OVERVIEW
HJ additives for diamond tools Type I is used an additive for metal bond of diamond tools especially for medium and premium diamond blades. Recommended adding 6%-15% amount of products while maintaining the same original formula. The function is to enhance the bending strength, Rockwell hardness of matrix and self-sharpening performance of diamond tools. Type I can not only work as additives for diamond tools, but also has modifying effects on other elements to obtain using effects.
Application: Suitable for diamond products manufacturers, pre-alloyed powder plants, premixed powder factories, powder metallurgy plants, abrasive plants, grinding wheel manufacturers, refractory electrodes, ceramic products.
FEATURES
1. Elements: Main composition Fe, Co, Ni, P.
Huijin Corporation has been engaging in the research of phosphorus. Therefore, phosphorus exists in all the series of HJ additives for diamond tools, which drives the flow of hard metal, improves the fluidity of the tools and compactness of the products.
Otherwise, aiming at the characteristics of HJ additives for diamond tools Type I, the cobalt powder, nickel powder are added, by water atomization process, the alloying degree, sinterability and repeatability are especially good.
2. Performance: sharp and wear-resisting.
In 2008, Huijin technical department specially cooperated with Zhengzhou University and professors of Beijing, which solved the technical problem that sharpness and wear-resistance are conflict. Experiments show that by adding HJ additives for diamond tools Type I, only 6%-15% amount of products, it can improve the sharpness by 16%-30%, the service life by 10%-28%.
3. Apparence: Irregular shape of the powder particle, particle size can reach 300 mesh to 1200 mesh.
The geometric properties of particles include shape and size. In order to ensure product properties, the shape and size should be controlled in industry. The products are easily shaped due to the irregular shape of HJ additives for diamond tools Type I.
Otherwise, Huijin Corporation ensures the uniformity and stability of powder particle size distribution by adopting laser particle size analyzer.
4. Quality: Low oxygen content, hard to be oxidized.
Huijin Corporation is located in the north of China, the powder is not easy to be oxidized and the natural environment is better than the south because of the dry air and low humidity of below 30%.
5. Comprehensive features: High overall performance.
HJ additives for diamond tools Type I can effectively improve the overall performance of diamond tools. By adding it, the alloying extent of diamond tools matrix can be increased, the uniformity of sintered body tissue is improved, also, it enhances the diamond retention, shortens the sintering time and reduces the losses of low melting point metal. The density and self-sharpening performance of diamond tools can be improved. The life of diamond tools has been extended while the sharpness has been maintained the same level, which made the overall performance of diamond tools improved.
Summary: By testing the overall performance, it shows that HJ additives for diamond tools Type I is suitable for medium and premium diamond tools to improve the competitive advantage due to its excellent auxiliary performance.
