| AWS ERCuNi MIG & TIG Filler Metal Application & uses |
|
The AWS Class ERCuNi MIG and TIG filler metals are copper-nickel alloy, which have been developed as strong and tough with high seawater corrosion resistance. They are generally made up of Copper balance, Nickel 6070, Iron 1.5 2.5, Manganese 0.5 1.5 and traces of Silicon, Carbon, and Sulfur to improve the weldability. Tensile strength is in the range of 380480 Mpa, yield strength is about 120150 Mpa and elongation is 3040, which makes mechanical properties very ductile and very durable. ERCuNi is particularly appropriate in welding copper-nickel alloys so that it can achieve high-quality and corrosion-free joints in marine, offshore, desalination, and heat exchanger applications.

At Ragnar Welding Supplies, we take pride in being one of Indonesia’s trusted suppliers of high-quality welding consumables. Our expertise lies in AWS Class ERCuNi MIG and TIG Filler Metal, engineered for precision, durability, and resistance to corrosion. With a strong commitment to quality and customer satisfaction, we provide welding solutions that support industries across construction, energy, shipbuilding, and manufacturing.
ERCuNi MIG, and TIG filler metals are extensively utilized in welding copper-nickel alloys in all applications that need outstanding corrosion resistance, erosion, and biofouling resistance against sea water. They work perfectly with copper-nickel to either the same or other alloys, making robust and hardy welds in the corrosive sea. Common uses are shipbuilding, offshore structure, desalination plants, heat exchangers, condensers, piping systems and seawater-cooled equipment. ERCuNi filler metals have high levels of corrosion, mechanical strength, and ductility and therefore are used in highly critical marine, chemical processing, and power generation industries where the addition life and reliability is crucial.
