      3. Advantages: <\/h3>\n\n\n\n

      Cemented carbide has high hardness, strength, wear resistance and corrosion resistance. It is known as the “industrial teeth” and is used to manufacture cutting tools, knives, cobalt tools and wear-resistant parts. It is widely used in military industry, aerospace, mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields. With the development of downstream industries, the market demand for cemented carbide continues to increase. In addition, the future high-tech weapons and equipment manufacturing, the progress of cutting-edge science and technology, and the rapid development of nuclear energy will greatly increase the demand for cemented carbide products with high technology content and high quality stability. <\/p>\n\n\n\n

      4. FAQ(Frequently Asked Questions) of cemented carbide:<\/h3>\n\n\n\n

      (1) What are the core performance indicators for cemented carbide? How is its quality assessed?<\/h5>\n\n\n\n

      Answer: The core performance indicators and quality assessment criteria are as follows: The primary focus is on four key indicators\u2014hardness (HRA 82\u201393.6), density (11.0\u201315.0 g\/cm\u00b3, varying with composition), transverse rupture strength, and toughness. Additionally, metallographic parameters\u2014such as porosity and uncombined carbon content\u2014must be inspected. A product is deemed qualified if it is free of visual defects (such as delamination, cracks, or burrs) and complies with the requirements of the ISO 4489:2019 standard.<\/p>\n\n\n\n

      (2) In cemented carbide, how does the cobalt content affect product performance?<\/h5>\n\n\n\n

      Answer: Cobalt (Co) serves as the primary binder in cemented carbide; its content directly determines the balance between the product’s hardness and toughness: \u2460 Higher cobalt content (e.g., 8%\u201312%) results in superior toughness and greater impact resistance, though hardness and wear resistance may decrease slightly. This composition is suitable for applications prone to impact, such as rough machining and interrupted cutting. \u2461 Lower cobalt content (e.g., 3%\u20136%) yields higher hardness and wear resistance, but results in reduced toughness. This composition is suitable for applications with extremely high wear resistance requirements, such as finish machining and high-speed cutting. The specific cobalt content ratio can be adjusted based on the particular working conditions.<\/p>\n\n\n\n

      (3) What are the corrosion resistance and high-temperature resistance properties of cemented carbide? In which extreme environments is it suitable for use?<\/h5>\n\n\n\n

      Answer: \u2460 High-Temperature Resistance: Cemented carbide can retain its hardness at high temperatures ranging from 800\u00b0C to 1000\u00b0C\u2014far exceeding the capabilities of high-speed steel\u2014making it suitable for applications involving high-temperature cutting, metallurgy, and similar processes. \u2461 Corrosion Resistance: The corrosion resistance of cemented carbide depends on its binder and alloying elements; cobalt-based cemented carbides offer moderate corrosion resistance, whereas nickel-based cemented carbides offer superior resistance and are suitable for use in corrosive environments such as those found in the chemical and marine industries. \u2462 Note: Cemented carbide is not suitable for prolonged exposure to high-temperature, strongly oxidizing environments (e.g., temperatures exceeding 1000\u00b0C in the presence of oxygen), as this can lead to oxidative failure.<\/p>\n\n\n\n

      (4) What are the inspection standards for cemented carbide products? Which specific items are primarily tested?<\/h5>\n\n\n\n

      Answer: Currently, domestic standards adhere to ISO 4489:2019, Hardmetals\u2014Rules for inspection and testing. The primary testing categories encompass five areas: \u2460 Chemical composition (main metal content, total carbon content, oxygen content, etc.); \u2461 Physical and mechanical properties (density, hardness, transverse rupture strength; and, where necessary, coercivity, magnetic saturation, impact toughness, etc.); \u2462 Metallographic structure (porosity, free carbon, microstructure, etc.); \u2463 Dimensions (geometric dimensions, form and position tolerances, etc.); \u2464 Visual quality (absence of defects such as delamination, cracks, peeling, burrs, oxidation, etc.).<\/p>\n\n\n\n
