PCD Grades and Characteristics
Perfect where extreme chip resistance is required, such as in milling and rough cutting of aluminium alloys, and for machining titanium and composites.
Sub-micron grain size. The ultra-fine grain structure of CMX850 is ideal for applications that require mirror finishes, thanks to its strong edge sharpness/retention.
Best for use in thread cutting tools and profile routers. CTX002 can additionally be applied in wear part applications.
Average grain size of 2 µm with ease of processing facilitated by increased cobalt. CTX002 is ideal where excessive processing is required, as in complex tools.
Ideal for aluminium alloy cutting which requires a high surface finish, as well as higher durability.
4 µm average grain size. The 4-micron fine grain structure of CTB004 provides an extra facet in delivering the perfect balance between durability against chips and abrasions and optimum tool performance.
Where roughing and finishing are completed with a single tool, CTB010 is the ideal grade. Best for use with low-to-medium content aluminium alloys.
Average grain size of 10 µm. The workhorse PCD grade, CTB010 is widely applicable for tasks requiring a key balance of toughness and durability.
Ideal in tasks involving the machining of metal matrix composites (MMC), high silicon aluminium alloys, ceramics and tungsten carbide.
With a 25 µm average grain size, CTH025 provides maximum wear resistance in harsh machining conditions.
Application areas CTM302 is designed for include bi-metal applications, MMC, high silicon aluminium alloys and high-strength cast irons, thanks to its strong thermal stability and high abrasion resistance.
As a multi-modal PCD, the combination of 2 µm to 30 µm grain sizes in CTM302 provide it with high edge strength and quality, as well as strong wear resistance.
Choosing the Right PCD Grades
PCD Grades for Wider Usage
Thanks to progress in product development capabilities and developments with synthesis techniques, CMX850 and CTM302 possess the properties to overcome many common obstacles in tool performance. CMX850 balances performance with processability, CTM302 is the last word in maximum abrasion resistance, and CTB004 strikes the optimum balance of tool performance and abrasion resistance.
