co ni alloy
Silvery copper nickel alloy wire 0.5mm 1mm 1.5mm dia for heating cables in electric blankets
OhmAlloy005(Resistance heating wire and resistance wire)
OhmAlloy005 is a copper-nickel alloy (Cu2Ni98 alloy) with low resistivity for use at temperatures up to 200°C.
Cuprothal 5 is typically used for low-temperature applications such as heating cables in electric blankets and pillows.
The addition of nickel to copper improves strength and corrosion resisitance while allowing the alloy to remain ductile. Other can be added to copper-nickel to increase strength, corrosion resistance, hardening, weldability and castability.
90-10 copper-nickel (C70600, CW352H), an alloy with 90% copper and 10% nickel, is the most commonly used alloy. It can be found in naval and commercial shipping, offshore oil and gas production as well as desalination and power generation. Alloys with 30% nickel content (C71500, C71640) and those which are more highly alloyed with aluminum, chromium or tin are used where greater resistance to seawater flow, sand abrasion, wear and galling, as well as higher mechanical properties, are required.
