Ferritic cast iron material having a laminated graphite structure comprises carbon, silicon, aluminum, bismuth, phosphorus, copper, manganese, and tin, where cylindrical head, brake disk and cylinder liner are formed from the iron material

摘要

The ferritic cast iron material having a laminated graphite structure comprises 3.9-4.2 wt.% of carbon, 0.3-0.9 wt.% of silicon, 2-5.9 wt.% of aluminum, 0.005-0.03 wt.% of bismuth, 0.04 wt.% of phosphorus, 0.3 wt.% of copper, 0.4 wt.% of manganese, 0.1 wt.% of tin and the balance of iron. A cylindrical head, a brake disk and a cylinder liner are formed from the cast iron material.
