The BK series is a specialized metal backing powder engineered by MBN for use in the diamond tools industry. Based on an iron-nickel granulated alloy, ensuring excellent flowability and compressibility, especially in automated green compaction systems.
The material has been specifically designed to be weldable by automated laser lines and deliver high impact resistance, promoting a strong mechanical bond between the diamond segment and the metal support.
This makes BK815G particularly suitable for demanding cutting and grinding applications where durability and safety are critical.
