Low weight
Useful for moving assemblies, handheld products, brackets, housings and frames where mass reduction matters.
Metal material
Aluminum Manufacturing and Custom Parts
A lightweight metal family used for machined housings, brackets, fixtures, and structural parts.
- Lightweight
- Machinable
- Corrosion resistant
Material overview
A broad material family for lightweight precision manufacturing.
Aluminum is often selected when a part needs low weight, useful strength, corrosion resistance, and good compatibility with machining and finishing processes. It supports prototypes, fixtures, housings, panels, brackets, heat sinks, and structural components when the specific alloy is matched to the application.
This page covers the general aluminum family. For controlled production drawings, Kewei reviews whether a grade such as 6061 or 7075 is required, how stock form affects the result, and whether anodizing, machining allowance, cosmetic surfaces, or inspection documentation change the manufacturing plan.
Key properties
Performance characteristics translated into manufacturing decisions.
Good machinability
Many aluminum grades can be milled, turned, drilled and threaded efficiently when workholding and tool access are planned.
Finish compatibility
Anodizing, bead blasting, brushing, painting and conversion-style treatments can be reviewed against the alloy and cosmetic target.
Thermal conductivity
Aluminum is commonly considered for heat sinks, covers and instrument parts where heat transfer is part of the design.
Suitable processes
Manufacturing routes for this material.
Compatible Surface Finishes
Surface options reviewed with the base material.
Typical applications
Common Aluminum part families.
Machined housings
Automation brackets
Heat sinks
Instrument panels
Prototype enclosures
Lightweight frames
Design considerations
Control the features that affect function and process stability.
G 01
Choose a specific grade such as 6061 or 7075 when the drawing has structural or documentation requirements.
G 02
Mark visible faces, grain direction, masking areas and color standards before finishing.
G 03
Separate general tolerances from critical fits, threads and sealing surfaces.
G 04
Review heat dissipation, electrical contact or isolation needs before selecting the finish.
Limitations
Requirements that need engineering review.
- Aluminum is not a single specification; grade and temper affect strength, corrosion behavior and finish response.
- Thin walls, deep pockets and asymmetric machining can distort without staged processing.
- Anodized color and cosmetic appearance can vary by alloy, preparation and batch.
- Wear surfaces, threaded inserts and loaded contact points may need design reinforcement or another material.
RFQ checklist
Material details to include in the quotation package.
Clear requirements help engineering, finishing, inspection, and purchasing review the same target.
- 01Target alloy and temper, or permission for Kewei to recommend options
- 023D model and controlled drawing with critical dimensions
- 03Finish type, color, masking and cosmetic acceptance requirements
- 04Quantity, inspection level, certificates and delivery target

FAQ
Aluminum questions from engineering and sourcing teams.
Should an RFQ say aluminum or name a specific alloy?
If function, strength, certificates, corrosion exposure or finish appearance matters, name the required alloy and temper. If the design is still open, Kewei can review candidate grades with the drawing.
Can aluminum parts be anodized after machining?
Yes, many aluminum parts are anodized after machining. The alloy, surface preparation, masking, color and dimensional allowance should be confirmed before production.
How does this page relate to Aluminum 6061 and 7075 pages?
This page explains the general aluminum family. The 6061 and 7075 pages provide grade-specific guidance for common production decisions.
