Cast iron is an iron-carbon alloy with a carbon content greater than 2.11% (generally 2.5-4.0%). And during its solidification process, the carbon element will be precipitated in the form of graphite.

This structure gives graphite many unique properties. Its texture is soft, the Mohs hardness is only 1-2, and there is a sense of smoothness. Graphite has good electrical and thermal conductivity, and its electrical conductivity is lower than that of general metal materials. But it is an excellent conductor in non-metallic materials. In addition, the chemical properties of graphite are stable. And it is not easy to chemically react with other substances at room temperature, and has good corrosion resistance.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Importance_of_graphite_in_cast_iron\"><\/span>Importance of graphite in cast iron<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Graphite plays a key role in cast iron. From the point of view of mechanical properties, the presence of graphite is similar to the formation of a large number of tiny &#8220;crack sources&#8221; in the metal matrix. This\u00a0will reduce the strength and toughness of cast iron. However, graphite also gives cast iron some special properties. For example, the lubrication effect of graphite makes cast iron have good anti-friction and wear resistance. It\u00a0is of great significance in the manufacture of parts such as plain bearings and machine tool guides. The thermal conductivity of graphite helps the cast iron to dissipate heat evenly during the heating process and improve its thermal stability. Moreover, the presence of graphite can also make the cast iron obtain good casting properties. Such as reducing the surface tension of liquid iron, improving its fluidity. This is conducive to the <a href=\"https:\/\/topsbest-precision.com\/die-casting-services\/\" target=\"_blank\" rel=\"noopener\">fundici\u00f3n<\/a> of complex shaped parts.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Different_types_of_graphite_in_cast_iron\"><\/span>Different types\u00a0of\u00a0graphite in cast iron<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Spheroidal_graphite_cast_iron_Nodular_graphite_cast_iron\"><\/span>Spheroidal graphite cast iron (Nodular graphite cast iron)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Nodular graphite cast iron and spheroidal graphite cast iron refer to the same material.

Spheroidizing agent reduces the surface tension of carbon in liquid iron and makes graphite grow spherically. The inoculant increased the number of nucleation of graphite, refined and homogenized the graphite balls. And solidified the iron liquid into spherical graphite at a suitable temperature.<\/p>\n<p>&nbsp;<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Properties_of_spheroidal_cast_iron\"><\/span>Properties of spheroidal cast iron<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Excellent mechanical properties, tensile strength of more than 400MPa-1000MPa, far beyond gray cast iron.

Although nodular cast iron needs more precise control of spheroidization and inoculation treatment, it has good fluidity and filling. It\u00a0can meet the production of complex castings.
