From our casting of billets and slabs, Copper Alloys Ltd can offer semi-manufactured wrought products and fully finished components in non-ferrous alloys, particularly to aluminium bronze and cupro nickel specifications.
All of Copper Alloys Ltd's forgings 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!
Copper Alloys Ltd 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:
- Higher strength and impact toughness
- Greater soundness and integrity
- Fine grain structure leading to better corrosion performance
- Fine grain structure allowing detailed ultrasonic inspection rather than expensive radiography
- Grain flow giving directional properties that can be used by designers to their advantage
Copper Alloys Ltd 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 forgings, 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 here in Stoke.
