Product DescriptionProduct DescriptionINTRODUCTION TO SILICON BRONZE WELDING ALLOYS(C65500,C65600,ERCUSI-A, AWS A5.7, ASME-5.7)ERCuSi-A is a copper-silicon alloy widely used as a welding filler metal due to its superior properties, including excellent weldability, corrosion resistance, and mechanical strength. It is primarily used in MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding processes for joining a variety of metals such as copper, brass, bronze, and steel. ERCuSi-A is designated under AWS A5.7 and ASME SFA-5.7 standards, and is known for its excellent fusion properties, making it ideal for high-performance applications.CHEMICAL COMPOSITIONS(%)CuSILICON(SI)Manganese(Mn)Tin(Sn)Iron(Fe)Zinc(Zn)Balance2.8-4.0%1.5%(max)1%(max)1.0-2.01%(max)KEY CHARACTERISTICSGood weldability / filler compatibilityBecause the alloy is designed for welding of copper, silicon bronze, and galvanized steel/steel to copper/bronze, it offers good fluidity in the weld pool, good wetting behaviour on copper and copper alloys, and compatibly matches base metals of similar systems. For example: "Use for welding of silicon bronze copper, or aluminum bronze of low aluminum content. It can also be used for brazing malleable iron and light gauge steel.Mechanical strength and ductilityThe deposited weld metal has tensile strength on the order of ~345 MPa and good elongation (~40%). That means the filler provides a reasonably ductile joint, which is beneficial when joining materials of different metallurgical and thermal expansion characteristics. The presence of about 3 % Si and small Mn helps strengthen the copper matrixCorrosion and wear resistanceSilicon bronze alloys (with Si addition) are known for improved corrosion resistance, particularly in environments where copper alloys are exposed. The addition of Mn may improve mechanical properties and wear resistance. For example: "It is a silicon bronze welding wire containing 3% silicon and a small amount of manganese … the addition of manganese enables it to have good mechanical properties, good corrosion resistance and good wear resistance after welding."Thermal / metallurgical behaviourBecause the silicon content is moderate and aluminum content is very low, the alloy avoids some of the issues of high-aluminium bronzes (e.g., rapid oxidation, phase transformations).Color match Golden bronze color matching copper and copper alloys-ideal for visible or decorative jointsTYPICAL APPLICATIONSWelding of copper, bronze, and brass to steel or themselvesUsed for welding copper and copper-silicon/brass alloys to themselves or to steel/iron. Example: "MIG and TIG and oxyacetylene welding of copper, copper-silicon, and copper-zinc metals to themselves and to steel.Also used for welding galvanized steel / coated sheet steels (brass weld of coated steel). From one datasheet: "Frequently used to 'brass weld' coated sheet steels. Sometimes used to weld galvanized steels.Architectural and Decorative:ERCuSi-A is often used in architectural bronze applications for stair railings, door handles, and ornamental finishes, where its corrosion resistance and color are prized.Brazing / repair of copper/bronze componentsThe filler alloy can function in brazing or "braze-welding" (low melting) contexts for copper/bronze components, particularly thinner or coated sheet steels. Example: "It can also be used for brazing malleable iron and light gauge steel." Repair welding of copper alloy castings, bronze sculptures, or copper piping may use this filler when the base alloy is compatible.Marine, architectural, artistic, and electrical applicationsCopper bronze filler applications where aesthetics, corrosion resistance (especially in exposed or marine environments) matter.Joining copper busbars, switchgear, or other electrical connectors where copper alloy filler is appropriate. The datasheets mention switch-cabinet, solenoid valve, motorcycle parts, etcMarine IndustryWelding of bronze and brass parts exposed to saltwater environments, such as boat fittings, propellers, and marine hardware.Automotive and AerospaceUsed in the repair and manufacture of components where high-strength, corrosion-resistant alloys are required, such as heat exchangers, valve seats, and brake components.PRODUCT IMAGES AND FACILITIESCompany ProfileRich Base Technology Co., LimitedYour Trusted Partner in Copper Alloy Materials!Founded in 2007, Rich Base Technology Co., Limited is one of the leading manufacturers of copper alloy materials in China.
