ESAB 181512242 3/64″, OK Alloy Solid Mig Wire

The ESAB 181512242 OK Alloy Solid MIG Wire is a 3/64″ (1.2mm) ER5356 aluminum welding wire, widely recognized as a general-purpose filler metal for welding 5XXX series aluminum alloys. Known for its high shear strength, this non-heat-treatable alloy is often selected for marine, automotive, and structural aluminum applications. With a tensile strength of 38 ksi (265 MPa) and an elongation of 26%, it delivers strong, ductile welds that withstand demanding conditions.

This wire is best suited for DC(+) welding applications and is commonly used in aluminum fabrication requiring high-strength welds. However, it should be noted that 5XXX series aluminum alloys containing more than 3% magnesium, when welded with ER5356 and exposed to service temperatures exceeding 65°C, may be susceptible to stress corrosion cracking.

Features:

• ER5356 Aluminum Alloy: A high-strength, general-purpose filler metal for aluminum welding.
• Excellent Shear Strength: Provides durable, long-lasting welds, even in high-stress applications.
• Non-Heat Treatable: Delivers consistent mechanical properties without the need for post-weld heat treatment.
• Good Corrosion Resistance: Suitable for marine and outdoor applications where exposure to moisture is common.
• High Ductility: With 26% elongation, it allows for thermal expansion and contraction without cracking.
• 20 lb Spool: Offers extended welding time, reducing downtime for spool changes.

Markets:

• Marine & Shipbuilding: Commonly used for boat hulls, docks, and offshore aluminum structures.
• Automotive Manufacturing & Repair: Ideal for welding aluminum body panels, frames, and structural components.
• Aerospace Fabrication: Used for aircraft components requiring lightweight, high-strength welds.
• Structural Aluminum Fabrication: Suitable for bridges, railings, and other load-bearing aluminum structures.
• Trailer & Truck Manufacturing: Ensures secure, durable welds in aluminum truck bodies and trailers.
• General Welding Shops: A preferred choice for fabricators handling various aluminum welding projects.
