High-conductivity Materials for Aluminum Busbars

Replacing copper with aluminum drastically reduces weight and cost.

Features

Aluminum busbars weigh and cost far less than copper busbars.
The EC1 alloy exhibits the same high conductivity as pure 1050-O aluminum and 1.5 times its strength.
EC2 has only 55% of the conductivity of copper (lower specification limit) but exhibits the same level of conductivity when it is 1.8 times thicker.
