SIF Sifalloy No.73 Copper Nickel TIG Filler Rods - 70/30 CuNi - 3.2mm Dia. - 5kg

Sifalloy No 73 Copper Nickel TIG Rods are copper-nickel-ferrous rods containing 30% nickel. They are designed for welding applications that require high resistance to corrosion, especially in marine environments. These rods are particularly suitable for surfacing on cast iron, unalloyed, and low-alloyed steel, making them versatile for various industrial applications.

Features and Benefits

• High Nickel Content: Contains 30% nickel, providing enhanced corrosion resistance.
• Seawater Resistance: Offers protection against the corrosive effects of seawater, making it ideal for marine applications.
• Versatility: Suitable for weld surfacing on various materials, including grey cast iron, unalloyed steel, and low-alloyed steel.
• Industry Applications: Due to its resistance to seawater, it’s ideal for offshore, shipbuilding, chemical, food industry, and oil refineries.

Common Applications

• Offshore Applications: Due to its resistance to seawater.
• Ship Building: Provides durability and resistance in marine constructions.
• Chemical Industry: For equipment and structures exposed to corrosive chemicals.
• Food Industry: Suitable for equipment and structures that come in contact with food products.
• Oil Refineries: For structures and equipment exposed to crude oil and its by-products.

Welding Positions

Due to the resistance to sea water the alloy is suitable for offshore applications, ship building, chemical and food industry and oil refineries.

Material to be Welded

Particularly suitable for highly stressed corrosion-resistant weld surfacing on grey cast iron and on unalloyed and low-alloyed steel.
