Bimetal Strip

  • STL manufactures bimetal strips from a proprietary cold-cladding process. Configurations include Inlay, Edgelay and Throughlay. Base materials are Copper and Brass with options of Silver alloy stripes.
  • An STL developed proprietary cold-cladding process now enables us to produce AlCu Aluminium-Copper inlay bimetal strip along with the traditional SilCu Silver-Copper products. Many variations and permutations are possible.
  • The innovative Aluminium-Copper bonding technique now has great potential for busbar technology found within the battery packs of electric vehicles.

Our processes:

Our cold-clad process allows for very thin silver layers to be deposited with pinpoint precision minimising the amount of precious metal needed.

Our unique throughlay process provides the fuse industry with an alternative product to solid silver with a significant reduction in direct costs. The use of seam welding is now obsolete as Brass Silver inlay has been successfully developed. Hot bonding is also used for micro-profile tape and other similar applications for smaller sizes and volumes.

Any of these products can be supplied in large accurately dimensioned coils for your own stamping operation, or more cost effectively, we can manufacture the final component, delivering a quality, ready-to-use product with scrap management inhouse by STL. This also reduces your inventory and transports costs.

 

  • STL innovation has led to us creating a proprietary cold-cladding process that we can now use to produce Aluminium-Copper bimetal strip (AICu) alongside the precious metal options.
  • The foundation for this was the successful development of a bonding technique that overcomes the challenge of Aluminium’s high reactivity to oxygen which makes it very difficult to bond hot.
  • The innovative Aluminium-Copper bonding technique now has great potential for industry, particularly within busbar technology found within the battery packs of electric vehicles (EV’s) allowing copper to copper and Aluminium to Aluminium welding by the pack producers. Also of course the use of Aluminium as the bulk reduces the weight by almost 5 times.
  • This represents a significant opportunity, given the worldwide transition to EV and ZEV usage.
  • STL are at the forefront of innovating busbar technology and additionally has specific stamping techniques available for busbar manufacture with modular press tooling allowing different configurations to be pre-programmed into the tooling.
