This blog explores how graphite solutions by Delmer Group enhance furnace performance, improve casting quality, and optimize production efficiency.

What is Graphite and Why is it Used in Furnaces?

Graphite is a form of carbon known for its:

• High thermal resistance (up to 3000°C in inert conditions)
• Excellent thermal conductivity
• Low thermal expansion
• High resistance to chemical corrosion

These properties make graphite ideal for applications involving molten metals such as gold, aluminum, copper, brass, and steel.
