Santner Nickel Alloys is a reputable manufacturer and supplier located in Hamilton, New Zealand, focusing on high-performance welding materials designed for tough industrial applications. With a strong commitment to quality, precision, and reliability, the company delivers advanced solutions specifically tailored for the marine, chemical, and power generation industries. One of their standout products is the AWS Class ECuNi Coated Electrodes, which are renowned for their exceptional corrosion resistance and mechanical stability. Thanks to modern manufacturing techniques and rigorous quality control, Santner Nickel Alloys guarantees consistent performance and long-lasting weld integrity, making them a go-to choice for industries that need reliable nickel-based welding consumables.
The AWS Class ECuNi Coated Electrodes are made from a copper-nickel alloy that typically contains about 65% copper and 30% nickel, with carefully controlled amounts of iron and manganese to boost strength and corrosion resistance. These electrodes boast impressive mechanical properties, including high tensile strength, excellent ductility, and robust impact resistance, even in challenging marine and brackish environments. The weld metal shows remarkable resistance to seawater corrosion, stress cracking, and biofouling. With their stable arc, smooth bead appearance, and minimal spatter, they are perfect for high-quality, durable welding applications.
