Graphite Electrodes For Electrical Discharge Machining

Trustworthy shipping facilities, competent workforce and prompt delivery of the products make us stand out in the industry. To ensure maximum quality retention, we package our products in industrial-grade packaging materials that can brave mechanical damages and logistical jostling. Additionally, they are labeled to impart product information.

Applications :

• Our graphite has many advantages which are widely used as electrical discharge machining (EDM) electrodes for fabricating molds for die-casting, plastics and more. Graphite has the versatility to machine very large to small precision sizes used in the medical field.
• Compared to copper electrode, graphite electrodes offer excellent cutting performance and produce fewer burrs and similar issues, thereby enabling speed improvements in both cutting and EDM processes.

Features :

• Easy to machine
• High resistant to thermal shock
• Low coefficient of thermal expansion (3 times lower than copper) are able to ensure the stability of electrode geometry during process.
• Availability in large blocks.
• Not melt, but goes directly from the solid state to the gaseous at 3,400^oC, which reduces wear.
• Density is 5 times lower than that of copper, which results in lighter electrodes.
• Higher metal removal rate than copper with less wear.
• Unique characteristic that the wear ratio tends to decrease as the peak current increases.
