Di cosa \u00e8 fatto il carburo cementato? Il carburo cementato \u00e8 una lega ottenuta dalla metallurgia delle polveri con una o pi\u00f9 polveri di carburo refrattario (<a href=\"https:\/\/www.wolframcarbide.com\/it\/\">carburo di tungsteno<\/a>carburo di titanio, ecc.) come componente principale e polveri metalliche (cobalto, nichel, ecc.) come leganti. Viene utilizzato principalmente per la produzione di utensili da taglio ad alta velocit\u00e0 e di utensili da taglio per materiali duri e tenaci, nonch\u00e9 per la produzione di utensili da taglio per materiali duri e tenaci.<a href=\"https:\/\/www.wolframcarbide.com\/it\/prodotto\/wolfram-carbide-edm-blocks-for-stamping-mold-and-stamping-dies\/\"> stampi per la lavorazione a freddo<\/a>, strumenti di misura e <a href=\"https:\/\/www.wolframcarbide.com\/it\/categoria-di-prodotto\/bottoni-e-inserti-in-carburo-di-tungsteno-per-lindustria-mineraria-e-ledilizia\/\">parti ad alta resistenza all'usura<\/a> che non risentono di urti e vibrazioni.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><a href=\"https:\/\/www.wolframcarbide.com\/it\/prodotti\/\"><img decoding=\"async\" src=\"https:\/\/www.wolframcarbide.com\/wp-content\/uploads\/2024\/12\/Cemented-carbide-products-1.jpg\" alt=\"Che cos&#039;\u00e8 il carburo cementato\" title=\"\"><\/a><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">1. Caratteristiche del carburo cementato:<\/h3>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;\u2474 Elevata durezza, resistenza all'usura e durezza rossa La durezza del carburo cementato pu\u00f2 raggiungere 86~93HRA a temperatura ambiente, equivalente a 69~81HRC. Pu\u00f2 mantenere un'elevata durezza a 900~1000\u2103 e ha un'eccellente resistenza all'usura. Rispetto all'acciaio per utensili ad alta velocit\u00e0, la velocit\u00e0 di taglio pu\u00f2 essere 4~7 volte superiore, la durata \u00e8 5~80 volte pi\u00f9 lunga e si possono tagliare materiali duri fino a 50HRC.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2475 Elevata resistenza e <a href=\"https:\/\/en.wikipedia.org\/wiki\/Elastic_modulus\" rel=\"nofollow noopener\" target=\"_blank\">modulo elastico<\/a> La resistenza alla compressione del carburo cementato raggiunge i 6000MPa e il modulo elastico \u00e8 di (4~7)\u00d7105MPa, entrambi superiori all'acciaio rapido. Ma la sua resistenza alla flessione \u00e8 bassa, in genere 1000 ~ 3000MPa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Buona resistenza alla corrosione e all'ossidazione In generale, resiste molto bene alla corrosione atmosferica, agli acidi, agli alcali e ad altre forme di corrosione e non \u00e8 facile da ossidare.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2477 Piccolo coefficiente di espansione lineare Durante la lavorazione, la forma e le dimensioni sono stabili.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2478 I prodotti formati non vengono pi\u00f9 lavorati o riaffilati A causa dell'elevata durezza e fragilit\u00e0 del carburo cementato, la formatura e la sinterizzazione con la metallurgia delle polveri non vengono pi\u00f9 tagliate o riaffilate. Quando \u00e8 necessaria una rilavorazione, \u00e8 possibile utilizzare solo la lavorazione elettrica, come la scintilla elettrica, il taglio a filo, la rettifica elettrolitica o la rettifica con mola speciale. I prodotti di determinate specifiche, solitamente in carburo cementato, vengono brasati, incollati o bloccati meccanicamente sul corpo dell'utensile o dello stampo per l'uso.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. I carburi cementati comunemente utilizzati si dividono in tre categorie in base alla composizione e alle caratteristiche di prestazione:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.wolframcarbide.com\/it\/prodotti\/\"> Tungsten-cobalt<\/a>, tungsten-titanium-cobalt, and tungsten-titanium-tantalum (niobium). The most widely used in production are tungsten-cobalt and tungsten-titanium-cobalt cemented carbides.<\/p>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">\u2474 Carburo di tungsteno-cobalto cementato I componenti principali sono il carburo di tungsteno (WC) e il cobalto. Il grado \u00e8 rappresentato dal codice YG (le iniziali cinesi pinyin di \"duro\" e \"cobalto\"), seguito dalla percentuale di cobalto contenuta. Ad esempio, YG6 rappresenta un carburo cementato di tungsteno-cobalto con un contenuto di cobalto pari a 6%, e il contenuto di carburo di tungsteno WC = 1-WCo = 94%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2475 Carburo cementato di tungsteno-titanio-cobalto I componenti principali sono il carburo di tungsteno (WC), il carburo di titanio (TiC) e il cobalto. Il grado \u00e8 rappresentato dal codice YT (le iniziali cinesi pinyin di \"duro\" e \"titanio\"), seguito dalla percentuale di carburo di titanio contenuta. Ad esempio, YT15 rappresenta un carburo cementato di tungsteno-titanio-cobalto con un contenuto di carburo di titanio pari a WTiC = 15%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Carburo cementato di tungsteno-titanio-tantalio (niobio) Questo tipo di carburo cementato \u00e8 chiamato anche carburo cementato generale o carburo cementato universale. I suoi componenti principali sono il carburo di tungsteno (WC), il carburo di titanio (TiC), il carburo di tantalio (TaC) o il carburo di niobio (NbC) e il cobalto. Il marchio \u00e8 rappresentato dal codice YW (il primo pinyin cinese dei due caratteri \"hard\" e \"wan\") seguito da un numero ordinale.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Advantages: <\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cemented carbide has high hardness, strength, wear resistance and corrosion resistance. It is known as the &#8220;industrial teeth&#8221; 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.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. FAQ(Frequently Asked Questions) of cemented carbide:<\/h3>\n\n\n\n<h5 class=\"wp-block-heading\">(1) What are the core performance indicators for cemented carbide? How is its quality assessed?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">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<h5 class=\"wp-block-heading\">(2) In cemented carbide, how does the cobalt content affect product performance?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Answer: Cobalt (Co) serves as the primary binder in cemented carbide; its content directly determines the balance between the product&#8217;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<h5 class=\"wp-block-heading\">(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<p class=\"wp-block-paragraph\">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<h5 class=\"wp-block-heading\">(4) What are the inspection standards for cemented carbide products? Which specific items are primarily tested?<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">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<p class=\"wp-block-paragraph\">La nostra azienda \u00e8 tra le prime dieci in Cina&nbsp;<a href=\"https:\/\/www.wolframcarbide.com\/it\/prodotti\/\">produttori di carburo cementato<\/a>.
