alloys, stainless steels.
Tolerances
Lost foam casting tolerance is influenced by the casting material, size, geometry
and structure. In general, a casting tolerance standard of CT8 ~ CT9 can be
achieved for this process.
