Gray iron has graphite flakes, making it brittle but good at dampening vibration. Ductile iron is treated with magnesium to form spherical (nodular) graphite, which gives it much higher tensile strength, impact resistance, and ductility (the ability to bend without breaking).<\/p><\/div>\n                <\/div>\n                <div class=\"faq-item\">\n                    <div class=\"faq-question\">Can Ductile Iron replace Carbon Steel Castings? <span class=\"faq-icon\">+<\/span><\/div>\n                    <div class=\"faq-answer\"><p>In many cases, yes. Ductile iron offers a yield strength comparable to many cast carbon steels but is easier to cast and machine, resulting in a lower overall part cost. It is an excellent upgrade for parts that are too stressed for gray iron but don&#8217;t strictly require the weldability of carbon steel.<\/p><\/div>\n                <\/div>\n                <div class=\"faq-item\">\n                    <div class=\"faq-question\">What is the maximum weight for ductile iron parts you can cast? <span class=\"faq-icon\">+<\/span><\/div>\n                    <div class=\"faq-answer\"><p>Our die casting foundry is equipped to handle custom ductile iron components ranging from 50 lbs up to 5,000 lbs (2.5 tons) per single piece, making us ideal for heavy machinery components.<\/p><\/div>\n                <\/div>\n                <div class=\"faq-item\">\n                    <div class=\"faq-question\">How is the machinability of Ductile Iron? <span class=\"faq-icon\">+<\/span><\/div>\n                    <div class=\"faq-answer\"><p>Ductile iron has excellent machinability, generally superior to carbon steel of equivalent hardness.
