Description
Laminated Magnetic Flux Strips, also known as Type G Burmah-Castrol Strips, have a core of high permeability steel with brass cladding 0.002 in / 0.05 mm thick on both sides. The core material has three slots of different widths, providing discontinuities that show as linear indications in a magnetic field. The strips are commonly used with wet visible materials for power pack equipment and yoke inspections, but can also be used with dry magnetic powders.
Laminated Magnetic Flux Strips are stiffer than QQIs, and do not conform to curved surfaces easily. But unlike QQIs, Laminated Magnetic Flux Strips are not permanently affixed to a part so they can be reused for multiple applications. Because they form linear indications in only one direction, Laminated Magnetic Flux Strips are not suitable for use with multi-directional magnetization.
