Mesh2Metal provides custom aluminum parts fast from customer CAD files. The sequence is additive manufacturing, parts built near-net shape, precision machining where specified, inspection, and a quality certificate. Typical delivery is next day to 5 days; maximum part size is 800 × 800 × 600 mm.

## What are the specifications for aluminum parts?

Aluminum part specifications start with a typical density range of 2.60–2.85 g/cm³ across the four listed families. Maximum part size is 800 × 800 × 600 mm, with larger parts on request. Machined features are ±0.1 mm standard or ±0.05 mm precision; as-built surfaces are ±0.5 mm. Delivery runs from the next day up to 5 days depending on part size, and the exact date comes with the instant quote. Quantities from 1–200 are available with no tooling.

## Why choose aluminum for lightweight housings and brackets?

Aluminum selection usually starts with weight. The listed families have low density for an engineering metal, so lightweight aluminum housings and brackets can reduce mass while retaining useful stiffness and dimensional stability. Lower mass can simplify handling, packaging, and integration where every part contributes to the overall assembly.

Aluminum also conducts heat effectively compared with many common engineering metals. That makes aluminum a practical choice for heat-spreading housings, covers, and brackets around warm components. State any thermal-property requirement in the part description; the quality certificate includes thermal properties.

Corrosion behavior depends on grade, surface condition, and exposure. Aluminum performs well in many normal environments, but humidity, salt, chemicals, and outdoor service can change the selection. Describe the environment and the required service life so the selected family matches the application.

## Which aluminum grades are available?

Aluminum grade selection balances density, strength, heat-treatability, corrosion response, and intended use. The table gives family-level guidance; confirm the exact alloy and condition for a released design.

| Grade family                    | Density (g/cm³) | Heat-treatable? | Typical use                                       |
| ------------------------------- | --------------- | --------------- | ------------------------------------------------- |
| Al-Si AlSi5-class               | 2.65–2.68       | No              | General housings, covers, and brackets            |
| Al-Si AlSi12-class              | 2.60–2.65       | No              | Thin-wall housings, covers, and detailed geometry |
| Al-Mg AlMg5-class               | 2.64–2.67       | No              | Lightweight brackets and enclosures               |
| Al-Cu 2xxx-class heat-treatable | 2.75–2.85       | Yes             | Higher-strength brackets and structural housings  |

If a design needs a specific wrought grade such as 6061-T6 or 7075, tell us in the part description and we’ll confirm.

## How should I design aluminum housings and brackets?

Aluminum design notes should separate minimum walls from machined features. As-built minimum walls depend on the actual geometry and required stiffness; do not reuse a wall value from a different part. Keep walls that must carry load or seal identified in the design, and use the manufacturability check to review the CAD. Machined features can carry tighter tolerances than as-built surfaces, so reserve precision for bores, bearing seats, sealing lands, and mounting faces that need it.

Datums should follow functional references. Identify the primary mounting face as datum A, a secondary locator as datum B, and a clocking feature as datum C when that scheme matches the part. Dimension hole patterns and critical faces from those datums rather than from an arbitrary edge. Call out which features are inspection-critical and which remain as-built.

Brackets should show fastener-hole locations and load-bearing faces. Housings should identify sealing lands, cover interfaces, and any face that interfaces with another component. A precise description helps the instant manufacturability verdict explain why and how to fix it when a design needs a change.

Drop your CAD to begin a check; supported formats are STL, STEP/STP, 3MF, and OBJ. The files are analyzed locally in the browser and never leave your device.

## Which finishes are available for aluminum parts?

Aluminum finish selection should follow function and appearance. Available finishes are as-built, machined, polished, and media-blasted. As-built surfaces are typically Ra 12–25 µm. Machined surfaces are Ra 3.2 µm standard, with 1.6 µm optional.

Polished and media-blasted surfaces can support different visual goals; identify any face that must retain a dimension or datum relationship. Finish requests should include target roughness, critical dimensions, and whether the finish applies before or after precision machining.

## What does the aluminum quality certificate include?

The aluminum quality certificate accompanies every part. Certificate items include chemical composition, porosity and defect map, 3D deviation from your CAD, mechanical properties, thermal properties, traceability, and certificate of conformance. Use the certificate to keep material, dimensional, and inspection records with the part revision.

If procurement or quality teams need a named field, put it in the part description before the instant quote. Clear requirements make the resulting certificate easier to review against the released CAD and datums.

## How fast can Los Angeles teams get aluminum parts?

For aluminum metal parts on demand in Los Angeles, Mesh2Metal operates in El Segundo, in the South Bay next to LAX, within a dense aerospace and space ecosystem. The service supports one-off and short-run needs: parts are made in under 1 day, delivery is next day up to 5 days depending on part size, and quantities from 1 to 200 are supported with no tooling. The exact date appears with the instant quote.

## Questions

Can I specify a wrought aluminum grade?

If a design needs a specific wrought grade such as 6061-T6 or 7075, tell us in the part description and we'll confirm.

Can one aluminum part use multiple alloys?

A single part can use up to 3 alloys. Put the alloy combination and the function of each region in the part description.

Can my CAD files stay on my device?

STL, STEP/STP, 3MF and OBJ files are analyzed locally in the browser and never leave your device.

What should I do with export-controlled technical data?

Please don't send us export-controlled (ITAR/EAR) technical data until we have set up a compliant path with you — contact us first.
