Cortem® conductive springs combine the strength and high temperature properties of steel with the conductivity of copper, providing an efficient brush spring and a functional current conductor.

• In many applications, eliminates need for a shunt
• In others, provides a parallel conductor to shunt for maximum reliability
• Increases brush performance by 20 to 30 percent
• Manufactured from copperclad 17-7 PH stainless wire
• Provides excellent mechanical and electrical properties
• Available in a wide range of wire sizes, spring dimensions and configurations
• Available in two conductivities:
• 30 percent and 40 percent
• Utilizes CortiteTM construction in attaching spring to brush
• Insertion of spring into hole in head of brush
• Prevents brush head from loosening
• Usable brush length is extended by depth of the hole
• CortiteTM spring/brush assembly can be automated vs. hand assembly
• Kirkwood can custom design springs to fit operating parameters
