Wear Solutions: Perfect for industrial seals, valves, and components subjected to extreme friction and impact.

Tungsten Carbide Rod Grades Reference Table

Grade	Grain Size Category	Co %	Hardness (HRA)	TRS (MPa)	ISO Code Equivalent	Primary Applications & Targeted Materials
YL10.2 / HF6 (Industry Standard)	Fine / Micro Grain	10%	91.5 - 92.5	3500 - 3800	K20 - K30 (Highly Versatile)	Global Best-Seller. Offers an exceptional balance of wear resistance and toughness. The premier substrate choice for solid carbide end mills, drills, and CNC cutting tools. Ideal for machining carbon steel, alloy steel, and cast iron.
GU25 / KU25 (Premium High-Toughness)	Submicron Grain	12%	91.0 - 92.0	3800 - 4000	M20 - M30 S20 - S30	Features an ultra-fine microstructure with higher cobalt content, providing extreme fracture toughness. Engineered for heavy-duty profiling, interrupted cutting, and difficult-to-machine materials like stainless steel, titanium, and nimonics.
GU10 / KU10 (Premium High-Hardness)	Ultra-Fine Grain	6%	93.0 - 94.0	3200 - 3500	K05 - K10 H05 - H10	The Hardness Champion. Reaches over 93.5 HRA due to its nano-scale matrix. Designed specifically for high-speed finish machining of hardened steels (HRC 45-60), high-wear die components, graphite, and glass-fiber composites.
YG6	Medium / Coarse	6%	89.5 - 90.5	1600 - 1800	K10 - K20	Traditional universal grade. Primarily used for rough milling and turning of cast iron, non-ferrous metals (aluminum, copper), non-metallic materials, or as raw blanks for standard industrial wear components.
YG8	Medium / Coarse	8%	89.0 - 90.0	1800 - 2000	K20 - K30	Classic reliable grade with high impact resistance. Best suited for semi-finishing or roughing cast iron and non-ferrous alloys, as well as fabricating simple stamping dies and guiding components.
YG6X	Fine Grain	6%	91.0 - 92.0	1800 - 2000	K10	Fine-grained structure variant of YG6. Yields higher hardness and edge retention. Recommended for continuous high-speed finishing of non-alloyed steels and grey cast iron.
YG15	Medium	15%	86.5 - 87.5
