  • Brief Introduction


                                                      

    Introduction

    Supply a wide range of High Purity Graphite blocks & rods & plates & sheets of different dimensions.
    Fine Grain Graphite Blocks & Rods & Plate are vibro-compacted and available in various sizes and grades. It is manufactured by fine grain petroleum coke. Its grain size depending on different production processes deeply affects the performance.

    Application

    Graphite Blocks / Plates / Rods/Sheets /Bars are variously used in many productions and applications, such as Mold , Batteries, Electric Motor Brushes, Alternator Brushes, Burner usage, Metallurgy, Semiconductor, Aviation, Chemicals, Energy, Nuclear and Glass Industry etc.
    Others: Hard Alloys, Graphite Mold, Diamond Aiguille, Saw Sinter Film, semiconductor Monocrystal Graphite Mold, Continuous Casting, Casting Steel, Alloys casting, Metals Casting, Graphite for Ray-cable, Graphite for Mid or Mini-type Rocket, Crucibles.
