Carbide alloy rod
Our company provides customers with a variety of high quality carbide round bars: round bar blanks, non-porous blanks and finished round bars. At the same time, our company can also provide customers with a bar with one hole, two or more holes. We can provide round rods with a length range of 2-330mm and a diameter of ф0.4-ф330mm.
| Grade | ISO code | Cobalt % | WC % | Grain size um | Density G/CM3 | Vickers hardness Kg/mm2 | Rockwell hardness ISO 3738 | Bending strength N/mm2 | Remarks |
| YL 10.2 | K20-K30 | 10 | 90 | 0.6 | 14.5 | 1600 | 91.8 | 4000 | Fine-grained carbide with a grain size of 0.6um. The solid carbide tool made from it is very versatile. It is the most common type of K-grade cemented carbide, as long as it is used to process ordinary steel, cast iron,stainless steel,heat-resistant steel, nickel-based and titanium alloys.They are usually made into general-purpose tool materials such as twist drills, vertical boring tools, taps, and gun drills. |
| YG 12 | K40-K50 | 12 | 88 | 0.5 | 14.1 | 1680 | 92.5 | 4000 | The cemented carbide material with a grain size of 0.5 μm and a cobalt content of 12% guarantees its high toughness and high hardness. It can be used for hole machining and threading, and is also particularly suitable for boring titanium alloys, heat resistant alloys, grey cast iron, stainless steel, hardened steel (hardness <60HRC), steel glass and some composite materials. |
| YG 6 | K05-K10 | 6 | 94 | 0.5 | 14.8 | 1950 | 94.3 | 3800 | Tungsten carbide made of ultra-fine tungsten carbide powder with a sintered grain size of 0.5μm is suitable for processing glass fiber, wood, plastic, aluminum-magnesium alloy, etc. It is recommended for making all kinds of hard alloy tools and PCB micro drills and micro-miller cutter. |
| YG 6X | K05 | 6 | 94 | 0.8 | 14.9 | 1750 | 91.5 | 3400 | This is a grain size of 0.8 μm. Carbide material with 6% cobalt content, suitable for high-speed finishing of small and medium cut surface of chilled cast iron, ductile iron, gray cast iron and heat resistant alloy. It is the first choice for processing reamer, alloy, red brass, bronze and plastic. |
| YG 15 | K30-K40 | 15 | 85 | 1.2 | 14 | 1110 | 87.6 | 4000 | The grain size was 1.2 μm. Cemented carbide material with a cobalt content of 15% is suitable for making integral molds and tools for stamping, such as punching pins, punches, and mold parts. |
