  • CNC/EDM manufacturing

    Sandvik is well known globally for its experience and expertise in special alloys and metal cutting. The CE alloys team has leveraged this knowledge to develop specialist tooling and processes to produce high-quality components from advanced materials.

    We have a fully equipped machine shop in our UK facility and work closely with a list of approved sub-contractors to offer global manufacturing solutions.

  • Specialist operations

    In addition to CNC/EDM manufacturing, we have developed and manage a wide range of complex supply chains for specialist operations. Examples are:

    • Electrical feedthroughs for packaging applications
    • Diffusion bonding for applications requiring internal cooling channels
    • Cutting and polishing processes for optical applications.

    Our experts are available to work collaboratively to develop a supply chain to support your project.

  • Finishes and coatings

    We offer a wide range of finishes and coatings depending on alloy and application, such as electroless plating, conversion coatings and light-absorbing coatings.
