The NGK Ultra Supra II Plus enable high-cycle plastic forming, improves quality, and ensure a long life for casting mols. NGK Ultra Supra II Plus Features ------------------- thermal conductivity and ----- temperature hardness, the ------------- beryllium-copper alloy ------ the following features as casting mold material used for plastic forming Machinability While this material offers cutting performance Similar to steel of quality hardness, even behalf performance can be achieved by slightly changing the maching conditions.
