What Is 5005 Aluminum Alloy?

5005 aluminum alloy (UNS A95005) is a non-heat-treatable 5000 series aluminum alloy primarily alloyed with magnesium (0.5–1.1%). Unlike 6000 or 7000 series alloys, 5005 cannot be strengthened by heat treatment; instead, it is strengthened through strain hardening (cold working) to achieve tempers such as H32, H34, H36, and H38. This composition gives 5005 its characteristic combination of good corrosion resistance (especially in atmospheric and marine environments), moderate strength, excellent formability, and — most notably — an anodizing response that produces a bright, uniform finish closely matching the appearance of pure aluminum.

5005 is commonly specified for architectural and decorative applications where appearance after anodizing is critical. It is also used in electrical busbars, marine fittings, signage, and general fabrication where weldability and corrosion resistance matter more than high strength. The alloy is supplied in nearly every product form, and Linsy can source or process 5005 in sheet, coil, plate, bar, tube, wire, and custom profiles to meet project-specific requirements.

Руководство по выбору температуры

5005 is strain-hardenable and not heat-treatable. Selecting the right temper depends on the balance you need between strength, formability, and weldability.

Темпер	Основное преимущество	Лучшее для
O (отожженный)	Maximum formability and lowest strength	Deep drawing, spinning, parts requiring extensive forming before welding
H32 / H34	Good strength with reasonable formability	General fabrication, welded assemblies, architectural panels, signage
H36 / H38	Higher strength, reduced formability	Trim components, decorative parts, applications with minimal forming

For most architectural and anodized applications, H32 or H34 tempers are preferred. O temper is recommended when extensive forming is required before final assembly.

Key Characteristics of 5005 Aluminum

Устойчивость к коррозии

5005 aluminum offers excellent resistance to atmospheric corrosion, including industrial and coastal environments. It performs well in marine atmospheres, though for continuous seawater immersion, 5000 series alloys with higher magnesium content (such as 5083 or 5086) are typically preferred. For architectural and general marine fittings, 5005 provides more than adequate corrosion resistance.

Anodizing Response

One of the most valued characteristics of 5005 aluminum is its anodizing response. When anodized, 5005 develops a clear, bright finish that closely matches the appearance of pure aluminum, making it the preferred choice for architectural anodized applications where color consistency and brightness are important. It is commonly used for building facades, decorative trims, and signage that require anodized surface treatment.

Formability & Weldability

5005 has good formability in O and H32/H34 tempers, making it suitable for bending, drawing, and spinning operations. It can be welded using standard TIG and MIG processes; however, weld filler selection should consider the specific application. O temper material is preferred for weldments that will see significant forming after welding. Like other aluminum-magnesium alloys, welding does not require pre- or post-heat treatment.

Примечания по обработке и отделке поверхности

5005 aluminum is well-suited to a range of fabrication and finishing processes. The following notes are provided to support procurement and fabrication planning.

• Machining: 5005 has fair machinability in strain-hardened tempers and better machinability in O temper. It is not as free-machining as 2011 or 6262, but standard aluminum machining practices apply.
• Сварка: 5005 is readily weldable using TIG and MIG processes. Filler wire selection should match the base alloy or be selected per welding procedure specifications. No heat treatment is required before or after welding.
• Анодирование: 5005 produces a bright, clear anodized layer that closely matches pure aluminum in appearance. It is the preferred alloy for architectural anodizing where a consistent, attractive finish is required. Discuss finish specifications (thickness, sealing, color) with our technical team when ordering.
• Surface finishing: In addition to anodizing, 5005 accepts polishing, brushing, and chemical conversion coatings. Painted or powder-coated finishes also adhere well with proper pretreatment.
• Forming: O and H32 tempers offer the best formability. Sharp bends should consider the minimum bend radius per temper and thickness; consult our technical team for forming guidelines.

5005 Aluminum FAQ

What is 5005 aluminum alloy used for?
5005 is primarily used in architectural anodized applications, signage, decorative trims, building facades, marine fittings, and electrical busbars. Its excellent anodizing response makes it the preferred choice where appearance after anodizing is important.

Is 5005 aluminum heat-treatable?
No. 5005 is a non-heat-treatable aluminum-magnesium alloy. It is strengthened through cold working (strain hardening) to achieve H32, H34, H36, H38, and other tempers. It cannot be solution-heat-treated and aged like 6000 or 7000 series alloys.

What is the difference between 5005 H32 and H34?
H32 is strain-hardened and partially annealed to achieve about half the strength of a full-hard H38 temper, offering better formability. H34 is strain-hardened and partially annealed to about three-quarters of the full-hard strength, offering higher strength with moderate formability. For most architectural and formed parts, H32 or H34 are the preferred tempers.

Can 5005 aluminum be welded?
Yes. 5005 is readily weldable using TIG and MIG processes. No heat treatment is required. Filler wire selection should be appropriate for the application; consult our technical team or your welding procedure specification.

Does 5005 anodize well?
Yes. 5005 is one of the best aluminum alloys for architectural anodizing. It produces a bright, clear anodized finish that closely matches the appearance of pure aluminum. It is widely specified for building facades, signage, and decorative architectural parts that require anodized surface treatment.

What sizes are available for 5005 aluminum sheet and plate?
Linsy supplies 5005 sheet in thicknesses from 0.3 mm to 6.0 mm, and plate from 6.0 mm to 80 mm. Widths up to 2600 mm and lengths up to 16000 mm are available, with custom sizes offered on request.

Is a material test certificate (MTC) provided?
