A356 / AlSi7Mg
Common casting family for housings and structural shapes; properties depend strongly on casting quality and heat-treatment condition.
MATERIAL GUIDANCE
Aluminum Alloy
Aluminum alloys combine low density with useful strength, corrosion resistance and machinability. The correct grade depends on whether the part is cast, die cast, forged or machined from wrought stock, as well as its load, temperature, appearance and finishing requirements.

GRADES & SELECTION FACTORS
Confirm the exact specification before quotation.
Grade names and standard systems must be checked against the drawing, application and requested documentation.
A380 / ADC12
Widely used high-pressure die-casting alloys for complex, repeat-volume parts; exact chemistry and naming system must be specified.
6061
Commonly machined or forged rather than die cast; temper such as T6 is part of the material requirement.
Low density
Supports weight reduction, but stiffness and section design still require engineering review.
Corrosion behavior
Naturally forms an oxide layer; service environment and galvanic contact can still require protection.
Castability and detail
Silicon-bearing casting alloys can fill complex shapes; wall thickness and porosity risk depend on process and geometry.
Machinability
Often machines efficiently, although alloy, temper, casting skin and internal porosity affect results.
ENGINEERING NOTES
Selection, processing and finishing considerations.
Use these points to confirm the material specification, manufacturing route and finishing scope before quotation.
Separate casting and wrought grades
A wrought designation should not be substituted automatically for a casting alloy. Confirm the required production route, alloy designation and temper on the drawing or RFQ.
Define critical function
Identify pressure containment, sealing faces, fatigue loads, thermal exposure, cosmetic surfaces and any leak-testing requirement before process selection.
Control interfaces
Provide datums, machining allowances, threaded features and mating-part information so casting and machining controls can be planned together.
Heat treatment
Heat-treatment condition can materially change strength and dimensional stability. Specify the required temper and whether properties apply to test coupons or the finished part.
Surface finishing
Anodizing, conversion coating, painting, powder coating and plating require alloy- and surface-specific preparation. Cosmetic class, masking areas, color and corrosion-test requirements should be stated.
Verification
Agree whether chemistry, mechanical properties, porosity evaluation, pressure testing, coating thickness or other records are required.

FAQ
Questions to clarify before quotation.
Final answers depend on the drawing, material specification, quantity, application and required documentation.
Can 6061 be used for a die-cast part?
6061 is primarily a wrought alloy. A die-casting alloy with suitable performance should be selected through drawing and application review.
Which aluminum alloy is best for pressure housings?
There is no universal choice. Geometry, casting route, pressure, leak rate, heat treatment and machining all influence the selection.
Will anodizing hide casting defects?
No. Finishing may make porosity, flow marks or surface variation more visible, so the cosmetic requirement must be agreed before production.
What should an aluminum RFQ include?
Provide alloy and temper, drawing revision, process or product form, quantity, critical tolerances, finish, inspection and service conditions.
