Spring-hard allround model casting alloy Spring-hard allround model casting alloy User manual Model casting alloy ADORON® FH is a dental extra hard model casting alloy on the cobalt basis. ADORON® FH is free of nickel, cadmium, beryllium and lead and, according to EN ISO 22674, corresponds to type 5 for applications where tool parts require a combination of high stiffness and yield strength, e.g. thin removable partial dentures, parts with thin cross-sections and clasps. Processing recommendation Modeling Guide round wax profiles with Ø 3.5-4mm in the direction of flow of the melt, avoid sharp deflections. Embedding and casting Phosphate-bonded model casting embedding compounds are suitable. Preheating temperature is 950 - 1000°C depending on model and casting machine, for solid plates final temperature is 1050°C. Holding time at the final temperature is 45 - 60 minutes, depending on muffle size and filling degree of the furnace. Follow the manufacture’s operating instructions for the casting machine. Use separate ceramic crucibles for ADORON® FH to avoid contamination by other alloys. Clean crucible after each casting. Do not overheat the alloy. Casting can be started after all cylinders are completely melted and the melt becomes uniformly bright. Always melt with the flame in the reducing zone with circular movements above of the burner. Allow muffle to cool down to hand temperature and bed out without hitting the cone.
