Aleación de aluminio 6023

What Is 6023 Aluminum Alloy?

6023 aluminum is a lead-free free-machining Al–Mg–Si alloy that uses tin (and related elements) instead of lead to improve chip control. It is aimed at high-volume precision machining of automotive and electronic components where environmental compliance matters.

Guía para la selección del temple

6023 is typically supplied in O, T6, and T651. T6 / T651 are the machining tempers, giving the strength and stability needed for precision turned and milled parts. O is used where forming precedes machining.

Características principales

Lead-Free Machinability

Tin-based composition delivers chip control comparable to leaded alloys while meeting RoHS/REACH.

Optimized Chip Control

Produces short, manageable chips that reduce bird-nesting on automatic lathes.

Alta resistencia

T6/T651 tempers support demanding precision components.

Buena resistencia a la corrosión

Better atmospheric resistance than 2xxx series alternatives.

Excellent Anodizing

Responds well to decorative and hard-coat anodizing for a uniform appearance.

Aplicaciones

• Automóvil: brake components, fuel-injection parts, hydraulic valves
• Electrónica: connector bodies, sensor housings, precision pins
• Pneumatics & hydraulics: manifolds, pistons, fittings
• Sujetadores: high-precision nuts, bolts, threaded inserts

Notas sobre el procesamiento y el acabado superficial

6023 is supplied in heat-treatable tempers and supports standard aluminum fabrication:

• Corte: shearing, sawing, and laser cutting to size
• Mecanizado: CNC turning and milling; free-machining variants suit high-volume automatic lathes
• Soldadura: TIG/MIG weldable; note that welding reduces heat-treated strength in the weld zone
• Conformado: O and T4 tempers form well; T6/T9 are used near-finished
• Acabado superficial: anodizing (decorative and hard-coat) and polishing for visible parts

Documentación de calidad e inspección

Every order ships with a Mill Test Certificate (MTC) that reports the actual chemistry and mechanical results for the supplied lot. Inspection is available against ASTM, EN, or GB standards on request. Typical documents include:

• MTC (EN 10204 3.1): per-heat chemical and mechanical verification
• Dimension report: thickness, width, OD, and length tolerances per ordered specification
• Surface & packaging inspection: finish, edge, and export packaging photos on request

Linsy holds ISO 9001 (quality), ISO 14001 (environment), and ISO 45001 (occupational health and safety) certifications. Third-party SGS or comparable test reports can be arranged when the project requires them.

6023 Aluminum FAQ

Is 6023 lead-free?

Yes. 6023 is a lead-free free-machining alloy that meets RoHS and REACH requirements, using tin instead of lead for chip control.

6023 vs 6262 / 2011?

6023 is the lead-free counterpart aimed at the same free-machining role as 6262 and 2011, offering comparable chip control with better environmental compliance.

Is 6023 heat-treatable?

Yes. It is supplied in O, T6, and T651 tempers, with T6/T651 used for machined parts.

Preguntas frecuentes generales sobre pedidos

What information should I provide for a quote?

Alloy and temper, required form (sheet, plate, tube, bar, profile), dimensions and tolerances, quantity, and the applicable standard (ASTM, EN, GB, or JIS). Drawing-based profiles need a CAD file or dimension sketch.

What are the typical lead times?

Standard stock sizes are usually shipped within 10–60 days depending on specification and volume. Custom tempers, widths, or machined parts are quoted case by case.

Do you provide Mill Test Certificates?

Yes. An MTC reporting chemistry and mechanical properties for the supplied lot is provided with every order.

Can Linsy handle processing and finishing?

Yes. We offer CNC machining, laser cutting, welding, anodizing, and polishing so parts can be delivered closer to finished form.

Which standards do you supply to?

Commonly ASTM B209/B221/B210, EN 485/573/755, JIS H4000, and GB/T 3190/3880, among others. Confirm the exact standard when requesting a quote.
