7C Black wet non-fluorescent magnetic powder

7C Black is a highly sensitive wet non-fluorescent black magnetic powder. The black magnetic suspension formulated with 7C Black can provide clear and distinct defect indications, and is especially suitable for defect detection of small or medium-sized finished parts.

7C Black can be mixed with water (with water-based regulator) or oil, and can be used to detect inclusions, joints, shrinkage cracks, tears, delamination, welding cracks, grinding cracks, quenching cracks and fatigue cracks.

It is recommended to use with WCP-2 white contrast enhancer to further improve contrast and detection sensitivity.
