Marsh Nickel Alloys, located in Canberra, Australia, is a well-known manufacturer and supplier of premium metal alloys used in marine, engineering, and industrial projects. Among their trusted products is the Copper Nickel Coil, valued for its superior corrosion resistance and excellent thermal stability. The company uses modern technology and strict quality control to produce coils that perform reliably even in demanding environments like seawater or chemical plants. With a strong reputation for delivering consistent quality and customer satisfaction, Marsh Nickel Alloys continues to be a preferred source for high-performance alloy solutions across Australia and beyond.
Copper Nickel Coil is primarily made of copper with 10–30% nickel, depending on the grade. It often includes small additions of iron and manganese to enhance strength and resistance to seawater corrosion. This alloy provides good mechanical strength, ductility, and excellent thermal and electrical conductivity. Typical tensile strength ranges between 300–500 MPa, and it remains stable under high temperatures. Its smooth surface and formability make it easy to bend and shape, making Copper Nickel Coil a durable and dependable material for both industrial and marine applications.

Copper Nickel Coils are widely used in marine engineering, especially for heat exchangers, condensers, and seawater piping systems, because of their excellent resistance to saltwater corrosion. In power plants and desalination systems, they are used for cooling tubes and evaporator coils. The alloy’s good thermal conductivity also makes it useful in HVAC units, chemical processing equipment, and shipbuilding. Due to its non-magnetic and anti-biofouling properties, it helps prevent marine organism growth on underwater structures. Copper Nickel Coils are also used in automotive brake systems and coin manufacturing for their strength, conductivity, and long-lasting performance.
