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, Hot Isostatic Pressing, Sand Cast or Vacuum Cast Processes. Used throughout aerospace, automotive, chemical food processing, glass, marine, oil & gas, power generation and steel industries.
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.
Hot Isostatic Pressing – forms pore free bars or tubes with a fine grain homogeneous structure that enhances the physical properties of the cast alloy.
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.
All components can be offered in the as cast, proof machined or finish machined condition.
Machining facilities include:
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 4, 5, 56 and 6 Alloys contain Chromium Boride crystals making the alloys extremely resistant to abrasive wear.
The Wallex family of cobalt alloys is used primarily for all wear applications. Wallex is a Cobalt-Chromium-Tungsten formulation which achieves exceptional high temperature corrosion resistance while maintaining hot hardness at elevated temperatures.
Many customers have applications that require specific alloys in order to achieve required properties.
Wall Colmonoy’s expert technical team and state-of-the-art facilities are able to meet specific customer requirements. Powders can be Gas or Water atomised and produced to specific alloy formulations.
