Description

Sifalloy No 79 Copper Nickel TIG Rods (90/10 Cuni) – 3.2 mm x 5 Kg

Sifalloy No 79 Copper Nickel TIG Rods are CuNi alloyed rods designed for joining and surfacing similar alloys with up to 30% nickel content. These rods are copper-nickel-ferrous with 30% nickel, making them particularly suitable for highly stressed corrosion-resistant weld surfacing on cast iron, unalloyed, and low-alloyed steel. Their resistance to seawater makes them ideal for offshore applications, shipbuilding, and other industries requiring corrosion resistance.

Features and Benefits:

  • High Nickel Content: Contains 30% nickel, offering enhanced corrosion resistance.
  • Versatility: Suitable for joining similar copper-nickel alloys and for weld surfacing on various materials.
  • Seawater Resistance: Provides excellent resistance to seawater, making it ideal for marine applications.
  • Optimal Mechanical Properties: Offers an ultimate tensile strength of 420 N/mm² and a hardness of 115 BHN.
  • High Melting Point: With a melting point of 1180°C, it ensures durability and longevity in various applications.

Common Applications:

  • Offshore applications due to its resistance to seawater.
  • Shipbuilding, ensuring the longevity and durability of marine vessels.
  • Plant engineering, especially in areas requiring corrosion-resistant weld surfacing.
  • Chemical and food industry where corrosion resistance is crucial.
  • Oil refineries, ensuring the safety and longevity of equipment.
