          Industrial Aluminum Extrusion Profile Electrical and thermal performance often fail in real projects. Many teams choose aluminum profiles without checking conductivity. This causes heat build up, signal loss, or safety risk. These problems are costly and hard to fix later. Aluminum extrusion conductivity requirements depend on electrical use, thermal load, alloy choice, and surface treatment.
