Cast Iron Types

Compacted graphite iron applications Compacted graphite iron is beginning to make its presence known in commercial applications. The combination of the properties of gray iron and white iron create a high strength and high thermal conductivity product—suitable for diesel engine blocks and frames, cylinder liners, brake discs for trains, exhaust manifolds, and gear plates in high pressure pumps.

An Experimental Investigation of Machinability of Graphitic

Abstract In this study the machinability of different grades of cast iron has been studied in terms of cutting temperatures, cutting forces, tool life, deformed chip thickness and contact length in different continuous machining operations. The tests performed were: external turning, boring and face turning. Pearlitic Flake Graphite Iron (FGI), Compacted Graphite Iron (CGI) and Spheroidal

How to machine compacted graphite iron

Although graphite accounts for less than 4% by weight of cast iron, the shape of these particles determines physical and mechani-cal properties. In compacted graphite iron (CGI), the graphite appears as vermicular, or worm-like, particles and, three-dimensional

Iron Castings

Compacted graphite iron is challenging to make with uniformity, Waupaca Foundry closely monitors the production process. This type of iron provides many advantages: The internal porosity solidifies in a manner similar to gray iron with the strength of ductile iron and allows complicated castings.

Compacted graphite iron

Compacted graphite iron (CGI), also known as vermicular graphite iron (GJV, VG, JV or GGV from the German: Gusseisen mit Vermiculargraphit) especially in non-English speaking countries, is a metal which is gaining popularity in applications that require either greater strength, or lower weight than cast iron

Casting Process Simulation of Compacted Graphite Iron (03

Compacted Graphite Iron (CGI) has been known since the nineties as a high-strength casting material (Figure 1). However, applications of this material were limited due to uncertainties with regard to process control and machinability. Presently, the decision of

High speed turning of compacted graphite iron using

Compacted graphite iron (CGI) is a material which emerged as a candidate material to replace cast iron (CI) in the automotive industry for engine block castings. Its thermal and mechanical properties allow the CGI-based engines to operate at higher cylinder pressures and temperatures than CI-based engines, allowing for lower fuel emissions and increased fuel economy. However, these same

Compacted Graphite Iron for Diesel Engine Cylinder Blocks

diesel engines, compacted graphite iron, cylinder blocks 1. Introduction: In a recent paper discussing CGI uses for engine cylinder blocks and heads, S. Dawson (2001) stated that "the Iron Age is just beginning" and we have taken this statement for the

Compacted Graphite Iron: A Viable Alternative

Compacted Graphite Iron has been routinely produced in components of relatively simple geometry for more than 25 years, particularly those that can tolerate higher nodularities. However, it is only in the last 2-3 years that process control technology has evolved to

Machined Sand Casting manufacturer supplier

Compacted Graphite Iron has graphite particles which are randomly oriented and elongated similar to gray iron, but they are thicker, shorter and have shorter edges. The interconnected compacted graphite provides slightly higher thermal conductivity and more damping capacity.

The New CVD Coated Grade for Cast Iron Turning

are rising issues in machining interrupted and unstable cast surface, challenging us to seamlessly endeavor for improvements in machining stability. With the introduction of new materials like compacted graphite iron (CGI) and austempered ductile iron (ADI) in

Machinability of Compacted Graphite Iron (CGI), a

Compacted Graphite Iron (CGI) has an important role in manufacturing of new generation engines. Better strength of CGI allows engines to perform at higher pressure and also to have better efficiency with lower emission rate. The machinability of CGI is an area that needs to be studied in a better way to cut the production cost of the engine. It is a well know fact that the as-cast engine block

Lubrication Machining of Compacted Graphite Iron

machining of compacted graphite iron, formation of such a layer does not occur since the normal amount of sulfur added to CGI is around 0.01%, which is approximately ten times lower than that added to gray iron. In addition, the residual sulfur in compacted

Metallographic preparation of Cast iron Application Notes

For making Compacted graphite iron (CG) the same raw material is used as for mak-ing ductile iron. By carefully controlling the amount of magnesium added to the melt for nodulizing approx. 80% of graphite is formed as compacted graphite, the rest as nodules.
