The new Heraeus Copper core Aluminum wire combines the advantages of Aluminum and Copper within one wire. The material mix of Aluminum and Copper provides excellent electrical and mechanical properties and can be used on standard Al-Chip surfaces to improve power density and module lifetime.

In this session, Heraeus will discuss how replacing aluminum wire with its CucorAl Plus, manufacturers can extend module lifetime by a factor of five without changing the module design. This specifically caters to the e-mobility industry needing new materials and components that function in demanding environments. CucorAl Plus enables higher power density within the module design by fusing current capabilities and providing a 20 percent higher ampacity. The wire is designed for operation temperatures of up to 200 °C. It also has better mechanical properties compared to aluminum wire.
