Carbon Graphite
It is important to know what you’re receiving from your supplier when ordering carbon to make gray or ductile iron castings.
Our Carbon Graphite Offerings
Sometimes inferior carbon graphite will have a higher sulfur content that includes petroleum coke. This is to keep the price of the material low. The effect is creating an increase in the use of costly magnesium based alloys that could cause casting issues while making ductile iron.
Midvale Industries offers high quality natural carbon graphite with lower levels of sulfur that is produced in the U.S.A. Conversely when making gray iron, some sulfur in your carbon can actually aid in reducing inoculant usage, making petroleum coke a good option.
