Compacted Graphite Iron. Compacted graphite iron is an emerging cylinder block material having a higher specific strength than conventional gray iron, and with improved fatigue strength and acoustic properties relative to aluminum, thereby allowing cast iron blocks of reduced thickness and mass to be constructed (Tholl 1996).

Sand Casting | Metal Casting Resources

Sand casting is a process that utilizes non-reusable sand molds to form metal castings.It is a common production method for metal components of all sizes, from a few ounces to several tons. Sand casting isn't only versatile in the size of its products – it can also create exceptionally complex or detailed castings, and can be used to cast nearly any metal alloy.

Workpiece materials - Coromant

Alloying elements. C influences hardness (higher content increases abrasive wear). Low carbon content, < 0.2%, increases adhesive wear, which will lead to built-up edge and bad chip breaking. Cr, Mo, W, V, Ti, Nb (carbide formers) increase abrasive wear.. O has a large influence on machinability; it forms non-metallic, oxidic and abrasive inclusions.. Al, Ti, V, Nb are used for the fine ...

Cast Iron | Machine Design

Steels and cast irons are both primarily iron with carbon as the main alloying element. Steels contain less than 2 and usually less than 1% carbon; all cast irons contain more than 2% carbon.

Grey Iron Casting | INVESTMENT CASTING

Processes of Grey Iron Castings. Commonly used process for grey iron castings in the market is produced by sand casting. The processes using sand as the mold media have a somewhat similar effect on the rate of solidification of the casting, while the permanent mold process has a very marked effect on structure and properties.

Quenching - Wikipedia

In materials science, quenching is the rapid cooling of a workpiece in water, oil or air to obtain certain material properties.A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring. It does this by reducing the window of time during which these undesired reactions are both thermodynamically favorable, and kinetically ...

Cast Iron vs Cast Steel | Metal Casting Blog

Pig iron is created after iron ore is mixed with carbon in a series of furnaces. This material can be changed further into cast iron, steel or wrought iron depending on the selected manufacturing process. Cast iron is an iron carbon mixture that is generally used to pour sand castings, as opposed to making billets or bar stock.
