BERYLLIUM COPPER - E-CATALOGUE

World Class Quality For A Global Marketplace 4 NGK PLUS, SUPRA and ULTRA Products are recognized as excellent mold alloys for the plastic industry as injection molds and tooling for blow molds. They are known to produce superior quality plastic parts with minimum total production costs over other competing mold materials. This is due to its optimum combination of hardness, wear resistance, thermal fatigue, and thermal conductivity. Plate products are available in three grades from two alloy systems: PLUS is a higher conductivity, lower hardness beryllium copper alloy. SUPRA is a medium conductivity, medium hardness beryllium copper alloy. ULTRA is a lower conductivity, higher hardness beryllium copper alloy.
