53563645 - Nexalloy ER5356 Aluminum MIG Wire - 0.045 Inch - 5 lb Spool

Smooth Feeding and Strong Welds with Nexalloy 5356

If you have ever struggled with "birdnesting" while trying to push soft aluminum wire through a MIG torch, you will appreciate the difference with Nexalloy ER5356. This 5356 alloy is naturally stiffer than the common 4043 wire, giving it higher column strength. This stiffness allows it to feed much more reliably through standard MIG gun liners and push-pull systems, reducing downtime caused by wire jams and liner clogging. For welders using a spool gun, the 5 lb spool configuration is the perfect balance of weight and capacity, allowing for extended welding time on boat trailers, truck beds, or architectural frames without the frequent change-outs of 1 lb spools.

Nexalloy 5356 is the go-to wire when structural integrity is paramount. It produces a weld deposit with higher tensile strength and ductility than 4043, making it the superior choice for parts subject to vibration or shock loading. It flows wet and fast, but you will notice it has a slightly different fluidity compared to silicon alloys; it freezes a bit faster, which is excellent for out-of-position welding (vertical up or overhead). The bead profile is typically convex with distinct ripple patterns, and when cleaned properly, it leaves a bright, professional finish.

This wire is specifically formulated to combat the common headaches of aluminum welding. The surface is shaved and cleaned during manufacturing to minimize aluminum oxide shavings that can clog your liner or gun tip. Whether you are fabricating a custom aluminum bumper, repairing a pontoon boat, or welding 6061 structural tubing, this 0.045" wire provides the penetration and fill you need. Remember to use 100% Argon gas and ensure your base metal is cleaned with a stainless steel brush before striking an arc to prevent porosity.

Best Practices for Setup

• Drive Rolls: Always use U-groove drive rolls designed for aluminum to prevent deforming the wire.
• Liner: Use a Teflon or plastic liner to reduce friction and prevent wire shaving.
• Contact Tip: Use a tip sized specifically for aluminum (often marked with an 'A') which allows for thermal expansion.
• Brake Tension: Set the spool brake tension as loose as possible without the wire unraveling to minimize drag.
