Circle MPI Materials

Circle Systems has been developing and manufacturing magnetic inspection particles for over 40 years. Originally named Circle Chemical Co., they have been rooted in the chemistry of magnetic particle inspection since the early days.

Circle Systems designs products with worker safety and environmental protection in mind. Circle has led the way in developing products for use in water based carriers to replace petroleum based chemistry in many applications. They have eliminated harmful propellants from our CircleSafe® aerosol products. The dry powders include a line of bonded products to reduce airborne dust from the inspection process.
