The choice of aluminum alloy filler wire is primarily determined by the aluminum base metal being welded. The two most common and versatile aluminum filler wires are ER4043 and ER5356. They are available for both MIG (spools) and TIG (cut-length rods) welding processes.
ER4043 (Aluminum-Silicon) ER4043 is one of the oldest and most widely used aluminum filler wires. It contains 5% silicon, which offers several welding advantages. Characteristics:Weld appearance: Produces aesthetically pleasing, clean, and smooth welds with minimal spatter.Fluidity: The silicon content enhances fluidity, resulting in reduced weld cracking and excellent penetration.Low melting point: The lower melting temperature improves welding characteristics, especially for thinner materials.Weldability: Offers less sensitivity to weld cracking compared to many other aluminum alloys.
Considerations:Welds may turn black after anodizing due to the silicon content.Should not be used for applications requiring maximum ductility.Not recommended for high-magnesium alloys. 
ER5356 (Aluminum-Magnesium) ER5356 is a popular choice for applications requiring higher strength and better corrosion resistance, especially in marine environments. It contains approximately 5% magnesium. 
Characteristics:Strength: The magnesium content provides a weld with a higher tensile and shear strength than ER4043 welds.Corrosion resistance: Offers superior corrosion resistance, particularly when exposed to saltwater.Ductility: Provides higher ductility, which can be important for components that undergo flexing or stress.Anodizing: Unlike ER4043, ER5356 welds match the color of the base metal after anodizing.

ER310 is a fully austenitic stainless steel filler wire primarily used for high-temperature service and joining stainless steels of a similar composition. The weld deposit has excellent resistance to oxidation and scaling at temperatures up to 1200°C.
Key properties:Fully austenitic weld deposit: ER310 produces a fully austenitic weld, which is important for high-temperature applications. However, this also makes it more susceptible to hot cracking, so low heat input is recommended.High-temperature resistance: It offers superior resistance to oxidation and scaling, making it ideal for environments with sustained high heat.Excellent corrosion resistance: The weld deposit has good resistance to a wide range of corrosive chemicals, especially at elevated temperatures.High strength: The weld metal has high tensile and yield strength, providing strong and durable joints.

ER321 is a titanium-stabilized austenitic stainless steel welding wire used for welding type 321, 347, and other similar stainless steel grades. The added titanium prevents the formation of chromium carbides, which can lead to intergranular corrosion. This makes ER321 particularly suited for applications exposed to intermittent high temperatures, typically in the range of 427°C to 816°C (800°F to 1500°F), where the base metal might be susceptible to sensitization.
Common applicationsER321 is ideal for applications requiring resistance to oxidation and corrosion at high temperatures. 

• Aircraft exhaust components: Used for welding exhaust stacks, manifolds, and other engine parts.
• Chemical and petrochemical equipment: Employed in tanks, vessels, and piping systems that operate at elevated temperatures.
• Thermal oxidizers and furnace parts: Used in equipment that requires high-temperature strength and stability.

Stellite filler wires with AWS (American Welding Society) classifications ERCoCr-A, ERCoCr-B, and ERCoCr-C are cobalt-based alloys (commonly known as Stellite 6, Stellite 12, and Stellite 1, respectively) used for hardfacing applications that demand superior resistance to wear, heat, and corrosion. The primary difference among them lies in their carbon and tungsten content, which affects their hardness, impact resistance, and suitability for specific applications.
