GRAY IRON CASTINGS
WHY GRAY IRON CASTINGS?
Gray iron is an alloy composed of 95% iron, with an addition of 2.1% – 4% carbon and 1% – 3% silicon. The name of the material is derived both from its basic composition and from the grayish hue that fractured surfaces of the metal typically possess. It can be spelled either as gray or grey, even though American usage tends to be gray.
Gray iron castings can be produced through several different metallurgical and core processes, including sand casting and die casting. Selecting your preferred casting process depends largely upon the size of the production run and the preferred characteristics of the final part.
Common applications for the use of gray iron castings in the OEM (original equipment manufacturing), automotive and aerospace industries include valves, forges, compressors, pumps, and more.
These components exhibit the following properties:
- excellent machinability
- great wear resistance
- excellent dampening capacity
- excellent castability
- resistance to cracking
- low solidification shrinkage
- significant cast-in details
- high-temperature properties
