What is the best CPC for ductile iron?

Low-sulfur CPC is commonly selected for sulfur-sensitive foundry applications.

What packaging is available for CPC?

CPC is commonly supplied in jumbo bags, or 25 kg bags combined with jumbo bags. Customized packaging can also be arranged according to handling requirements.

How does CPC differ from GPC?

CPC is for reliable carbon sources with competitive costs, while GPC is for low sulfur and high purity needs.

Product Q&A

Q:Is CPC suitable as a carbon raiser?

Yes. CPC is a widely used carbon raiser for steelmaking and foundry applications. Buyers typically select CPC based on fixed carbon, sulfur, ash, moisture and particle size.

Q:What CPC particle size should I choose?

Common CPC carbon raiser sizes include 0-1 mm, 1-3 mm and 1-5 mm. The right particle size depends on the furnace type, feeding method and required carbon recovery.

Q:Why is low sulfur important in CPC?

Low-sulfur CPC helps reduce unwanted sulfur input during melting. It is particularly important for foundries producing ductile iron and other sulfur-sensitive grades.

Q:Does CPC ash content matter?

Yes. Lower ash means a higher proportion of the CPC is effective carbon. Buyers should compare ash together with fixed carbon, sulfur and moisture when evaluating CPC suppliers.

Q:How should I compare CPC suppliers?

Compare CPC suppliers by fixed carbon, sulfur, ash, moisture, particle-size consistency, carbon recovery, COA, price and delivery reliability--not price per ton alone.
