5082-O/H18/H38 알루미늄 와이어

What Is 5082 Aluminum Wire?

5082 aluminum wire is drawn from the same AlMg4.5 alloy used for 5082 sheet and plate, but delivered as coiled or spooled wire. Being non-heat-treatable, its strength is set by the temper: O is soft and formable, H18 is strain-hardened to a medium level, and H38 is the strongest of the three. The wire keeps the alloy’s good corrosion resistance and weldability, making it useful for rivets, fasteners, and welded assemblies.

Note that 5082 wire is distinct from aluminum welding filler wire (such as 5356); 5082 wire is supplied for mechanical and forming use rather than as a welding consumable, though it can be used where its composition is acceptable to the procedure.

템퍼 선택 가이드

• O – Soft and formable; for rivets, deep drawing, and complex forming.
• H18 – Medium strength with good spring character; general fasteners and formed parts.
• H38 – Highest strength of the three; structural and high-load wire applications.

주요 특징

Good Strength-to-Weight

Strain-hardened 5082 wire reaches useful tensile strengths while staying light.

내식성

Retains the alloy’s seawater and industrial-atmosphere corrosion resistance.

성형성 및 용접성

O temper forms readily; the alloy welds well with 5xxx fillers where welding is required.

Dimensional Control

Drawn to tight diameter tolerances and supplied on coils or spools for automated feeding.

애플리케이션

• Rivets and structural fasteners
• Automotive and transport body components
• Welded fabricated assemblies
• Industrial wire products and formed parts
• Pressure-vessel and marine fittings

가공 및 표면 마감 참고 사항

• Drawing & straightening: Supplied as coil, spool, or straightened cut lengths.
• 성형: O temper is best for riveting and bending; H tempers need verified bend radii.
• 용접: MIG/TIG with 5xxx filler where the wire is part of a welded assembly.
• Surface: Mill (bright drawn) finish; PVC or paper interleave available for spooled wire.

5082 Aluminum Wire FAQ

What tempers are available for 5082 wire?

Common tempers are O (soft), H18 (medium strength), and H38 (highest strength of the three).

Is 5082 wire the same as 5356 welding wire?

No. 5082 wire is supplied for mechanical and forming use; 5356 is a dedicated welding filler alloy with a different composition. Use the filler specified by your welding procedure.

What diameters can Linsy supply?

Typical diameters are 0.8-12 mm, with tolerances around ±0.05 mm. Other sizes can be quoted on request.

Can 5082 wire be anodized?

It can be anodized, but 5xxx alloys produce a grey tone; powder coating is often preferred for appearance.

일반적인 리드 타임은 얼마인가요?

Typical custom lead time is 10-60 days depending on diameter, temper, and quantity.
