Magnaflux 7HF Black Ink (Carton of 12)

Oil-Based Visible Magnetic Particle Suspension
7HF is a highly-sensitive oil-based magnetic particle suspension aerosol for nonfluorescent (visible) wet
method magnetic particle testing. 7HF provides clear, strong indications and are ideal for locating fine
and medium discontinuities on finished parts. It is ideal for field testing, spot inspections and places
where bulk processing is impractical.
7HF is often used with WCP-2 white contrast paint to improve contrast and inspection sensitivity. This
process is ideal for remote inspections of tubing, piping and large structures.

BENEFITS
Maximize indication detection
• Find indications of all shapes
and sizes thanks to the smallest
particle on the market
• Heavy buildup of highly magnetic particles

around all leakage fields make for heavy-
contrast indications, especially when

used with WCP-2 white contrast paint
Convenient to use
• Inspect in all conditions without the
need for darkness or UV lights
• The visible particles come in a
convenient, aerosol format to be
easily carried and used in the field
Wide application versatility
• Inspect a wide range of components
without fear of corrosion or
specification non-conformance

FEATURES
• Clear indications under visible light
• Heavy particle buildup
• Great particle mobility
• Protects parts and equipment against
corrosion
• Broad spray pattern provides even surface
coverage over large areas
• Superior surface wetting
• Very small particle size
