Duplex Aluminium / Copper-Nickel laminates: shielding and insulation solutions

Alu / Copper duplex laminates are multi-layered technical materials designed to ensure a high electrical insulation, effective EMI shielding and long-lasting protection of industrial components. Thanks to the combination of an aluminium layer and a copolymer, they offer an excellent compromise between conductivity, protection and mechanical resistance.

Particularly used in demanding environments, these laminates allow systems to be secured against electromagnetic interference, electrical constraints and severe environmental conditions.

At ADDEV Materials, we support manufacturers in the custom selection and transformation of technical laminates, in order to optimise their performance and integration into applications.

Structure and composition of laminate

The Alu/CoPo laminate is based on a simple yet effective structure:

  • aluminium → conduction et blindage EMI
  • copolymer → insulation and adhesion

This combination results in a reliable and versatile technical material.

Duplex laminates are distinguished from more complex laminates:

  • Duplex → 2-layer, simple and high-performance solution
  • 3 layers, enhanced performance but more complex

The duplex is preferred for applications requiring a good balance between performance and cost.

What is an Alu / CoPo duplex laminate

A duplex Alu / CoPo laminate is a material composed of two layers:

  • An aluminium layer ensuring conductivity and shielding
  • a copolymer layer providing insulation and protection

This structure makes it possible to combine:

  • High electrical properties
  • mechanical strength
  • Environmental protection

This is an ideal solution for applications requiring multi-layer performance.
