What is a Cryo-Treated Brake Rotor?

Thursday, August 15, 2013 by Zig Ziegler

When shopping for the best brake rotors for your vehicle you've probably come across the term "cryo-treated." Since this technology is relatively new in the brake component market, many have never heard of the term or know what it means.

Cryo-treated rotors are actually cryogenically treated in addition to standard heat treating. Deep cryogenic treating is a one-time, homogenous process that permanently and dramatically improves the performance and useful life of metals in everything from brake rotors and performance engines to machine tools and gun barrels. Using a proprietary computer-controlled process, the metal is cooled slowly to deep cryogenic temperatures (-300°F), and slowly returned to room temperature, then heat-tempered as the final step. Computer technology allows the regulation of temperatures to 1 degree, accurately manipulating the cryo treatment in accordance with the mass of the part it's being applied to.

Although not apparent to the naked eye, the improvements to the metal are significant. Deep cryogenic processing creates dramatic increases in abrasive wear resistance and durability. The increases in tensile strength, toughness and stability couple with the release of internal residual stresses.

A cryo-treated rotor will be more resistant against wear and warping than conventional heat treated rotors. If you're looking for the most durable replacement rotor with outstanding ability to withstand warping, a cryo-treated rotor will definitely be worth the extra expense.

Shop by vehicle to see if there's a cryo-treated rotor for your application.
