A highly refined and bonded nonfluorescent gray magnetic powder used for dry method magnetic particle inspection. It is designed to be used in visible light to reveal discontinuities on fabricated components or weldments such as bridges, drill pipes, large tanks and machinery. This specially bonded iron based powder is designed to minimize “dustiness” and provide clear, sharp discontinuities. The decrease in dusting allows for a safer inspection area. It meets or exceeds AMS 3040 and all applicable industry specifications.
