What Are the Benefits of Gray Cast Iron for Machined Parts?
Gray iron offers many valuable properties for heavy machinery parts:
- Vibration-dampening structure
- High thermal conductivity
- Outstanding thermal cycling
- Good corrosion resistance
- High compressive strength
- Low shrinkage during the casting process
This metal has a minimum tensile strength of 20,000 psi (60,000 psi max) and a Brinell hardness rating of 100 to 300.
What Is Gray Iron's Machineability Rating?
The graphite structure of gray cast iron makes it relatively easy to machine. Depending on the metal’s chemical makeup, it can vary from 90% to 170% machinability rating, better than stainless steel.
Why Is Gray Iron Machining Necessary?
The malleability of gray iron makes it easy to cast in a variety of shapes, but gray iron casting leaves the metal with a rough outline. For tight tolerances, exact specifications, and precise or complex assemblies, machining is a must.
