Melting & Pouring

We have the capability to produce castings from ounces to 25 lbs. in medium to high volumes with finishing capabilities in machining & Assembly.

At its heart, Frazer & Jones is a DISAmatic, high pressure, green sand, ferrous cast iron foundry specializing in almost all industrial grades of Ductile Iron, Austempered Ductile Iron (ADI), High Silicon, Molybdenum Alloyed Ductile Iron (SiMo).

Also available are most commercial grades of both Malleable & Gray Irons.

Cast Materials

Ferritic Ductile Iron
Graphite spheroids in a matrix of ferrite provides an iron with good ductility and impact resistance and with a tensile and yield strength equivalent to a low carbon steel. Ferritic Ductile Iron can be produced "as-cast" but may be given an annealing heat treatment to assure maximum ductility and low temperature toughness.

Ferritic - Pearlitic Ductile Iron
These are the most common grade of Ductile Iron and are normally produced in the "as cast" condition. The graphite spheroids are in a matrix containing both ferrite and pearlite. Properties are intermediate between ferritic and pearlitic grades, with good machinability and low production costs.

Pearlitic Ductile Iron
Graphite spheroids in a matrix of pearlite result in an iron with high strength, good wear resistance, and moderate ductility and impact resistance. Machinability is also superior to steels of comparable physical properties.

The preceding three types of Ductile Iron are the most common and are usually used in the as-cast condition, but Ductile Iron can be also be alloyed and/or heat treated to provide the following grades for a wide variety of additional applications.

Martensitic Ductile Iron
Using sufficient alloy additions to prevent pearlite formation, and a quench-and-temper heat treatment produces this type of Ductile Iron. The resultant tempered martensite matrix develops very high strength and wear resistance but with lower levels of ductility and toughness.

Austempered Ductile Iron (ADI)
ADI, the most recent addition to the Ductile Iron family, is a sub-group of Ductile Irons produced by giving conventional Ductile Iron a special austempering heat treatment. Nearly twice as strong as pearlitic Ductile Iron, ADI still retains high elongation and toughness. This combination provides a material with superior wear resistance and fatigue strength.

Silicon- Molybdenum (SiMo) Ductile Irons
Alloy Ductile Irons containing 4-6% silicon, either alone or combined with up to 2 % molybdenum, were developed to meet the increasing demands for high strength Ductile Irons capable of operating at high temperatures in applications such as exhaust manifolds or turbocharger casings. The primary properties required for such applications are oxidation resistance, structural stability, strength, and resistance to thermal cycling.

Ferritic Malleable Iron
Temper Carbon in the form of irregularly shaped graphite nodules instead of flakes as in gray iron or spheroids as in ductile iron. Malleable iron is produced by first casting as ‘white iron’ and then heat treated (annealing) resulting in developed engineering properties. Malleable, like Ductile, possesses considerable ductility and toughness because of its combination of nodular graphite and low-carbon metallic matrix. Preferred for applications which must retain good impact.

Pearlitic Malleable Iron
Pearlitic Malleable iron is designed to have combined carbon in the matrix resulting in higher strength & hardness via alloying or specially designed heat treat cycles.

Martensitic Malleable Iron
Martensitic Malleable Iron is produced by quenching and tempering.

Gray Iron
Intended for General Engineering applications; classified on the basis of tensile strength providing good stiffness, damping capacity and thermal conductivity. Gray iron is very economical and possesses good machinability.
