About Circle Systems
Circle Systems has been developing and manufacturing magnetic inspection particles for over 40 years. Magnetic particles are our primary business. Originally named Circle Chemical Co., we have been rooted in the chemistry of magnetic particle inspection since our early days. Our approach has led to products that utilize state of the art chemical technologies, best in class manufacturing methods, and a broad product line that is unmatched in our industry. Circle Systems has established our reputation as a trusted supplier to some of the most notable manufacturers and nondestructive testing companies around the world.
Circle Systems designs our 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. We have eliminated harmful propellants from our CircleSafe® aerosol products. Our dry powders include a line of bonded products to reduce airborne dust from the inspection process. Our commitment to worker and environmental safety is not just a catch phrase, it is a genuine business model that is reflected in our products now and into the future.
We are ISO 9001:2015 certified for the manufacture, supply and research and development for the process of non-destructive testing.
