MagnaFlux Magnavis 7C Black Wet Method Colored Nonfluorescent Magnetic Particles

7C Black is a highly sensitive magnetic particle powder designed for nonfluorescent (visible) wet method magnetic particle testing. Suspensions made with 7C Black offer clear, strong indications, making them ideal for detecting fine and medium discontinuities on finished parts.

7C Black can be mixed with water or oil to detect inclusions, seams, shrink cracks, tears, laps, flakes, welding defects, grinding cracks, quenching cracks, fatigue cracks, and other imperfections.

Use with WCP-2 white contrast paint to improve probability of detection and sensitivity.

APPLICATIONS: Detecting fine and medium discontinuities, Difficult to reach areas, Field testing, In-service inspections, Light surfaces, Machined parts, Reflective or light-colored surfaces, Spot inspections

DEFECT EXAMPLES: Fatigue cracks, Grinding cracks, Inclusions, Laps, Quenching cracks, Seams, Shrink cracks, Tears, Welding defects

SPECIFICATIONS COMPLIANCE: AMS 3042, ASME, ASTM E3024, ASTM E709, MIL-STD-2132, MIL-STD-271, NAVSEA 250-1500-1, NAVSEA T9074-AS-GIB-010/271
