Graphite Bar Technology: Professional FAQ

Q1. What is the difference between 1 4 graphite rod and 1 8 graphite rod?

A: The numbers refer to the diameter in inches. 1 4 graphite rod (1/4 inch ≈ 6.35 mm) is thicker than 1 8 graphite rod (1/8 inch ≈ 3.18 mm), affecting mechanical strength and current-carrying capacity. Selection depends on application demands for rigidity and conductivity.

Q2. What is the main material and purity grade for your graphite bars?

A: Our graphite bars use high-carbon, fine-grain synthetic graphite with carbon content typically >99.9% and ash content <0.05%, ideal for harsh environments and precision equipment.

Q3. What are the industry standard tolerances for graphite rod machining?

A: Diameter tolerance can be controlled to ±0.1 mm or better depending on request, fulfilling ASTM C561 and ISO 16179 standards for carbon products.

Q4. How are graphite bars installed in high-temp or corrosive environments?

A: Proper installation requires precise mechanical supports, controlled fastening, and sometimes ceramic or metal anchoring to avoid stress cracking. Our technical team provides installation guides tailored to your process.

Q5. What is the service life of a graphite bar under continuous use?

A: It depends on temperature, gas environment, load, and chemical exposure, but our fine-grain rods can retain mechanical integrity for hundreds to thousands of hours in typical molten metal service (see ResearchGate study).

Q6. Are your graphite bars compatible with custom finishes or coatings?

A: Yes, we offer anti-oxidation, nickel or copper plating for improved shelf life and electrical performance per your specifications.

Q7. How to select the right graphite rod for unusual or advanced applications?

A: Please provide details of your operational temperature, mechanical load, chemical contact and desired geometry — our team will recommend the best 1 4 graphite rod, 1 8 graphite rod, or custom solution for your process.
