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. Components such as gears, sprockets and couplings operate with no functional change while the finish adds substantial protection. Tests verify Tru Temp withstands up to 100 hours of neutral salt spray (ASTM B 117) or several hundred hours of humidity (ASTM D 1748).
