Abstract:
An alloy for fabricating plastic molds consisting essentially of between about 0. 4 and 2. 0 weight percent beryllium, between about 29. 0 and 33. 0 weight percent nickel, between about 0. 4 and 1. 0 weight percent iron, between about 0. 4 and 1. 0 weight percent manganese, between about 0. 05 and 0. 3 weight percent zirconium, between about 0. 05 to 0. 30 weight percent titanium, and the balance copper. Plastic injection molds fabricated from said alloy are able to withstand the corrosive conditions present when fire retardant plastics are formed and are able to reproduce pattern detail completely and accurately.
