Product Details, Specifications, and Technical Information

Cast Iron Rectangle Bar G2 Dura-bar offers high wear resistance, strength, durability, vibration dampening, fatigue resistance, with excellent consistency and finish. G2, a non-ductile iron, is comparably strong to 1040 steel in the "as-rolled" condition, and is manufactured through the Continuous Cast process. This removes porosity and makes it superior to other cast irons. It is typically used in the automotive and power industries for gears, rotors, pistons, valves, rollers, bushings, chucks, flywheels, pile drivers, rams pulleys, housings, and motorcycle disc brakes.
