MOLDMAX HH

MoldMAX HH (high-hard) is a high-strength beryllium copper mold alloy, made by Materion Brush Performance Alloys, for plastics molding applications.

This alloy has a hardness and strength comparable with standard tool steels but its thermal conductivity is at four to six times higher.

MoldMAX HH is used for injection mold cores and cavities and blow mold pinch-offs.  Its high hardness provides durability in applications where other high conductivity copper alloys fail.  The alloy also resists galling against other mold alloys, including itself.

Product Features:

• High thermal conductivity
• Good corrosion resistance
• Good polishability
• Good wear resistance
• Good resistance to galling
• Good machinability
• High strength and hardness
• Excellent weldability

Applications:

• Injection nozzles and manifolds for hot runner systems
• Inserts
• Neck rings and handle inserts
