AZ91D Machining for Cast Housing, Machined Bores & Final Seal
Your AZ91D machining review should protect the interfaces that control sealing and assembly. Define the cast housing, stock allowance, bore datums and protective finish before tooling approval.

AZ91D vs AM60B: Strength and Ductility Need the Same Test Basis

4 review topics connect the material to your drawing. Keep the delivered product and receiving criteria explicit.
Your AZ91D Overview
For your AZ91D die-casting housing, identify pressure boundaries, gasket lands and any specified leak test separately from dimensional inspection. Machining can expose subsurface porosity; agree the acceptance route for your finished part.
| Your reference | What to define |
|---|---|
| Your material | Magnesium–aluminum–zinc die-casting alloy |
| Your route | Die casting + secondary machining |
| Your drawing | Critical interfaces, allowable deformation and final fit |
Your AZ91D Route & Condition
For your AZ91D prototype parts, distinguish a geometric fit sample from production-route validation. Confirm the casting process, machining allowance, support and inspection state. Do not assume a machined billet reproduces die-cast properties.
| Your reference | What to define |
|---|---|
| Incoming condition | Specification, product form, lot and usable allowance |
| Working features | Datums, cutter access, bores, threads and accepted edges |
| Your approval | First sample in the agreed measurement state |
Your AZ91D Finish & Fit
For your AZ91D surface treatment, review exposure and mating metals before choosing a protection system. Define masked contact lands, thread coverage, gasket surfaces and dimensions after finishing.
| Your reference | What to define |
|---|---|
| Your environment | Moisture, chemicals, storage, temperature and duration |
| Your assembly | Contact materials, isolation and electrical requirements |
| Your final fit | Coating build, masked lands and measurement condition |
Your AZ91D Inspection & Records
Link material identity to your controlled drawing and the finished measurement state. Dimensional inspection does not establish corrosion life, energy absorption or pressure integrity.
| Your reference | What to define |
|---|---|
| Material & lot | Full callout and material-lot evidence |
| Dimensional records | Critical features, agreed methods and sampling |
| Functional evidence | Separate load, leak or finish test when specified |
3 Decisions Before Your AZ91D Order
Keep supply, sample purpose and coating acceptance in the same drawing review.
Your Material Source
Confirm AZ91D supplier scope: raw material, cast blank or finished component. Availability and certificates are reviewed for your specific order.
Your Sample Purpose
Agree geometry, mating features and test purpose. A successful fit check alone does not validate production properties.
Your Finish Acceptance
Define the complete protection system, visible faces, masked lands and receiving inspection in the final state.
COMPOSITION AND PRODUCT SCOPE
Your AZ91D Composition Reference
Selected NADCA 2015 ASTM B94-03 die-cast part reference, p. 3-21. Use the complete ordered revision and impurity requirements, not this selected table alone.
For your material analysis report, agree the complete element list, ordered limits, method and lot identity. The reference table is not a test of the illustrated component.
| Selected element | wt.% reference |
|---|---|
| Al | 8.3–9.7 |
| Zn | 0.35–1.0 |
| Mn | 0.15–0.50 |
| Mg | Balance |

IMS lists the ISO symbol and number for ingots. NADCA 2015 lists AZ91 in its EN 1753/1997 cross-reference. The D suffix, impurity limits and ordered cast-part specification must remain explicit.

Answers Before You Specify
What is AZ91D magnesium alloy?
Magnesium–aluminum–zinc die-casting alloy. Select the exact product specification and final condition around your drawing; the family name alone is not purchasing acceptance.
Can AZ91D die cast parts be machined?
Review stock allowance, datum support, cutter access, bores, threads, accepted edges and the final coating. Machining may expose subsurface porosity; agree any separate integrity test.
What information is needed for an AZ91D die casting quote?
Send controlled CAD and drawing, full material and product specification, route and delivery state, quantities, finish, critical fits and inspection needs. Tooling, trial and repeat demand should be separated.
What is the minimum order quantity for AZ91D parts?
Quantity, tooling, available material, process route and inspection scope determine the reviewed commercial basis. No fixed MOQ or delivery promise is assigned here.
How can AZ91D parts be protected from corrosion?
Define exposure, temperature, duration and mating metals. Review a compatible preparation and coating system, isolation, masked lands and dimensions after finishing. AZ91D corrosion resistance is not a universal coating-life guarantee.
Can one magnesium alloy replace another?
Obtain drawing-authority approval after comparing complete product specifications, delivery states, service conditions and finished acceptance. Similar names do not establish equivalence.
What changes your AZ91D quotation?
Material sourcing, geometry, usable stock, tooling, secondary machining, protection system, quantities and required records change the reviewed price. Compare the same drawing revision and acceptance scope.
Can published properties replace your inspection report?
No. Published reference values describe their stated product and test basis. Your receiving evidence needs actual material-lot identity, agreed dimensional records and any separately specified functional tests.
