class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Compacted graphite iron (cgi) is a kind of cast iron material with unique graphite form. Its graphite is neither flaky like ordinary gray cast iron, nor spherical like ductile cast iron, but shows a tight, curled form in between. This special graphite form gives cast iron a series of excellent properties.<\/p>\n<p>In the cast iron material system, the compacted graphite iron grades can be divided according to the different graphite forms. Different grades of it\u00a0have different properties. And their unique graphite morphology determines their performance in strength and toughness. For example, higher grades of compacted graphite iron is\u00a0be\u00a0suitable for industrial areas with higher performance requirements.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Basic_principle_of_compacted_graphite_iron\"><\/span>Basic principle of compacted graphite iron<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Graphite_form\"><\/span>Graphite form<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<h4><span class=\"ez-toc-section\" id=\"Graphite_form_of_compacted_graphite_iron\"><\/span>Graphite form of compacted graphite iron<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>The graphite morphology of it\u00a0presents a wormlike shape.

Thus effectively improving the mechanical properties of cast iron.<\/p>\n<p>&nbsp;<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Formation_Mechanism\"><\/span>Formation Mechanism<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>In the casting process, by adding specific alloying elements, such as magnesium, calcium, etc., to promote graphite crystallization to form wormlike. These elements inhibit the growth of graphite, allowing it to form a relatively stable structure. At the same time, in the casting process, the cooling rate and solidification conditions also play an important role in the formation of graphite form.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Alloy_composition\"><\/span>Alloy composition<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Compacted graphite iron is mainly composed of iron, carbon, silicon, manganese and other elements.
