# Aluminum Alloy Selection for Gravity Casting RFQs
Aluminum alloy selection should start from the part function, not the cheapest material name. A buyer preparing a gravity casting RFQ should define mechanical requirements, heat treatment, pressure or load risk, machining exposure, surface finish, and inspection records.
Buyer decision points
- •Is the part load-bearing, pressure-related, cosmetic, or thermal?
- •Will sealing faces, ports, or bores be machined after casting?
- •Is heat treatment required?
- •What material certificate or test record is needed?
- •Is an equivalent alloy acceptable if it meets the drawing requirement?

Send the drawing, target alloy, finishing scope, MOQ, and delivery timing. Bohua will review it like a real sourcing project, not a generic contact request.
Supplier comparison
Ask suppliers to explain why A356, ZL114, ADC12, or another alloy fits the drawing and process route. The answer should reference function, casting route, machining, inspection, and approval evidence.
