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.

Style of supply
Copper-nickel (also known as cupronickel) alloys are widely used for marine
applications due to their excellent resistance to seawater
corrosion, low macrofouling rates, and good fabricability They have
provided reliable service for decades while offering effective
solutions to today’s technological challenges.
