Gray iron castings

Gray cast iron is a relatively inexpensive cast iron material with good casting properties and machining performance. It is widely used in various mechanical parts such as frames, boxes, and shells. The graphite inside gray cast iron is distributed in flakes. Graphite is prone to stress concentration, so gray cast iron has low strength, plasticity and toughness, but has excellent shock absorption, low notch sensitivity and wear resistance.
