Met-L-Chek MPI-86R 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 red 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 red particles at these leakage fields creates a visible indication of the flaw's location, size, and shape.
Key Features and Benefits:
Visible Indications: The distinct red color of the particles offers good contrast against most metallic backgrounds when viewed under standard white light conditions.
Dry Method Application: Designed for application as a dry powder, typically using a powder blower or bulb, making it well-suited for field inspections and situations where wet method application is not convenient or preferred.
High Sensitivity: Formulated to be sensitive to fine discontinuities, providing clear and reliable indications of flaws.
Wide Range of Applications: Suitable for inspecting a variety of ferromagnetic components and structures across diverse industries, including welding, manufacturing, aerospace, and automotive.
Meets Industry Standards: Met-L-Chek MPI-86R 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-86R, is designed for use on hot surfaces up to 800˚F (426˚C), expanding its applicability to inspections performed during or immediately following certain manufacturing processes or in-service operations.
Type 2 Visible Magnetic Particle: Classified as a Visible: Type 2 magnetic particle material according to relevant MPI standards.
Specific Properties: The powder has a density of 2500 g/L and a particle size ranging from 15 to 160 micrometers (µ). It also exhibits an SAE Relative Sensitivity of 6.
In summary, Met-L-Chek MPI-86R is a reliable and effective red 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, high-temperature capability, and defined physical properties make it a valuable consumable in various magnetic particle inspection applications.
