Tru Temp® Black Oxide Finish Is Ideal For Machine Tool Components – It’s Durable, Attractive And Resists Corrosion With Many Application Benefits

TRU TEMP® Black Oxide

High value tooling such as toolholders, workholding and turret press tooling takes on an attractive, protective black oxide finish when finished with the Tru Temp low temperature, non-polluting black oxide system from Birchwood Technologies.

Extremely durable, the Tru Temp process provides a satin black magnetite coating, 20 millionths thick (0.54 micron) with no effect on component material hardness or tensile strength.
