Met-L-Chek MPI-86Y is a finely divided, dry magnetic particle powder formulated to provide high contrast indications of surface and near-surface flaws in ferromagnetic materials when viewed under white light. This yellow powder is applied to a magnetized test piece, and the magnetic particles are attracted to magnetic flux leakage fields created by discontinuities such as cracks, laps, seams, and inclusions. The accumulation of the yellow particles at these leakage fields creates a visible indication of the flaw's location, size, and shape.  

Key Features and Benefits:

• Visible Indications: The bright yellow color of the particles provides excellent contrast against most metallic backgrounds when viewed under normal white light conditions.

• Dry Method Application: Designed for dry powder application, typically using a powder blower or bulb, making it suitable for field inspections and situations where wet method application is not practical or desired.  

• High Sensitivity: Formulated to be sensitive to fine discontinuities, providing clear and reliable indications of flaws.

• Wide Range of Applications: Can be used for inspecting a variety of ferromagnetic components and structures in industries such as welding, manufacturing, aerospace, automotive, and more.

• Meets Industry Standards: Met-L-Chek MPI-86Y is formulated to meet or exceed the requirements of industry specifications such as AMS-3040 and ASTM E-1444 for visible dry method magnetic particle inspection.  

• High Temperature Capability: This specific product, MPI-86Y, may be used on hot surfaces up to 800˚F (426˚C), expanding its applicability to inspections performed during or after certain manufacturing processes or in-service conditions.  

• Type 2 Visible Magnetic Particle: Classified as a Visible: Type 2 magnetic particle material according to relevant MPI standards.  

In summary, Met-L-Chek MPI-86Y is a reliable and effective yellow dry method magnetic particle powder used for the detection of surface and near-surface flaws in ferromagnetic materials under white light. Its high sensitivity, contrast, and potential for high-temperature use make it a valuable consumable in various magnetic particle inspection applications.
