Round, wire, pipe CuNi30 - Alloy 24 - C71500

Do you want to buy a circle, wire, a tube of CuNi30 alloy (Alloy 24, C71500) from a supplier — AvecGlob Company? Here you will find the necessary information on this topic

Buy at affordable prices from the manufacturer of a volume rolling (circle, wire or pipe), made of copper-nickel alloy grade CuNi30 (other names — Alloy 24, C71500), offers the company AvekGlob. The supplier ensures the timely delivery of products to any address specified by the consumer.

Composition and application

Copper alloy CuNi30 (Alloy 24, C71500) is characterized by moderate strength, workability, ductility and weldability. In North America, the composition and properties of this alloy are regulated by the requirements of ASTM B466 and ASME SB466 standards.

The alloy finds the greatest application in areas where an optimal combination of high temperatures and mechanical pressures is required with a high rate of movement of liquid (or gaseous) working media with appreciable flow turbulence. The low iron content, up to 0.5%, gives the alloy CuNi30 (Alloy 24, C71500) a sufficiently high resistance to corrosion, as well as to stress corrosion cracking, which makes it very suitable for use in marine applications or in various chemical, medical or the food industry. Most often, from the alloy under consideration, pipes of heat exchangers, pipelines for pumping chlorine-containing media, heat exchanger housings, etc. are produced. The recommended application temperature at which the alloy does not lose its corrosion resistance is 350… 370 0 С.

The chemical composition of CuNi30 alloy (Alloy 24, C71500) is given in the table:

Cu Pb Zn Fe Ni Mn  

The minimum percentage


- - - 0.40 29.0 -  

The maximum percentage


The basis 0.05 1.0 1.0 33.0 1.0  

Notes. 1. The chemical purity of copper should not be less than 99.5%, while in the composition of copper there may be some silver. 2. The table shows the total percentage of nickel together with cobalt.

AvekGlO sells wire, pipe and a circle of copper-nickel alloy CuNi30 (Alloy 24, C71500) at economically advantageous prices. The supplier provides a guaranteed sending of bulk rolled metal to any point set by the customer.
