Aluminum CNC Parts

Custom aluminum CNC parts for lightweight structures, housings, thermal components, and precision assemblies, with alloy and finish chosen for the application.

Aluminum CNC Parts

Aluminum machining from alloy selection through finished, inspected components.

Aluminum is widely used because it machines efficiently, offers a useful strength-to-weight ratio, and accepts many finishes. The right alloy depends on structural load, corrosion exposure, weldability, form, and whether anodized appearance or electrical performance matters.nnMilling, turning, EDM, and secondary cutting can be combined to produce detailed aluminum components. DFM review protects thin walls, reachable internal corners, and tolerances that affect the assembly.

Typical aluminum parts

Housings and enclosures

Brackets and frames

Heat sinks

Manifolds

Covers and panels

Fixtures and jigs

Shafts and adapters

Custom prototypes

By Machining Process

3-axis and 5-axis milling

Creates pockets, faces, compound contours, and multi-hole patterns with stable workholding.

CNC turning

Produces round parts, bores, threaded forms, and concentric features such as spacers and adapters.

EDM and secondary cutting

Wire EDM, sinker EDM, and related methods support fine internal profiles or features unsuitable for standard cutters.

Complementary cutting

Sawing, laser cutting, and waterjet preparation can efficiently create blanks before precision machining.

By Aluminum Alloy

Aluminum 6061

A versatile structural grade with good machinability, corrosion resistance, and finishing response.

Aluminum 7075

A high-strength option for loaded components where weight efficiency is important.

Aluminum 5052

Useful for corrosion-resistant components and formed-sheet related applications.

Aluminum 2024

A high-strength aerospace-oriented alloy used where its specific properties are required.

Aluminum 6063

Often chosen for extruded forms and parts that benefit from a good surface finish.

By Surface Finish

Type II anodizing

Provides corrosion protection with clear or colored cosmetic options.

Type III hardcoat

Adds a thicker, wear-resistant oxide layer for high-contact aluminum surfaces.

Bead blasting

Produces a uniform matte texture before anodizing, coating, or final delivery.

Powder coating

A durable colored finish for external housings, frames, and brackets.

By Inspection

Tolerances and inspection

Critical datums, holes, and profiles are measured against the drawing using methods appropriate to the feature.

First article inspection

An initial dimensional report can confirm agreed key characteristics before production proceeds.

Material records

Alloy identification and supplied certificates can be coordinated when specified.

Assembly fit checks

Thread, insert, bore, and mating features can be verified to reduce downstream assembly risk.
