ERCuSi-A is a specific classification for silicon bronze welding filler metal (wire or rod) used in TIG and MIG welding and brazing. It is known for its excellent corrosion resistance and the ability to join various metals, including copper alloys and steel.
Key Characteristics
Material Composition: It is a copper-based alloy containing approximately 2.8% to 4.0% silicon, with small amounts of manganese, tin, or zinc.
AWS Classification: The "ER" indicates it can be used as an electrode or a rod, while "CuSi-A" refers to the specific chemical composition as defined by American Welding Society (AWS) A5.7 standards.
Properties: Welds produced with ERCuSi-A have good mechanical properties, high electrical conductivity, and a visually appealing bronze or gold color, which makes it popular for artistic and marine applications.
Melting Point: It has a relatively low melting point of approximately 1,866°F (1,019°C), which helps minimize heat distortion of the base metals during welding.
Primary Applications
ERCuSi-A is a versatile filler metal used for a variety of tasks:
Joining Copper Alloys: Welding copper, copper-silicon, and copper-zinc base metals to themselves.
Joining Dissimilar Metals: Effectively joining copper alloys to steel, galvanized steel, and cast iron.
MIG Brazing: Widely used for MIG brazing galvanized steel sheets, such as automobile door frames, as the lower heat input preserves the galvanized coating.
Surfacing: Used for overlay welding on areas subject to corrosion or wear, such as friction surfaces on machinery
