The Sir-Chem* Dry Powder 63 (BLACK) is a high-quality, nonfluorescent black magnetic particle inspection (MPI) material specifically designed for use in the dry method of detecting surface and near-surface discontinuities in ferromagnetic materials. Manufactured by Circle Systems, a trusted leader in NDT consumables, this powder is supplied in a convenient 10 lb. jar, providing a substantial quantity for repeated and extensive magnetic particle inspections.

In the dry MPI method, a magnetic field is induced in the ferromagnetic test piece. Where discontinuities such as cracks, laps, seams, or inclusions are present, they disrupt the magnetic field, causing magnetic flux leakage fields to form at the surface. When the Sir-Chem* Dry Powder 63 (BLACK) is dusted or otherwise applied to this magnetized surface, the finely divided black magnetic particles are strongly attracted to and accumulate at the locations of these flux leakage fields, visually outlining the shape and extent of the discontinuities.

The black color of this powder is intended to provide excellent contrast against a variety of lighter-colored test surface finishes, enhancing the visibility of indications under appropriate lighting conditions (typically visible light). The formulation of Sir-Chem* Dry Powder 63 (BLACK) is engineered for optimal particle size and magnetic permeability, ensuring reliable detection of even fine flaws with good particle mobility and buildup at defect sites.

The 10 lb. jar packaging offers a practical solution for storing and dispensing the powder, helping to maintain its quality and preventing contamination.

Important Note Regarding Color: While the product name clearly states "(BLACK)," general information commonly available for "Sir-Chem Dry Powder 63" describes it as a red magnetic powder. It is recommended to verify the actual color of the product upon receipt and refer to the specific product data sheet from Circle Systems for confirmation of the black variant's properties and intended use.
