锻件比铸件能承受更高的剪切力和拉伸力。铸件的优点在于可以制造出比较复杂的外形，成本比较低；且内部组织均匀，不存在铸件气孔，夹杂等有害缺陷；从生产工艺流程区别铸造法兰和锻造法兰，如离心法兰就属于铸造法兰的一种。
Forgings can withstand higher shear and tensile forces than castings. The advantages of castings are that they can produce more complex shapes and lower costs; and the internal structure is uniform, and there are no harmful defects such as blowhole and inclusion; casting flange and forging flange can be distinguished from production process, such as centrifugal flange, which belongs to casting flange.
离心法兰属于精密铸造方法，该种铸造较普通砂型铸造组织要细很多，质量提高不少，不易出现组织疏松、气孔、沙眼等问题。
Centrifugal flange belongs to precision casting method. Compared with common sand casting, this casting method has much finer structure and much better quality. It is not easy to have loose structure, pore and trachoma.
