Moldmax XL is a high-strength, high thermal conductivity copper alloy manufactured under patents by Brush Wellman Inc.. It is intended for use in a wide variety of plastic injection moulds. Its main properties include:

• high thermal conductivity

• excellent machinability

• good corrosion resistance

• good wear resistance

• high impact strength

• excellent resistance to galling

• large cross sectional availability.

Moldmax XL combines high levels of strength and thermal conductivity. It effectively reduces hot spots, minimizing cycle times and improving as-moulded part tolerances.

Moldmax XL has consistent hardness throughout even the largest cross section, providing predictable strength in deep sections and excellent machinability. At the same time it offers impact strengths suitable for complex designs.

Applications
Moldmax XL is designed to be used primarily for core inserts in larger injection moulds. Tools incorporating Moldmax XL inserts provide numerous advantages to both the mould maker and injection moulder.
