Home Products Composite And Clad Metals Copper Aluminum Dovetail Clad® Dovetail Clad Battery Busbar Material COPPER ALUMINUM DOVETAIL CLAD® Busbar Material for Lithium-Ion Battery Packs As the electrification of automobiles moves towards mass production, OEMs are faced with the serious challenge of greatly reducing the cost of their battery packs. Eliminating high-cost manual assembly by using high-speed automated laser welding is the industry trend. However, this poses another challenge: reliably joining dissimilar metals of copper and aluminum terminals and busbars. Materion's Copper Aluminum Dovetail Clad® Solution Cladding copper and aluminum side-by-side eliminates the metallurgical instability of laser welding copper to aluminum by facilitating same metal welding of busbars to terminals. Product Features: Copper Aluminum Dovetail Clad Battery Busbars Superior mechanical, electrical, and thermal performance over ultrasonic and bolted connections. No resistance or thermal rise at Dovetail joint. Dovetail joint strength matches that of the aluminum alloy. Dovetail joint lifetime stability exceeds 20 years at operating temperatures below 200oC. Narrow joint widths (4mm max) Product Benefits: Reduce pack assembly cost Continuous master coils compatible with high-volume stamping Dovetail joint can easily be formed into compliant busbars Availability: A91100, A93003 C10200 - with or without Nickel or Tin plating Thicknesses 0.1mm up to 2.0mm Widths up to 165mm Contact Us today to speak with one of our engineers about this unique clad metal solution for Busbars.
