Integrated Engineering Supply

Copper Alloys operates a fully integrated supply programme from which it's customers can pick and choose the support level they need.
Support Level 1 - Raw Materials

Manufactured to order, Copper Alloys is a leading producers of high integrity exotic materials, which can be supplied in a form ready for further processing. Materials produced to any specification:  
  • Hot/Cold Forging - GFM, Press Forging and Hand Forging
  • Heat Treatment
  • Drawing and Extruding
  • Cold Forming
  • Pressing
  • Rolling
  • Continuous casting
  • Sand casting

  • Bar
  • Shafts
  • Flanges
  • Pipe
  • Plate
  • Blocks
  • Rings

Custom sections
Support Level 2 - Proof and finished machined components   The key to a high integrity component is the material from which it is manufactured, so it is important that the same level of integrity is continued throughout the production process.   Copper Alloys has a number of automated CNCs and manufactures components to print, in any of the materials from Level 1, the more complex and critical, the better.   Remove the risk of a loss in integrity and let Copper Alloys supply components, packed and fully certified.     Support Level 3 - Project Management Copper Alloys has the technical competencies and quality management systems to manage the production and supply of whole engineering projects.
Supporting engineering on a global scale, working with Copper Alloys to Support level 3 will yield the following benefits:  
  • Effective risk management by delivering on time and in full
  • Guaranteed integrity of components and systems
  • Continuous metallurgical improvement
  • Reduced costs through outsourcing the supply of complex projects
  Testing & Certification   Underpinning all levels is Copper Alloys competitive advantage, which is the ability to supply detailed certification packs and supporting documentation to ensure the integrity of all products supplied, from raw material to whole projects. Copper Alloys holds the ISO AS9100 quality approval, which is the highest level achievable by a manufacturer. This has been scrutinised by defence organisations around the world and is continuously updated, revised and improved to ensure full compliance with the latest requirements in quality.   Testing methods include:
  • Mechanical Testing
  • Fracture Toughness & Fatigue Testing
  • Chemical Testing
  • Ultrasonic Testing
  • Dye Penetrant Testing
  • Metallographic & Hardness testing
  • X-Ray Testing
  • Corrosion Testing

Wrought Products

From our casting of billets and slabs, we can offer semi-manufactured wrought products and fully finished components in non-ferrous alloys, particularly to aluminium bronze and cupro nickel specifications.

All of our forging's are made from the highest quality virgin materials that are cast into a billet and then forged to your specific requirements.   We can also machine them!
We can convert the cast structure of our billets and slabs through thermo-mechanical working operations, to produce wrought products. There are a huge number of different processing operations, such as forging, rolling and extruding. We can after hot working an alloy, manipulate the final microstructure and mechanical properties through heat treatment, optimising the alloy for a particular application. Our wrought products are superior to cast products. They are characterised as having:
We manufacture an entire range of wrought copper alloy products, in all the major alloys, using a variety of mechanical working operations as follows:  
  • Forging (press / hammer / GFM) - bars, stepped shafts, discs, boss forging's, flanges, blocks, rings, precision rotary forged bars.
  • Extrusion - rods and bars, round, square, flat, profiles.
  • Hand rolling - rods and bars, round, square, flat, profiles.
  • Hot Rolling - Plates and sheets

We can complement these operations with down-steam cold drawing, heat treatment, grinding, peeling and machining operations (conventional and CNC). We are able therefore to offer semi-finished wrought products, or supply finished components.
Our capacity in terms of maximum component weight continues to grow as we invest in our casting facility in Stoke.
