ABSTRACT:
The present invention provides aluminum bronze glassmaking molds. The molds are substantially free of zinc and lead, consist essentially of manganese, nickel, iron, aluminum and copper, and exhibit superior wear resistance, durability, pitting and oxidation resistance, and machinability as compared to prior art glassmaking molds. Further, the aluminum bronze glassmaking molds of the present invention have a heretofore unavailable range of thermal conductivities at elevated temperatures so as to optimize the rate of glass forming in, e.g., Hartford Individual Section glass forming machines.
