Aluminum welding filler metals come in various types, tailored to different aluminum alloys and welding processes. When selecting aluminum filler metals, consider the alloy of the base metal, the welding process, and the requirements for strength, corrosion resistance, and appearance. Each type of filler metal is designed to match or complement the properties of the aluminum alloy being welded.

Common Aluminium Welding Filler Metal​

​

ER5356 Aluminum Welding Filler Metal:

• Composition: Contains aluminum-magnesium (Al-Mg).

• Use: Suitable for welding aluminum alloys like 5086 and 5052.

• Characteristics: Offers good strength and excellent corrosion resistance, particularly in marine environment

ER5183 Aluminum Welding Filler Metal:

• Composition: Contains aluminum-magnesium-silicon (Al-Mg-Si).

• Use: Ideal for welding high-strength aluminum alloys.

• Characteristics: Provides high strength and good resistance to corrosion.

​

Nickel alloy/ Nickel based welding filler metals are used to weld various nickel-based alloys and materials that require high strength, corrosion resistance, or specific properties under extreme conditions. These filler metals are crucial for applications in industries such as aerospace, chemical processing, power generation, and petrochemical.

​Common Nickel Alloy Welding Filler Metal

​

Inconel 625 Welding Filler Metal

• ERNiCrMo-3: This filler metal is used for welding Inconel 625 and similar nickel-chromium-molybdenum alloys. It provides excellent resistance to oxidation, corrosion, and high temperatures. It’s suitable for MIG and TIG welding processes.

Inconel 82 Welding Filler Metal

• ERNiCr-3: This filler metal is used for welding Inconel 600, 601, and 800 series alloys. It offers good strength and oxidation resistance and is typically used with MIG and TIG welding processes.

Inconel 718 Welding Filler Metal

• ERNiFeCr-1: Used for welding Inconel 718, this filler metal provides good mechanical properties and resistance to high-temperature oxidation and corrosion. It’s suitable for both MIG and TIG welding.

Nickel-Iron Cast Iron Welding Electrodes 

• These electrodes contain a significant amount of nickel and iron, which helps to manage the high carbon content in cast iron and improve weldability. They are widely used for repairing cast iron and for welding cast iron to itself or to other metals.

​

Other Common Specialty Welding Filler Metal

​

Stellite 6 (Co6) Welding Filler Metal

• Stellite 6 is one of the most commonly used Stellite alloys, known for its excellent wear resistance and good machinability. It contains cobalt, chromium, and tungsten. It is often used in high-wear and high-temperature applications such as valve seats, turbine components, and cutting tools.

​

ERTi-1, Titanium Welding Filler Metal

• ERTi-1 is the most commonly used filler metal for welding commercially pure titanium (Grade 1, 2, 3, and 4). It is suitable for TIG welding and offers good corrosion resistance and strength.

• Applications: Used for welding titanium and titanium alloys where high purity and strength are required.

​

ERTi-2, Titanium Welding Filler Metal

• ERTi-2 is used for welding titanium alloys such as Grade 5 (Ti-6Al-4V) and Grade 7. It provides good strength and is suitable for applications requiring higher strength and heat resistance.

• Applications: MIG and TIG welding of titanium alloys that require high strength and durability.
