According to the experts, tungsten carbide scrapers have been used for many years, but the geometries of thin scrapers made their use more difficult. While tungsten carbide is much more wear-resistant, it is also more susceptible to breakage and thus the older grades of material would not work for these special scrapers. The experts finally found the correct carbide grade for scrapers. Now, the new tungsten carbide grade has high hardness to meet the requirements of wear resistance, prolong the service life of the scrapers, reduce the replacement rate, and improve production efficiency. And tungsten carbide has excellent toughness so that the scraper is not prone to crack. Also, it has good chemical stability, impact resistance, bending resistance and other excellent characteristics.
