Kobber Nikkelrør C71500
Copper-nickel (also known as cupronickel) alloys offer excellent corrosion resistance to seawater and good fabricability. The addition of nickel to copper improves strength and corrosion resistance while allowing the alloy to remain ductile, other elements can be added to copper-nickel to increase strength, corrosion resistance, hardening, weldability and castability. The nickel-copper alloy has been widely used for r marine applications. C71500 copper alloy, often known as 70/30 copper-nickel, is the alloy with 70% copper and 30% nickel content(as well as C71640), it has higher nickel content than that of C70600 which are more highly alloyed with aluminum, chromium, or tin are used where greater resistance to seawater environments, sand abrasion, wear and galling, as well as higher mechanical properties, are required.
The copper alloy products provide by Tubesolutions shall be fabricated from prime quality raw materials and is fully certifiable to industrial specifications like ASTM and ASME or other relevant standards. Wiho metals mainly supply and stock a large inventory of alloy Copper C71500 (C7150T/CW354H) seamless tubing in accordance with ASTM B466 used for condensers, heat exchangers, Power Steering Tube, Brake Lines applications.

Beskrivelse
Copper Nickel tubes, 30% – C71500 – has, in general, the best resistance of any of the copper alloys to impingement attack and to corrosion from most acids and waters. It is being used in severe corrosive conditions in which service lives longer than those of other copper alloys are desired.
Programmer
The 70-30 copper-nickel alloys have used saltwater and cover thermal desalination, offshore oil and gas, marine shipping, power generation and commercial. Copper-nickel alloys are also used for seawater cooling and firewater systems, hydraulic tubing, heat exchangers, evaporator Tubes and condensers, including brake tubing, platform riser and antimicrobial touch surfaces.
