| Advantages to Gray Iron |
Gray iron is a very versatile foundry metal that is suitable for producing a variety of castings for pump, valve, compressor, motor, rail, mining, and automobile.
Classes: CL30 / CL35 / CL40 tensile and chilled iron |
| » |
Resistance to cracking |
| » |
High temperature properties |
| » |
Inexpensive to produce and to finish |
| » |
