AK12M2 (AK11M2) Aluminum Casting Alloy
Designation
Description
Material overview
AK12M2 and AK11M2 are regional designations for aluminum-silicon-copper casting alloy encountered on drawings for shaped castings. The exact grade and governing standard must be identified because designation usage and allowable composition can vary by document. Casting method, wall thickness and required final properties also affect feasibility.
Product forms and sourcing
Supply can be reviewed for available alloy feedstock, pressure-die cast or other specified castings, proof-machined parts and finished components. Include the drawing, casting route, rough and finished weight, machining allowance, dimensional tolerances, critical surfaces, tooling responsibility and expected release quantities.
Evek LLC reviews each requirement against the requested grade, specification, form, dimensions and quantity. Availability, origin, mill route, minimum quantity and certification are confirmed during quotation; website text is not a stock or compliance guarantee.
Specification and substitution
Do not substitute another aluminum casting alloy solely because the nominal silicon or copper content appears similar. Fluidity, hot-cracking behavior, porosity control, heat-treatment response, corrosion performance and mechanical properties may differ. Any alternative must be approved for the part and manufacturing route.
The purchaser remains responsible for material selection, design approval and confirmation that the specified material is suitable for the finished component, manufacturing process and service environment.
