Φ38x8.4mm Carbide Rod Blanks | Tungsten Round Discs Manufacturer
Product Overview
These Φ38x8.4mm tungsten carbide rod blanks (round discs) are sintered using 100% virgin raw materials. Engineered with exceptional hardness and high bending strength, they serve as ideal substrates for manufacturing custom cutting tools, precision mold components, and industrial wear-resistant liners.
Features
100% Virgin Material: Ensures stable mechanical performance, avoiding premature micro-chipping or cracking.
High Density & Hardness: Delivers excellent heat and corrosion resistance during high-speed or harsh operations.
Flawless Internal Structure: Undergoes HIP (Hot Isostatic Pressing) sintering to eliminate inner porosity, drastically boosting tool life.
Applications
Tool Manufacturing: Ideal for grinding down into bespoke profile milling cutters, end mills, or rotary burrs.
Stamping & Dies: Widely utilized as punch tips, die cores, or wear rings in automotive and metal forming industries.
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 |
