Aluminum that has been strengthened with the addition of silicon and silicon carbide is very abrasive material to cut and has a detrimental effect on the life of cutting tools. The super-hardness of DiaTiger® Diamond is a good coating choice for protecting solid carbide end mills, drills and inserts cutting aluminum-silicon alloys. DiaTiger® Diamond Coated tools also allow for special tool geometry to be incorporated into the tool design to address chip control problems.

Diamond Tool Coating collaborated with the National Center for Defense Manufacturing & Machining to help Lockheed Martin Missiles and Fire Control (LMMFC) gain a more efficient solution to machining Metal Matrix Composite (MMC). The most common MMC is cast aluminum reinforced with various amounts of silicon carbide. View Full Report
