6022 铝合金

What Is 6022 Aluminum Alloy?

6022 aluminum is a heat-treatable Al–Mg–Si alloy engineered for automotive body and structural sheet. It combines good T4 formability with a strong strength gain during paint-bake curing, supporting lightweight, corrosion-resistant vehicle structures.

硬度选择指南

6022 is supplied in O, T4, and T6. The T4 temper is used for parts that are formed and then aged during paint curing; T6 is used where strength is required up front. Pick T4 for complex formed panels and T6 for structural reinforcements.

主要特点

Strong Paint-Bake Response

Gains substantial strength during the paint-cure cycle, key for lightweight body design.

Excellent Formability (T4/O)

Forms cleanly before aging, reducing springback and press issues.

良好的耐腐蚀性

Suited to exposed automotive environments.

High Strength-to-Weight

Helps meet fuel-efficiency and emission targets.

Weldability & Recyclability

Compatible with high-volume automotive joining and recycling streams.

应用

• Automotive outer panels: hoods, doors, fenders
• Automotive structural parts: reinforcements and crash-relevant components
• Heat shields and brackets: light structural stampings
• Appliance panels: covers and enclosures

加工与表面处理说明

6022 is supplied in heat-treatable tempers and supports standard aluminum fabrication:

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

质量文件与检验

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.

6022 Aluminum FAQ

Is 6022 heat-treatable?

Yes. 6022 is a heat-treatable 6xxx alloy in O, T4, and T6 tempers.

6022 vs 6016?

6022 is aimed at both body and structural use with a strong paint-bake response, while 6016 is a classic outer-panel alloy. Choose 6022 when structural strength alongside formability is required.

What is the paint-bake benefit?

6022’s strength rises during the paint-cure oven cycle, so formed parts age-harden without a separate heat-treat step.

常见订购问题解答

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.
