A special investment for non-precious and semi-precious alloys. Hi-Temp contains no carbon. Non-precious metal alloys require an investment specially compounded to: • Compensate for alloy shrinkage • Withstand high-fusing temperatures • Provide a non-contaminating atmosphere • Allow casting of a lighter-density metal Hi-Temp is the investment with these characteristics and more. It gives a smooth surface to the casting, flows readily and evenly for fine detail and sharp margins, and has high strength to prevent damage to the mold.
