球墨水鑄鐵零件
Ductile iron casting is a kind of high strength cast iron material developed in the 1950s. Its comprehensive performance is close to steel. It is based on its excellent performance, it has been successfully used for casting some parts with complex force, high strength, toughness and wear resistance. Ductile iron has rapidly developed into a widely used cast iron material second only to grey cast鐵.所謂的“鋼代替鋼”，主要指的是延性鐵.延性鐵是通過球形和妊娠處理的球形石墨，從而有效地提高了鑄鐵的機械性能，尤其改善了鑄鐵的機械性能，尤其改善了比較高的可塑性和韌性，以便獲得更高的強度，以便獲得比碳鋼的強度更高的強度。
