Description

Black-Oxide is a black magnetic powder suspended in highly refined light petroleum oil. The particles respond to magnetic leakage fields created by cracks and other flaws. They rapidly collect at such fields producing black lines that reveal and profile flaws. Black-Oxide complies with low sulfur and low halogen requirements.

Special Features
    1. Low background for assured indication visibility.
    2. Particle concentration of aerosols meets requirements.
    3. Black-Oxide can be used with both stationary and portable magnetic test equipment.
    4. Black-Oxide can be used in the shop or in the field.
    5. Black-Oxide spray cans offer conveniences and improve reliability since the pressure
      spray evenly disperses the particles in a uniform, light oil spray
