Gray Iron

Join Austin Zimmerman at Houston Metal Sawing as we address the challenges of sawing gray iron. This video highlights our process of making over 8,000 precise cuts on gray iron, known for its abrasive nature, similar to 4130 or 4140 chromoly. See how we utilize s Sawblade.com’s tools, notably the Q701 Superior M71 Bi-Metal Blade, to efficiently manage this demanding task.

Gray iron, often referred to as “cast iron,” has a distinct flake graphite structure. This unique composition grants it self-lubricating attributes, enhancing machinability. Its inherent damping capabilities suit it for machinery bases and automotive applications. While it may exhibit brittleness affecting its tensile strength, gray iron remains notable for its thermal conductivity, wear resistance, and superior compressive strength, making it a preferred material for components like vehicle brake discs.
