Low Temperature Coefficient Of Resistivity Wire Alloy 60/ CuNi6
Round / Ribbon Shape 0.15mm 0.3*4mm For Heating Mats
Product Description:
Copper nickel alloy wire is a type of wire made from an alloy that combines copper and
nickel, and sometimes also contains other elements. The nickel
content in the most common copper nickel alloys is typically in the
range of 10% to 30%.
This kind of wire offers a balance of properties. It combines the
excellent corrosion resistance of copper with the added strength
and durability provided by nickel. It has excellent electrical
conductivity, thermal stability, and durability. Copper nickel
alloy wire is widely used in various industries, such as electrical
and electronic applications (e.g., in making thermocouples,
resistors, and heating elements), the aerospace industry,
telecommunications, and marine and offshore applications. It can
also be used in the production of aerial cables, overhead insulated
cables, and aerial bundled cables.
CuNi6 is often known as copper - nickel alloy 6 or cupronickel 6.
In some contexts, it might also be referred to simply as a 94 - 6
copper - nickel alloy (since it's approximately 94% copper and 6%
nickel).
CuNi6 alloy wire is also known as "Cu Prothal 10" and "NC 6" in addition
to being called CuNi6. These are some of the other common names for
this alloy wire.

Advantages of CuNi6 alloy wire compared to other resistance wire
materials:
- Good mechanical properties:
- High tensile strength: It can withstand relatively high mechanical
stress without easy breakage or deformation, which is important for
applications where the wire may be subjected to tension, bending,
or other mechanical forces. This makes it suitable for use in
environments where the wire needs to maintain its structural
integrity, such as in some industrial heating elements or
electrical equipment that may experience vibration or movement.
- Good bending proof performance: It can be bent to a certain extent
without significant damage to the wire, allowing for easier
installation and shaping in various applications.
- Resistance characteristics:
- Higher resistance than copper: Compared to pure copper wire, CuNi6
alloy wire has a higher resistivity, which means it can generate
more heat per unit of current passing through it. This makes it an
efficient material for use in resistance heating applications, as
less wire is needed to achieve the desired heating effect, saving
space and material costs.
- Temperature stability:
- High temperature resistance: It can operate at relatively high
temperatures up to 220 °C without significant degradation in its
properties. This is beneficial for applications that require the
wire to function in high-temperature environments, such as in some
industrial heating processes or high-temperature electrical
equipment.
- Low temperature coefficient of resistivity: The change in
resistance of CuNi6 alloy wire with temperature is relatively small
compared to some other materials. This ensures a more stable
electrical performance over a wide range of temperatures, which is
important for applications where accurate resistance control is
required.
- Corrosion resistance:
- Good resistance in certain environments: In normal atmospheric
conditions at 20 °C, CuNi6 alloy wire has good corrosion
resistance. It is also resistant to oxidation, which helps to
maintain the wire's performance and lifespan over time. This is
particularly important for applications where the wire may be
exposed to air, moisture, or other corrosive substances.
- Non-magnetic property:
- No interference with magnetic fields: In some applications where
magnetic fields may be present, such as in certain electronic
devices or near magnetic sensors, the non-magnetic property of
CuNi6 alloy wire is an advantage. It ensures that the wire does not
interact with the magnetic field and cause interference or errors
in the operation of the device.
