Graphite Electrodes

ABL’s ranges of top quality graphite electrodes are produced using some of the world’s finest needle cokes and production techniques. This coupled with machining, testing, packing and distribution from our dedicated facilities, ensures our product and service remains consistent, cost effective and reliable.

ABL graphite electrodes are produced according to exacting standards authorized and monitored by our personnel.

ABL graphite electrodes are utilized by leading steel, foundry and fused mineral producers.


CHOOSING AN ELECTRODE

ABL works with new and existing customers to select the most suitable product for their applications, always ensuring that quality and cost effectiveness are guaranteed.


General product selection guide;

• ABL-RP Grade is recommended for use in ultra high power large capacity EAF and ultra high power large capacity LF applications.

• ABL-HP Grade is recommended for use in high power LF, Foundry and Fused Mineral applications.
