NiFe70 Wire

The Crazy Wire Company are best know as suppliers of top quality NiFe70 wire. We have enormous stock levels at all times, as we use this wire to weave our top quality woven mesh products. Our brilliant staff are experts in producing our spools of round wire on our 6 rapid action winding machines. All spools are produced to carry a little extra length to make up for any waste when handling the product.

NiFe70 nickel wire, measuring 0.5mm (24 AWG) in diameter, is a specialised product primarily composed of 70% nickel, combined with iron and other elements. This wire is known for its unique properties, which make it ideal for a variety of applications. As a result of NiFe70’s exceptional corrosion resistance, it is suitable for use in harsh environments where other metals might fail. Because of NiFe70’s corrosion resistance, products and structures made with it last longer. This results in lower maintenance costs and fewer outages.

Nickel wire made from NiFe70 has another significant advantage: its high thermal conductivity. A property like this is essential for applications such as heating systems, thermal sensors, and electronic components where heat distribution is critical. Heat is evenly distributed by the wires in these systems, which contributes to their efficiency and reliability. Furthermore, NiFe70 possesses good electrical conductivity, making it useful in electrical applications that require a steady and consistent current.

Specification of Wire:

  • Diameter – 0.5mm (500 Micron – 24AWG)
  • Ohms/m – 1.048

FAQs About This Wire

What Is NiFe70 Nickel Wire Primarily Used For?

  1. Heating Elements: Due to its high thermal conductivity, NiFe70 is often used in heating systems, including industrial heaters and domestic appliances.
  2. Thermal Sensors and Controls: Its stable response to temperature changes makes it ideal for use in thermal sensors and temperature control devices.
  3. Electrical Applications: NiFe70’s good electrical conductivity makes it suitable for use in electrical components, particularly where stable and consistent current is required.
  4. Electromagnetic Devices: The wire is used in electromagnetic applications, such as in relays, transformers, and magnetic actuators, due to its controlled magnetic responsiveness.
  5. Precision Instruments: Its predictable thermal expansion and corrosion resistance make it ideal for use in precision instruments, ensuring dimensional stability and longevity.

Is NiFe70 Nickel Wire Environmentally Friendly?

Nickel-iron 70 NiFe wire is generally considered to be environmentally friendly due to several key factors. Due to its durability and corrosion resistance, products made with NiFe70 tend to last longer, reducing the need for frequent replacements. The materials in NiFe70 are also highly recyclable, meaning the wire can be reprocessed at the end of its life cycle, which reduces its environmental impact. NiFe70 also has an eco-friendly profile, due to its efficiency in thermal and electrical applications. Nevertheless, NiFe70’s environmental friendliness depends also on the practices involved in its production, use, and disposal. Environmental impact is determined by responsible sourcing and manufacturing practices, as well as proper recycling practices.
