Precision Components

    An Integrated Approach – Casting, Heat Treating and Machining All from One Source

    Engineered cast or fully machined components are designed to optimize wear, corrosion, abrasion and heat resistant properties. Made from Colmonoy®, Wallex® or customer-specific alloys using Investment, Centrifugal, Sand Cast, Vacuum Cast or Hot Isostatic Pressing (HIP) Processes. Used throughout aerospace, automotive, chemical food processing, glass, marine, oil & gas, power generation and steel industries.

    Casting Methods

    Investment – offers design flexibility, close dimensional control, consistency & repeatability, cost savings.

    Centrifugal or Spin – is used to produce high integrity densely structured, cylindrical components like bushes and sleeves.

    Sand – is typically used to produce larger components in smaller batches. It is capable of making mostly complex shapes using relatively inexpensive wood or resin patterns.

    Vacuum Casting – is used for alloys where tight compositional control and low inclusion counts are required – difficult to achieve when using conventional air melting and casting.

    Hot Isostatic Pressing – forms pore free bars or tubes with a fine grain homogeneous structure that enhances the physical properties of the cast alloy.


    Full range of machining needs

    All components can be offered in the as cast, proof machined or finish machined condition.

    Machining facilities include:

    • Milling – CNC and Manual
    • Turning – CNC and Manual

    Colmonoy ®

    Nickel-based Alloys

    The Colmonoy® family of Nickel, Chrome Boron Alloys offer superior wear protection, retaining their hardness up to 600ºC (1000ºF) while maintaining significant resistance to oxidation and corrosion. Colmonoy® 30D, 40D, 40G, 5 and 6 Alloys contain Chromium Boride crystals making the alloys extremely resistant to abrasive wear.


    Wallex ®

    Cobalt-based Alloys

    The Wallex® family of cobalt alloys is used primarily for all wear applications, particularly Wallex® 4 and 12. Wallex® is a Cobalt-Chromium-Tungsten formulation which achieves exceptional high temperature corrosion resistance while maintaining hot hardness at elevated temperatures. Wallex® 20/1040 is highly suitable for Food and Canning applications, whilst Wallex® 180 and 6 has extensive use in Steel Industry galvanising process applications, where corrosion is a factor.
