Cast iron possesses the highest strength, hardness, resistance to
wear and heat treating response for an unalloyed gray iron.
Machinability, noise and vibration damping is Excellent to Very
Good. Continuous casting virtually eliminates rejections due to
porosity and centerline shrinkage.
Typical Applications
●Hydraulic cylinders
●Manifolds
●Bushings
●Bearings
Our foundry cuts material to the specifications provided by its
customers through one of the many machines on hand. Our precision
plate saws, bar saws, shears, and water jets have the ability to
deliver your exact needs.
