Adrian Nickel Alloys stands out as a top-notch manufacturer and supplier of high-quality copper-nickel products right in Singapore, Pulau Ujong. They take pride in offering premium Copper Nickel 70/30 coils, which are celebrated for their remarkable corrosion resistance, durability, and thermal performance. These coils are specifically designed to meet the demands of marine, chemical, and industrial applications, ensuring consistent quality and dependable performance. By blending advanced manufacturing techniques with rigorous quality control, Adrian Nickel Alloys guarantees that their Copper Nickel 70/30 coils adhere to strict industry standards, making them a perfect fit for piping, heat exchangers, and condensers in environments that face seawater, chemicals, and other corrosive elements.
The Copper Nickel 70/30 coils are made up of about 70% copper and 30% nickel, often with trace amounts of iron and manganese to enhance strength and corrosion resistance. This alloy is known for its outstanding resistance to seawater erosion, pitting, and biofouling, all while maintaining good thermal conductivity and ductility. On the mechanical side, it boasts a tensile strength of around 350–450 MPa and an elongation of 25–35%, making it easy to form, bend, and fabricate without the risk of cracking. Its unique blend of corrosion resistance and mechanical strength ensures it performs reliably in tough environments.
