Meehanite Specifications Properties Application Examples
GM-GA Among all G-type gray cast iron, it has the highest tensile strength, average fine pearlite structure, can be surface harden treatment. Suitable for medium and large thick wall casting. Industrial machinery and auto/locomotive cylinders, gears, bearings; machine tool base, post, saddle; compressors and diesel engine cylinder and liner; various types of rollers, valve, pressure casting; high mechanical performance required parts castings.
GC-GB The optimum high toughness G-type gray cast iron, tensile strength, excellent lubricity, and high pressure resistance, surface can be hardened, and suitable for high mechanical performance required castings.
GD-DE Only with normal strength, well cutting resistance, high anti-shock system, can absorb noise and vibration. Suitable for general industrial machinery parts pieces. General industrial machinery of bracket, bed seat, flywheel, gearbox, shell cover; cam with auto/locomotives, brake drums, clutch plates, and so on.

Meehanite Metal Properties Application Examples
SFF-SF Form it by dissolving high purity raw materials and process control. It comes with excellent low-temperature impact resistance and most suitable casting choice for frigid areas. Frigid zone used freezers, compressors, pumps, valve, and other components, high pressure resisted dense components, mechanical parts, pressure wall and so on used under low temperature.
SPF-SP Pearlite ductile cast iron comes with high strength, toughness and moderate elongation, good processability, a bit of wear resistance, can be surface hardened. Most suitable for general industrial machinery components applications Hydraulic parts, high pressure pump, hydraulic cylinders, gears, excavator parts, diesel vehicle piston, crank shaft, clutch housings, cylinder block, both static/ dynamic loads parts.
SH Very fine pearlite ductile iron, or by normalization process, or quenched and tempered Martensite, it has high strength and hardness, but poor ductility and toughness. Aluminum extrusion machine crosshead, steel pumping pipe, rolling machine wheel, crushing machine wear parts, pulverizers wear plates and blades.
