Uses of ERCuAl-A2 Wire
The ERCuAl-A2 filler metal, which contains iron-bearing aluminum bronze, is typically employed for welding:
- Aluminum bronzes with similar compositions,
- Manganese bronze,
- Silicon bronze, and
- Certain copper-nickel alloys, ferrous metals, and
- Dissimilar metals.
One of the more prevalent combinations of dissimilar metals involves joining aluminum bronze to steel and copper to steel.
This particular alloy is also utilized for its ability to form surfaces that are resistant to both wear and corrosion.
ERCuAl-A2 TIG Rod
ERCuAl-A2 TIG (Tungsten Inert Gas) rod is a type of welding rod used in TIG welding to join aluminum bronze alloys. It is a copper-based alloy that contains aluminum and iron, as well as small amounts of nickel and manganese.
The TIG welding process involves melting the welding rod and the base metal together using a non-consumable tungsten electrode, while a shielding gas (usually argon or helium) is used to protect the molten metal from atmospheric contamination.
ERCuAl-A2 TIG rod is commonly used in applications where high strength and corrosion resistance are required, such as marine components, heat exchangers, and other non-ferrous metal components. It is also used in the repair of aluminum bronze components.

ERCuAl-A2 TIG rod is available in standard 1-meter lengths and in sizes of 0.035, 0.45, 1/16, 3/32 and 1/8 inches.
TIG welding using ERCuAl-A2 tig rod is carried out using 100% argon or a mix of argon 75% + helium 25%.
ERCuAl-A2 MIG wire
ERCuAl-A2 MIG (Metal Inert Gas) wire is a type of welding wire used in MIG welding to join aluminum bronze alloys.
It is a copper-based alloy that contains aluminum and iron, as well as small amounts of nickel and manganese.
The MIG welding process involves feeding the welding wire continuously into the welding pool while a shielding gas (usually argon or a mix of argon and helium) is used to protect the molten metal from atmospheric contamination.
ERCuAl-A2 MIG wire is commonly used in applications where high strength and corrosion resistance are required, such as marine components, heat exchangers, and other non-ferrous metal components. It is also used in the repair of aluminum bronze components.
The wire is manufactured according to the AWS A5.7 specification and is available in wire spool form in sizes of 0.035, 0.45, 1/16, 3/32, and 1/8 inches.
