AWS Class ER 5183 MIG & TIG
ER5183 Aluminium Welding Wire - TIG Filler Rod & MIG Wire Supplier in India
Nicorex Alloys is an ISO 9001 and ISO 14001 certified Mumbai-based supplier and stockist of high-quality ER5183 aluminium welding wire. This specialised filler material is strictly classified under AWS A5.10 and ASME SFA-5.10 industrial standards.
The wire can also be classified as EN ISO 18273 S Al 5183 or UNS A95183. The chemical composition gives a strong wire made of aluminum, magnesium, and manganese, thus making it the strongest Al-Mg filler metal for TIG or MIG welding of 5XXX-series aluminum alloys. ER5183 composition contains 4.3-5.2% Mg and 0.50-1.0% Mn. The Mn content is specified, which gives the alloy significant solid solution strengthening, resulting in a standard tensile strength of 276 MPa (40 ksi) in the as-welded condition. Welding is done under 100% argon shielding in all positions. The main compatible base metals include 5083, 5086, 5454, and 5456 alloys, which are generally used in shipbuilding, cryogenic storage tanks, and offshore construction. The weld metal has superior impact properties down to -196°C and demonstrates superior resistance to seawater corrosion without requiring any heat treatment after welding. Our ER5183 filler metals give the high strength and rust protection you need for tough ocean conditions.
TIG rods are available in diameters ranging from 1.6 mm to 4.0 mm, while MIG spools are provided in sizes from 0.8 mm to 1.6 mm. Every coil and rod ships with a batch-tested Mill Test Certificate (MTC 3.1 per EN 10204) from Nicorex Alloys. As a trader and distributor, we maintain ready stock for quick dispatch across India and for export.

AWS Classification Explained: What Does ER5183 Mean?
Detailed breakdown of the AWS classification system, specifically defining each alphanumeric character within the ER5183 designation for welding applications.
| Designation | Meaning & Technical Significance |
|---|---|
| ER | Electrode / Rod: A solid wire suitable for both MIG (consumable electrode) and TIG (filler rod) welding processes. |
| 5183 | Alloy Chemistry: A high-magnesium (4.3–5.2%) and high-manganese (0.50–1.0%) alloy designed for maximum strength in the 5XXX series. |
ER5183 is the high-strength choice for 5083 aluminium, utilising 0.50-1.0% manganese for superior solid-solution strengthening. It reliably meets code-minimum tensile requirements of 276 MPa (40 ksi), outperforming standard fillers in demanding marine and structural applications.
Chemical Composition of ER5183 Wire per AWS A5.10
The table below presents the precise chemical element limits for ER5183 wire according to the established AWS A5.10 industry standard guidelines.
| Specification | Silicon (Si) | Iron (Fe) | Copper (Cu) | Manganese (Mn) | Magnesium (Mg) | Chromium (Cr) | Zinc (Zn) | Titanium (Ti) | Beryllium (Be) | Aluminium (Al) |
|---|---|---|---|---|---|---|---|---|---|---|
| AWS A5.10 Req. (%) | 0.40 max | 0.40 max | 0.10 max | 0.50–1.0 | 4.3–5.2 | 0.05–0.25 | 0.25 max | 0.15 max | 0.0003 max | Balance |
Mn at 0.50-1.0% is the defining difference versus ER5356 (0.05-0.20%). Combined with Mg at 4.3-5.2%, the Mg + Mn effect exceeds ER5356 in as-welded tensile. Cr at 0.05-0.25% refines grain structure. Cu and Si are held low to minimise hot-cracking sensitivity.
Mechanical Properties of ER5183 Weld Deposits
Summary of typical mechanical properties, including tensile strength and elongation, for deposits created using ER5183 aluminium filler metal.

Industrial Welding Applications of ER5183
The following are the industrial applications of ER5183:
- Marine Structural: Used in high-speed ferries, hull plates, and offshore platforms. It is often the only filler that consistently meets the strict strength requirements set by international maritime agencies for large aluminium vessels.
- Cryogenic Storage: Found in LNG tanks, cold boxes, and liquid nitrogen storage systems. It is chosen for its remarkable ability to stay tough and resist cracking even at extreme freezing temperatures down to -196°C.
- Pressure Vessels: Utilised in the construction of heavy-duty industrial tanks and boilers. It ensures that the welded joints can safely handle the high internal pressures required by international safety standards.
- Naval & Defence: Its superior durability and blast resistance make it the strategic choice for manufacturing high-stakes military hardware.
- Rail Transport: Applied to the car bodies of high-speed trains. It provides the necessary strength to support large, fast-moving structures while keeping the overall weight low for better energy efficiency and speed.
- Aerospace Ground Support: Used in rocket launch pad structures and cryogenic fuel handling systems. It is trusted to hold up under the immense weight and extreme cold of liquid rocket fuels.
Storage and Handling of ER5183 Welding Wire
The ER5183 aluminium filler wire must be stored in its original unopened packaging in a clean, dry location. It should not be exposed to moisture, oil, grease, or hydrocarbons. TIG rods should be handled with clean gloves. Because ER5183 carries higher magnesium, exposed surfaces oxidise faster than lower-Mg fillers. Return partially used MIG spools to protective packaging after each shift.

Frequently Asked Questions
What is the Price of ER5183 Welding Wire per kg in India?
ER5183 is priced higher than ER5356 due to greater manganese content and lower production volumes. Pricing varies with diameter, form, and order quantity. Contact Nicorex Alloys for a current quotation.
Why is ER5183 specified instead of ER5356 for 5083 Structural Welding?
When AWS D1.2 or classification society rules require as-welded tensile matching the 5083 base metal, ER5356 may not often surpass 276 MPa (40 ksi). For added strength, ER5183 has Mn at 0.50-1.0% instead of 0.05-0.20%. For critical maritime structural welds on 5083/5456 that require strength testing, ER5183 is suggested.
Can ER5183 be used for Cryogenic LNG Tank Welding?
Yes. ER5183 on 5083 base metal delivers excellent impact toughness down to -196°C (-320°F). The Al-Mg weld deposit stays ductile without a brittle fracture transition. ASME Section VIII Div. 1 and EN 13458 both permit 5083 welded with ER5183 for cryogenic service.
What is the F-Number for ER5183?
According to ASME Section IX QW-432, aluminium welding employs F-23 filler. There is no A-Number because F-23 has unique qualities that make it a non-ferrous material.
Is ER5183 Suitable for Elevated Temperature Service?
No. Like all Al-Mg fillers with more than 3% magnesium, ER5183 is not suitable for long-term use above 65°C (150°F) because it can develop a beta-phase (Al₃Mg₂) that leads to intergranular corrosion and stress-corrosion cracking. Use ER5554 for elevated-temperature applications.
When should ER5183 not be used?
Avoid using ER5183 for service temperatures exceeding 65°C to prevent stress corrosion cracking. It is also unsuitable for 6XXX series crack-sensitive alloys, cast Al-Si components, or 2XXX series aerospace materials where specialised fillers are required.
