5082-O/H18/H38 铝线

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.

硬度选择指南

• 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.

主要特点

Good Strength-to-Weight

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

耐腐蚀性

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

可成形性与可焊性

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.

应用

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

加工与表面处理说明

• Drawing & straightening: Supplied as coil, spool, or straightened cut lengths.
• 成型： O temper is best for riveting and bending; H tempers need verified bend radii.
• 焊接： 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.

质量文件与检验

Every 5082 wire coil ships with a Mill Test Certificate (MTC) covering chemical composition and mechanical properties. SGS or third-party test reports are available on request. Linsy’s production is managed under ISO 9001, ISO 14001, and ISO 45001 systems.

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.

通常的交货周期是多久？

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

常见订购问题解答

最小起订量是多少？

MOQs depend on diameter and coil format. Smaller stock sizes may have lower MOQs; fully custom sizes are quoted per enquiry.

Do you provide Mill Test Certificates?

Yes. An MTC is supplied with every order, and SGS or third-party inspection reports can be arranged on request.

Which certifications does Linsy hold?

Production is managed under ISO 9001, ISO 14001, and ISO 45001 systems. Material can be supplied to ASTM, EN, GB, and JIS standards on request.

Can you supply cut lengths or spools?

Yes. 5082 wire is available as coil, spool, or straightened cut-to-length pieces.
