NGK ULTRA is recognised as an excellent lower conductivity, higher hardness beryllium copper alloy for the plastic industry as injection moulds and tooling for blow moulds. Due to its optimum combination of hardness, wear resistance, thermal fatigue, and thermal conductivity, it is known to produce superior quality plastic parts with minimum total production costs over other competing mould materials.
