gray iron castings

Gray iron castings

Gray cast irons are the most used of the general purpose engineering irons. They are relatively inexpensive and easy to produce. They are readily machined and the machined surfaces are resistant to sliding wear. They have high thermal conductivity, low modulus of elasticity and an ability to withstand thermal shock. This makes the material suitable for castings subjected to local or repeated stressing.
