5086 알루미늄 합금

What Is 5086 Aluminum Alloy Aluminum?

5086 Aluminum Alloy (AlMg4) is a non-heat-treatable aluminum-magnesium (5xxx) alloy. Its strength comes from magnesium in solid solution and strain hardening, not heat treatment. It offers good corrosion resistance—especially in marine and industrial environments—and welds well, which makes it a common choice for structures exposed to water, chemicals, or cycling loads.

템퍼 선택 가이드

• O (annealed): softest, best formability and corrosion resistance; for deep drawing and welding.
• H1xx / H2xx / H3xx: strain-hardened tempers with increasing strength and decreasing ductility.
• H116 / H321: stabilized tempers for marine plate with good exfoliation-corrosion resistance.

Choose the softest temper that meets the strength need to keep forming and welding straightforward.

주요 특징

Marine corrosion resistance

Good resistance to seawater and many industrial environments, suitable for hulls and offshore parts.

용접성

Welds readily with TIG/MIG and matching 5xxx filler; strength in the weld zone is close to the base metal.

Strength without heat treatment

Reaches useful strength through strain hardening, so no quenching or aging is needed.

애플리케이션

• Ship and boat structures
• Pressure vessels and tanks
• Welded marine fabrications
• Vehicle bodies and trailers
• Cryogenic and low-temperature equipment

가공 및 표면 마감 참고 사항

5086 Aluminum Alloy is a non-heat-treatable 5xxx alloy, so strength comes from strain hardening (H-tempers), not heat treatment. It cuts, drills, and welds well with standard aluminum tooling.

• 절단: CNC machining, laser cutting, and sawing are supported.
• 용접: TIG and MIG welding with matching or compatible 5xxx filler.
• 성형: good cold formability in O and soft H-tempers.
• Surface finish: mill finish, anodizing, polishing, powder coating, or PVC film protection.

Note: anodized color of 5xxx alloys can differ slightly from 6xxx alloys; confirm the finish on a sample if color match matters.

품질 문서 및 검사

Every 5086 order ships with a Mill Test Certificate (MTC) that reports the actual chemical analysis and mechanical results for the supplied material. Third-party SGS or equivalent test reports can be arranged on request for project or tender requirements.

• MTC (EN 10204 3.1 or 3.2) with every order
• Dimensional inspection against the agreed tolerance
• Surface and visual check before packing
• Material traceability by heat / lot number

5086 Aluminum Alloy Aluminum FAQ

Is 5086 heat treatable?

No. 5086 is a non-heat-treatable 5xxx alloy; its strength comes from magnesium content and strain hardening (H-tempers).

What filler is used to weld 5086?

Matching 5xxx fillers such as 5356 or 5183 are commonly used, depending on the parent alloy and service conditions.

5086 vs 5083 — which to choose?

Both are marine-grade 5xxx alloys. 5083 (Mg ~4.0–4.9) is typically used for higher-strength plate; 5086 is chosen where its formability and corrosion profile fit the job. Confirm with your design specification.
