Beryllium Copper Rod and Plate For The Plastics Industry


Berylco Plus, Supra and Ultra products are designed with one goal in mind. Improved profit through improved performance. Plate products are available in three grades from two alloy systems:

Berylco Plus - higher conductivity, lower hardness beryllium copper alloy.

Berylco Supra - medium conductivity, medium hardness beryllium copper alloy.

Berylco Ultra - lower conductivity, higher hardness beryllium copper alloy.


Berylco products are recognised as excellent mould alloys for the plastic industry as injection moulds and tooling for blow moulds. They are known to produce superior quality plastic parts with minimum total production costs over other competing mould materials. This is due to its optimum combination of hardness, wear resistance, thermal fatigue, and thermal conductivity.

Berylco Plus, Supra and Ultra Performance Attributes


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.

Beryllium Copper, with its high thermal conductivity compared to steel, offers significant advantages in minimizing part distortion, dimensional control and cycle time.

Superior thermal fatigue and strength allows longer tool life and less down-time.

Higher productivity and cost effectiveness.

Excellent resistance to the corrosive by-products of molding operations such as hydrochloric acid. This property makes Berylco Plus, Supra and Ultra plate the mold material of choice for PVC and other corrosive resins.

Filled resins have a higher than normal tendency to wear mold materials. Plus, Supra and Ultra plate competes favorably with most steel in wear applications and it can be plated with nickel and chromium to further enhance performance.

The high strength and wear resistance of Berylco Ultra plate provides superior performance at neck and thread areas, as well as bottoms, when combined with other mold materials.

Beryllium copper inserts and molds can be joined and/or repaired by resistance welding, TIG and MIG welding. However, precautions must be taken against softening and oxidation of the material. Filler metal of the same alloy should be used and oxides, oil and dust should be removed from the parts prior to welding.
