Mn25 - wire, circle, sheet, tape

Mn25 - wire, circle, sheet, tape

AvekGlob company sells wire, circle, sheet and tape, which are made of copper-nickel alloy of MN25 brand (other names and analogues — 2.0830, CuNi25) at reasonable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Composition and application

Copper-nickel alloy grade MN25 is very good resistance to biological fouling and marine corrosion, and also very technological in production. The presence of nickel provides this alloy with increased strength and corrosion resistance up to temperatures of 250 ° C.

Because of the low electrical conductivity, MH25 is mainly used as resistance alloys. It is also distinguished by its high corrosion resistance, good weldability and its suitability for lining other materials. Therefore, in construction and architecture, MH25 alloy products are used as base layers on welded seams and welding profiles (welded bands).

The area of rational use of products made from this alloy is fish cells used for aquaculture, external fire-extinguishing systems, heat exchangers and condensers, hydraulic lines, shells of legs, supports and risers on boat hulls and offshore platforms, pipelines for pumping seawater, parts of desalination plants .

The chemical alloy of the alloy, which meets the technical requirements of GOST 492−2006, is presented in the table (numerical data — in percent, copper — the rest):

Ni + Co
Fe C Mn S Pb Zn Impurities
24… 26 Not more than 0.5 Not more than 0.05 Not more than 0.5 Not more than 0.01 Not more than 0.005 Not more than 0.3 only 1.3
