Pourable core materials offer alternatives to preformed cores. R&R’s core materials are specifically designed to be used with the ceramic shell casting process.

C-1 Core Mix
C-1 core mix is used to make preformed cores for use with ferrous castings. C-1 core mix is exothermic as it sets; which, in most cases, prevents it from being used in direct contact with wax patterns. If the core is small, such as with a golf club hosel, you can form the core against the wax pattern without damage to the wax.

50/50 Core Mix
50/50 core mix is used to hand pack cores and is typically used by ferrous casters. 50/50 core mix is exothermic as it sets; which, in most cases, prevents it from being used in direct contact with wax patterns. If the core is small, such as with a golf club hosel, you can form the core against the wax pattern without damage to the wax.

Core Hardener 2000™ Binder
CORE HARDENER 2000 binder is a water-based colloidal silica binder used to strengthen the ceramic shell in small holes, slots and hard-to-reach openings. It helps prevent metal penetration by strengthening the shell; which is usually thin in these areas. CORE HARDENER 2000 binder can also be used to strengthen C-1 core mix, 50/50 core mix and 910 investment core materials.

Kwik-Core™ Binder & Investment
KWIK-CORE binder and investment is a binder and powder system that is designed for hand packing cores to be used with ceramic shell. KWIK-CORE binder and investment is for use primarily with ferrous castings. Due to its low exothermic reaction, KWIK-CORE binder and investment can be poured directly into the cavity of the wax.

910 Investment Core Material
910 investment core material is a calcium sulfate bonded investment for cores. It is used with non-ferrous alloys which do not exceed temperatures of 2200°F (1200°C). 910 investment has good green strength, good thermal shock resistance, is easily removed after casting and can be used directly in contact with the wax pattern.
