Answers Before You Specify ZA-12
Is ZP1110 the same as ZA-12?
ZP12 / ZP1110 and ZnAl11Cu1 are common casting references associated with ZA-12. Retain the complete specification and revision. IZA lists ZL12 / ZL1210 separately for prototype alloys.
Can ZA-12 be cold chamber die cast?
Yes. Review the actual cold-chamber casting route, geometry, tooling and usable machining stock with your quote. Do not automatically apply a ZA-8 hot-chamber route.
Can ZA-12 be machined?
Yes. Identify locating support, usable allowance, bore and port access, accepted burrs and the final condition inspected after machining and finishing.
What information is needed for a ZA-12 casting quote?
Provide CAD and controlled drawing, grade and product standard, casting route, quantities, load and temperature, final finish, free or installed fit and receiving records.
Is ZA-12 suitable for bearing parts?
Review load, speed, temperature, lubrication, mating material and installed clearance. Request appropriate duty data and acceptance; alloy identity alone does not establish service life.
What causes porosity in ZA-12 castings?
Review casting route, section layout, feeding or filling approach and agreed defect limits with the foundry. Identify critical bores or sealing surfaces and any separately required integrity test.
What ZA-12 die casting tolerances can you quote?
Specify cast versus machined features, datums, limits and final finish. Your quote confirms the reviewed geometry and inspection scope, without a universal tolerance promise.
Can a gravity-cast prototype represent the production part?
Compare the actual route, material state and the property being tested. A prototype made by another casting process does not automatically reproduce die-cast mechanical behavior.
