# 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?

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.
