Zamak 7: Confirm the Full Callout Before Machining
For your Zamak 7 die casting and Zamak 7 machining review, confirm the ordered product and drawing. Zamak 7 properties and Zamak 7 composition should be read alongside the required filling, surface finish, assembly and inspection conditions.

Your European and Supplier Names
| Name | Your approval boundary |
|---|---|
| Zamak 7 / Alloy 7 | IZA also uses ZL7. No numeric EN casting code is assigned here. |
| HF / high-fluidity families | Confirm the exact supplier designation and specification; the family name is not one composition. |
| Proprietary zinc alloys | Confirm owner specification, supply authorization and agreed product route. |
| Customer material callout | Approve the complete standard, revision and any proposed substitution. |
IZA describes Zamak 7 as a lower-magnesium modification of Alloy 3, with tighter impurity control. Your Zamak 7 die casting services review should confirm the actual geometry and finish requirements rather than promise a universal wall thickness.

Answers Before You Specify Specialty Zinc Alloy
Can you cast customer specified zinc alloys?
Send the complete material callout, controlled drawing, product form, proposed casting route and quantities. Availability, process fit, tooling and required records are reviewed for your quotation; not every proprietary grade or route is automatically available.
How should you specify Zamak 7?
Retain the full alloy and product specification, revision and impurity requirements. Zamak 7 / Alloy 7 and the IZA ZL7 name are references; no numeric EN casting code is assigned here.
Can Zamak 7 be machined?
Review locating support, allowance, bore and thread access, accepted burrs and final coating with the actual casting. Material identity does not remove the need to approve the finished fit.
Can a high-fluidity alloy replace Zamak 7?
Only after reviewing the complete supplier specification, geometry, mechanical requirements, finish and receiving criteria with the drawing authority. A family description is not substitution approval.
What if your European drawing uses a different name?
Provide the full designation, standard, revision and required product form. Confirm cast-part versus ingot/liquid references and approve the actual ordered chemistry and records.
What information makes special-alloy quotations comparable?
Use the same controlled drawing, exact material, casting route, quantities, finish, critical fits and inspection scope. Include tooling ownership and expected repeat demand.
Can one composition table cover all specialty zinc alloys?
No. The selected Zamak 7 table is a reference for that grade. Proprietary and customer-defined alloys need their own full specification and material-lot evidence.
How should you define final functional acceptance?
Identify the mating parts, service environment, loads and duration, final coating and measurement state. Agree dimensional, appearance and any separate integrity or duty tests.
