EDM Graphite

Graphite is a highly engineered material, with excellent machinability and its medium and premium grades have small particle size and high density. Combine that with very good electrical conductivity, and the result is the standard when it comes to material of choice for Sinker EDM applications.

Influence of Semi

In this research, the effect of semi-solid isothermal heat treatment on microstructure, hardness and impact toughness of ductile iron (DI) is studied. Heat-treated air-cooled ductile iron shows spheroid graphite, cementite and fine pearlite matrix structure. At the early

Cast iron

Cast iron is a group of iron-carbon alloys with a carbon content more than 2%. [1] Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as

Medium Graphite Blocks

Medium grain graphite blocks are ideally suited for large parts or components used for graphite furnace, polycrystalline silicon furnace, casting mold and crucibles. Unlike high purity graphite and isostatic graphite materials, medium grain graphite materials don't need to

Everything About Graphite

Of Pencils and Diamonds – Everything About the Versatile Material Graphite Almost all of us have had it in our hands at some time or another, mostly in the form of a pencil: Graphite. The term graphite is derived from the Greek graphein which means "to write".

Isostatic Graphite Block

Isostatic graphite block is produced by the method of Cold Isostatic Pressing (CIP). Graphite is isostatically pressed in a purpose of ensuring uniform properties in all grain directions. Isostatic Graphite is used for specific applications for which the homogeneity is

graphite

Electric arc furnace steelmaking is based on electrodes to generate arcs, so that electric energy can be changed into heat energy in the arc, melting furnace burden and removing impurities such as sulfur and phosphorus, adding necessary elements (such as carbon, nickel, manganese, etc.) to smelt steel or alloy with various properties. . Electric energy heating can accurately control the

The Role of Graphite in a Quality EDM Finish

Because the grade of graphite is the critical element in the EDM process, it is important to familiarize yourself with the various grades of graphite. Selecting graphite on price alone can result in a pitted or out of tolerance cavity that can cost thousands of dollars in
