Hard metal YG11 for dies and drilling tools
Hard metal YG11 is a type of die steel, specifically a tungsten carbide type of hard metal. The following is a detailed introduction to hard metal YG11:
1.Basic characteristics Chemical composition:
YG11 is mainly composed of wolfram carbide (WC) and cobalt (Co), of which the content of WC is about 89% and the content of Co is about 11%. This chemical composition makes YG11 have excellent hardness and wear resistance.
The following are the specific properties of hard metal YG11:
| WC | Co | Grain size (μm) | Hardness (HRA) | Density (g/cm³) | TRS (N/mm²) | coefficient of thermal expansion | Elastic Modulus（GPa） |
| 89% | 11% | 1.2-1.6 | 86.5 | 14.40 | 2450 | 6.5X10^-6 /℃ | 410 |
2. Performance advantages consistent hardness inside and outside:
YG11 hardmetal does not undergo heat treatment, and its hardness inside and outside is uniform, which makes it easier to achieve the required shape and dimensional accuracy during the manufacturing process. The hardness of YG11 is very high, usually greater than or equal to 86.5HRA. This high hardness allows YG11 to maintain the stability of its shape and size when subjected to high pressure. Excellent wear resistance: Because YG11 contains a high proportion of tungsten carbide, it has excellent wear resistance. This wear resistance allows YG11 to maintain its performance stability during long-term use. High strength: YG11 has a moderate cobalt content, which gives it sufficient strength and toughness to withstand greater impact and vibration.
3. Main uses Making stamping dies:
YG11 is very suitable for making stamping dies, especially for stamping silicon steel sheets, Q195, SPCC and other materials. Its high hardness and wear resistance make the mold less likely to wear during use, thereby extending the service life of the mold. Making wear-resistant parts: YG11 can also be used to make parts that require good wear resistance, such as cutting tools, hard metal teeth and picks of mining tools, drilling tools, etc.
4. Production process:
The production process of YG11 hard metal usually includes batching, mixing, crushing, drying, screening, adding molding agent, re-drying, screening to obtain a mixture, mixed granulation, pressing, isostatic sintering, and inspection of the blank after sintering. These steps ensure the quality and stability of YG11 hard metal.
In summary, YG11 is a metal-ceramic composite material with high hardness and strong wear resistance, which is widely used in metal processing, mold manufacturing, mining drilling tools and other fields. Its parameter data include density, hardness, flexural strength, longitudinal elastic modulus and carbon content, etc., with excellent mechanical properties. With its excellent performance, YG11C provides solid support for industrial production in various fields.
