General
Moldmax HH is a high-strength beryllium copper mould alloy, made by Materion Brush Performance Alloys, for plastics moulding applications. Its main properties include:

• high thermal conductivity

• good corrosion resistance

• good polishability

• good wear resistance

• good resistance to galling

• good machinability

• high strength and hardness

• excellent weldability

Moldmax HH is widely used for injection moulding tools or as cores and inserts in steel moulds. When used in steel mould it effectively cools hot spots, reducing or eliminating the need for cooling channels.
Moldmax HH is available in wrought round and flat section, machined core pins, and welding wire.
Moldmax HH's high thermal conductivity, 3 to 5 times better than steel, ensures uniform, rapid heat removal, minimizing part distortion, warpage, poor replication of detail and similar defects. In many cases it can significantly reduce cycle times, even when used in a steel mould just for selected cores and inserts.

Applications
The special properties of Moldmax HH beryllium copper alloy make it a suitable mould/core/insert material for a wide variety of moulding situations but especially where a combination of high thermal conductivity, corrosion resistance and good polishability are needed.

• Blow moulds: pinch offs, neck rings and handle inserts

• Injection mould: moulds, cores, inserts

• Injection nozzles and manifolds for hot runner systems
