5019 aluminum wire is a high-magnesium (AlMg5), non-heat-treatable 5xxx series alloy wire supplied in O, H14, and H18 tempers. With approximately 5% magnesium content, it combines high strength, excellent ductility, and outstanding resistance to seawater and industrial chemicals. Available in diameters from 0.8 mm to 30 mm, it is widely used as welding filler wire for 5083, 5086, and 5456 alloys, as well as for marine rivets, fasteners, and structural components. Linsy supplies 5019 wire in coil or straightened cut lengths with custom dimensions, low MOQ, and MTC documentation for every order.

5019 aluminum wire is a high-magnesium, non-heat-treatable alloy wire belonging to the 5xxx series (Al-Mg). Designated as EN AW-5019 in the European standard and approximately equivalent to AA 5056 in the US Aluminum Association system, it contains approximately 5% magnesium (AlMg5) along with small amounts of manganese and chromium. The alloy is supplied in O (annealed), H14 (half-hard), and H18 (full-hard) tempers.
5019 wire is valued for its combination of strength, ductility, and outstanding corrosion resistance, particularly in seawater and industrial chemical environments. It is widely used as welding filler wire for 5xxx series structural alloys and as rivet wire in marine and heavy-duty applications.
As a non-heat-treatable alloy, 5019 achieves its mechanical properties through strain hardening (cold working). The O temper provides maximum ductility for forming and welding applications, while H14 and H18 tempers offer increased strength for mechanical fasteners and structural components.
Linsy supplies 5019 aluminum wire in three tempers, covering diameters from 0.8 mm to 30 mm. Wire is available in coil form (minimum 50 kg per coil) or as straightened cut lengths, with custom dimensions available on request.
Soft and highly ductile, 5019-O wire is the standard choice for welding filler wire and forming applications. Its low yield strength allows smooth feeding and consistent deposition in MIG and TIG welding processes.
Offering a balance of strength and formability, 5019-H14 wire is used in general fabrication where moderate forming is required but higher strength than the O temper is needed.
The highest strength in the 5019 wire range, H18 temper is used for rivets, fasteners, and spring applications where tensile strength and hardness are critical.

Choosing the correct temper for 5019 aluminum wire depends on the intended application and required balance of strength, ductility, and formability:
For welding filler wire applications, O temper is the industry standard. For rivet and fastener manufacturing, H18 is typically specified. If you are unsure which temper suits your application, contact Linsy’s technical team with your requirements for guidance.
5019 aluminum offers excellent resistance to seawater, marine atmospheres, and a wide range of industrial chemicals. The high magnesium content forms a stable protective oxide layer that resists pitting and general corrosion in chloride environments, making it a standard choice for marine welding and fastener applications.
5019 wire is primarily used as a welding filler metal for 5xxx series structural alloys. It provides good arc stability, smooth bead appearance, and sound weld metal with 5083, 5086, and 5456 parent metals. As a filler wire, it is classified under AWS A5.10 (bare aluminum welding electrodes and rods).
With approximately 5% magnesium, 5019 delivers higher tensile strength than pure aluminum and 3xxx series alloys while maintaining relatively low density. In H18 temper, it achieves tensile strengths up to 420 MPa, comparable to some heat-treatable alloys, but without the need for solution heat treatment.
As a non-heat-treatable alloy, 5019 gains strength through cold working (strain hardening) rather than precipitation hardening. This means its properties are stable after forming and do not change with subsequent heating at moderate temperatures, simplifying fabrication and post-weld performance.
In the O temper, 5019 wire exhibits excellent formability and can be readily bent, headed, and formed. As temper increases to H14 and H18, formability decreases while strength increases. The alloy work-hardens during cold forming, which should be considered in tooling and process design.
5019 aluminum wire is used across marine, industrial, and structural applications where corrosion resistance and moderate-to-high strength are required:
5019 aluminum wire is produced through cold drawing from rod stock, followed by annealing or strain hardening to achieve the specified temper. The following processing and surface finish considerations apply:

5019 is the European designation (EN AW-5019) and 5056 is the US Aluminum Association designation. They share nearly identical chemical composition (AlMg5) and are generally treated as equivalent in practice. Minor specification differences may exist between EN and ASTM standards; confirm with your engineering requirements when substituting one for the other.
O (annealed) temper is the standard choice for welding filler wire. Its softness allows smooth feeding through MIG/TIG welding equipment and consistent arc performance. H14 and H18 tempers are typically used for mechanical applications such as rivets and fasteners, not for welding filler.
5019 filler wire is primarily recommended for welding 5xxx series alloys such as 5083, 5086, and 5456. For 6xxx series welding, 4043 or 4047 (Al-Si) filler is generally preferred. Consult your welding procedure specification (WPS) and qualified welding engineer for the correct filler selection for your specific application.
Standard diameters range from 0.8 mm to 30 mm. Common welding wire diameters include 1.2 mm, 1.6 mm, 2.0 mm, 2.4 mm, and 3.2 mm. Custom diameters within the 0.8–30 mm range are available on request.
Yes. With approximately 5% magnesium content, 5019 offers excellent resistance to seawater and marine atmospheres. It is a standard choice for marine welding filler and for rivets and fasteners used in boat hulls, deck fittings, and offshore structures.
