Yes, pot metal is used for die casting. Pot metal, a term for low-cost, low-melting-point alloys (often zinc, aluminum, tin, or lead-based), is commonly used in high-pressure die casting to produce inexpensive, non-structural parts like decorative hardware, small fittings, or low-cost door knobs. Its low melting point and good flow properties make it suitable for casting intricate shapes, but it’s less durable and prone to defects, limiting its use in high-strength applications like aircraft component.
