Grey Iron Casting
Professional gray cast iron suppliers Grey Cast Iron that contains flake-like graphite, and its name varies depending on the base structure. The name “ gray ” comes from the fact that the fracture surface is gray, or mouse-colored. grey cast iron foundry , with flake graphite as its core feature, has excellent shock absorption, wear resistance, and processing performance, and is widely used in pressure bearing components such as automotive cylinder blocks and machine tool bases. Its eutectic structure provides high compressive strength (200-400MPa) and thermal conductivity, but low toughness. The casting process optimizes the graphite morphology by controlling the silicon to carbon ratio, and achieves mass production of complex thin-walled parts through sand/metal casting. The cost is 40% -60% lower than forging, but the cooling rate needs to be controlled to avoid white defects. Suitable for static high load scenarios, replacing some steel components to reduce system ener...
