CI Sand Cast Gunmetal Castings" refers to castings made using the sand casting process, involving Cast Iron (CI) and Gunmetal, which are both common foundry materials but distinct metals. Here’s a breakdown to clarify the terminology and what it typically refers to:

• Composition: Iron + 2–4% Carbon + Silicon + Manganese

• Types: Gray Iron, Ductile Iron, White Iron, Malleable Iron

• Properties:

  • Excellent compressive strength

  • Good machinability (especially gray iron)

  • Brittle compared to steel

  • Poor corrosion resistance unless coated

• Composition: Primarily Copper (88–90%), Tin (~10%), and a small amount of Zinc or Lead

• Also known as: Red Brass or LG2 bronze

• Properties:

  • High corrosion resistance (especially in marine and water systems)

  • Good wear resistance

  • Easy to cast and machine

  • Non-sparking and non-magnetic
