Custom CNC Machined 7075 Aluminum Parts We Build
A quick selection of CNC machined 7075 aluminum components produced from customer drawings. These examples span hydraulic fluid parts, UAV and RC structures, impellers and general machinery components — all custom machined 7075 aluminum parts made to order in 7075-T6 / 7075-T651 temper.
Why 7075 Aluminum for Custom Machined Components
7075 is an Al-Zn-Mg-Cu series high strength aluminum alloy and a standard aerospace grade aluminum. In the 7075-T6 temper it typically reaches an ultimate tensile strength around 503–572 MPa and a yield strength around 435 MPa, at a density of roughly 2.81 g/cm³ — giving CNC machined 7075 aluminum parts a strength-to-weight ratio close to mild steel while remaining roughly one third of its weight. This combination is exactly why custom 7075 aluminum machining is preferred for loaded structures, wear-sensitive machinery parts, aerospace and defense components, and high-performance automotive and EV parts.
Our custom CNC machined 7075 aluminum alloy parts are produced from traceable plate, round bar, flat bar, forged block or extruded pre-form, in 7075-T6, 7075-T651 and 7075-T6511 tempers according to the drawing.
Material Characteristics
7075 offers very high static strength, good fatigue performance, high hardness (typically around 150 HB in T6 condition) and excellent stiffness for thin-walled, lightweight structures. Stress-relieved 7075-T651 plate stays dimensionally stable during and after custom 7075 aluminum fabrication, so large base plates, mounting plates, valve blocks and housings hold flatness without post-machining movement. Its natural corrosion resistance is lower than 6061, which is why anodizing, hard anodizing, chromate conversion coating or passivation are commonly specified as a final finish.
CNC Machinability of 7075
7075 machines freely with short, brittle chips and low cutting forces, which makes 7075 aluminum CNC machining well suited to high speed machining, heavy depths of cut and micro machining of fine features. Sharp polished tooling, high spindle speeds and proper coolant produce clean burr-free edges, fine wall finishes and thin ribs down to small section sizes. In the T6/T651 temper the alloy machines to tight tolerance without significant work hardening, and turn-mill or Swiss setups complete CNC machined 7075 aluminum parts in a single clamping for best concentricity.
Heat Treatment Methods
- T6: solution heat treatment followed by artificial aging — the default peak-strength temper for most 7075 machined parts.
- T651 / T6511: solution treated and stress-relieved by controlled stretching before aging; preferred for machined plates and bars to minimize distortion.
- T73: solution treated and over-aged to improve resistance to stress-corrosion cracking in thick aerospace sections.
- O temper: fully annealed, soft condition used for severe forming before re-aging.
T6 heat treatment is normally completed at raw-material stage; rough machining, stress release and finish machining are then staged to protect final accuracy.

7075 Aluminum Fabrication Beyond Solid-Block Machining
When a CNC machined 7075 aluminum part is large, curved or material-intensive, a formed pre-form often reduces cost and improves mechanical properties. Our custom 7075 aluminum fabrication service combines the following forming routes with finish CNC machining, delivering a near-net blank and a precision-machined final component in one order.
Aluminum Forging
Aluminum forging — including hot forging for high-strength structural shapes and cold forging for small symmetric parts — refines the grain flow of 7075 before machining. Forged control arms, connecting rods, cylinder parts and aviation structural components gain higher toughness and fatigue life than parts cut purely from plate.
Aluminum Extrusion
Custom aluminum extrusion profiles are produced to a cross-section drawing, aged to 7075-T6 temper, then cut and CNC finished. Extrusion-to-machining is an economical route for linear guide components, heat sink profiles, frames, rails and long housings used in automation equipment parts.
Sheet Metal Fabrication
Sheet metal fabrication of 7075 sheet covers stamping of shallow forms, precision bending of brackets and panels, laser or water-jet blanking, and secondary CNC trimming. It suits electronic enclosures, battery tray parts, shields, covers and lightweight chassis panels that later receive machined datum faces.
Welding & Die Casting
TIG / MIG welding joins 7075 assemblies where the design allows compatible filler selection, while die casting produces complex near-net blanks that are subsequently CNC machined on sealing and mating surfaces. Welded or cast fabrications are stress-relieved before final machining to safeguard flatness and tight tolerance.

How 7075 Aluminum CNC Parts Are Machined and Inspected
Every custom machined 7075 aluminum component follows the same controlled route: material verification against the specified 7075-T6 / 7075-T651 temper, CAM-programmed roughing and finishing on dedicated CNC equipment, staged deburring and surface treatment, then dimensional verification before packing. Calibrated measuring tools — vernier calipers, outside and inside micrometers, bore gauges, height gauges, thread gauges, hardness testers, surface-roughness testers, 2D profile projectors and coordinate measuring machines — support first-article, in-process and final inspection of tight tolerance features.
CNC Milling Service
3-axis, 4-axis and 5-axis CNC milling centers cut pockets, contours and complex 3D surfaces on custom 7075 aluminum machining work, including high speed machining of thin-walled structures.
CNC Turning Service
CNC lathes, Swiss turning machines and turn-mill centers produce shafts, bushings, fittings and other rotational 7075-T6 aluminum CNC parts with controlled concentricity and fine surface finish.
2D Profile Projector Measuring
Optical profile projectors verify small radii, chamfers, thread profiles and complex outline dimensions on micro-machined and Swiss-turned 7075 machined components without contact deformation.
CMM Testing
Coordinate measuring machines inspect position, true position, flatness, perpendicularity and profile of high precision ±0.01mm features, recording measured data for each batch of 7075 machined parts.
From One Prototype to Mass Production of 7075 Parts
Custom 7075 aluminum fabrication does not require large minimum quantities. We scale tooling, fixturing and inspection depth to the order size, so designers and procurement teams can move smoothly from first article to serial delivery without changing supplier.
One-Off & Prototype Machining
A single CNC machined 7075 aluminum prototype or sample-verification part is fully supported. Prototype machining includes DFM feedback, soft-tool fixturing, rapid CNC milling or turning, and first-article measured reports — ideal for design validation of robot parts, drone parts, racing components and custom machinery.
