Nanjing Xinshuo Mechanical Equipment Co., Ltd.

produces gray, ductile and compacted graphite iron castings. The difference in these types of iron is the characteristics of the graphite used in the material. 
Gray Iron
Benefits of gray iron are: 
Excellent castability
Good machinability
Good wear resistance
High damping capacity which means it limits vibration in a finished casting
High thermal conductivity and is able to wick away heat
Excellent compressive strength
Good tensile strength
 
We produce several different grades of gray iron castings at our foundries:
Damped G1800…145-201 HBW,
FC150 HC…149-229 HBW,
FC150 B…170-235 HBW,
G3000… 187-241 HBW,
G3500 Base…187-255 HBW,
G3500 Alloyed…207-255 HBW,
G4000 Base …197-269 HBW,
G4000 Alloyed …217-269 HBW,
 
Ductile Iron
In Ductile iron the graphite is like a pillow and acts as "crack-arresters" to give ductility and toughness superior to all other cast irons. Benefits of ductile iron are:
Excellent tensile strength
Increased ductility which ensures finished materials will bend before breaking
Excellent impact properties
Good machinability
High modulus of elasticity which measures the degree of "stiffness" in the material
We produce several different grades of ductile iron castings at our foundries

Products manufactured:  Hydraulic housings, flywheels, weights, covers, brackets, turbo bearing housings, clutch housings, pulleys, brake rotors, Ductile Iron pipe
Compacted graphite iron
Compacted graphite iron has characteristics midway between ductile and gray iron and combines many of the properties of both.
 
Abrasion Resistant Cast Iron (ASTM A532):
Wear and Abrasion Resistant Cast Irons (White Irons)
Abrasion Resistant cast irons are widely used in abrasive wear applications involved in the crushing, grinding, milling and handling of abrasive materials such as minerals and ores, both dry and as slurries. Three types of irons are commonly used:
SpecificationsIron type: Cast iron, Gray iron, Ductile Iron, Compacted graphite iron, Abrasion Resistant Cast Iron
Casting size:    1 kg - 3000 kg
Melt capacity: 5 tons per hour
Production process:Resin coated sand casting, Sand casting, Centrifugal casting, Lost Foam Casting, ( LFC, EPC ), Gravity casting, CNC machining, Heat treatment.
