Ni80 Heat Wire
The Crazy Wire Company are well known as suppliers of top quality Ni80 high heat wire. We have enormous stock levels at all times, as we use this wire to weave our high specification 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.
The 0.42mm (26 AWG) Ni80 nichrome heat wire is a high-quality, versatile wire designed for a broad range of applications. Nickel and chromium are combined in this wire to provide durability and excellent heat resistance. The quick heating properties of this material make it an ideal material for electrical heating elements found in domestic appliances such as toasters and ovens. The material’s consistency and resilience makes it suitable for use in furnaces and ceramic processing tools. It provides longevity and reliability due to its uniform diameter and resistance to oxidation at high temperatures. Artists and hobbyists benefit from its malleability in craft projects, and scientists value its consistent resistance properties in experiments. Ni80 nichrome heat wire is an excellent choice for industrial and household heating applications.

FAQs About This Wire
What Is The Best Heat Wire?
The “best” heat wire depends on the specific application and requirements. Some of the factors that need to be considered include:
- Operating temperature: Choose a wire with a high melting point and maximum operating temperature for high temperature applications.
- Resistance: The wire should have a suitable resistance for the desired power output and voltage.
- Corrosion resistance: Consider a wire with good resistance to oxidation and corrosion for applications in harsh environments.
- Cost: The cost of the wire should be appropriate for the budget of the application.
Based on these factors, some common heat wire options include:
- Nichrome: Nichrome is a nickel-chromium alloy wire with a high resistance to high temperatures and good electrical conductivity.
- KA1: KA1 is a ferritic iron-chromium-aluminium alloy wire with high resistance to oxidation and corrosion.
- Stainless Steel: Stainless steel wire can offer good resistance to high temperatures, corrosion, and oxidation, but may have lower electrical conductivity than nichrome or KA1.
It’s important to note that the best heat wire for a specific application can vary, and it’s recommended to consult a specialist to determine the most suitable option.
Nichrome vs Stainless Steel Wire
Nichrome and stainless steel are both commonly used materials in heating elements and other high temperature applications. However, they have some differences:
- Composition: Nichrome is a nickel-chromium alloy, while stainless steel is an iron-chromium alloy.
- Resistance: Nichrome has a higher electrical resistance compared to stainless steel, making it a better choice for heating elements where high resistance is required.
- Melting Point: Nichrome has a higher melting point compared to stainless steel, making it more suitable for high temperature applications.
- Corrosion Resistance: Stainless steel has better corrosion resistance compared to nichrome, making it a better choice for applications where corrosion is a concern.
- Conductivity: Nichrome has a better electrical conductivity compared to stainless steel, making it more suitable for applications where high conductivity is required.
- Cost: Nichrome is typically more expensive compared to stainless steel, although this can vary depending on the specific type of stainless steel.
Ultimately, the choice between nichrome and stainless steel will depend on the specific requirements of the application, such as operating temperature, resistance, corrosion resistance, and cost. It’s recommended to consult a specialist to determine the most suitable option.
Can I Bend It?
Yes, you can bend 0.42mm Ni80 wire, but it may require some effort and care. Ni80 wire is a type of resistance wire with a high resistance to high temperatures and good electrical conductivity, but it can be brittle and may break if bent too much or too quickly.
To bend 0.42mm Ni80 wire, you can use pliers or other tools that can grip the wire without damaging it. You can also heat the wire to make it more flexible, but be careful not to damage the wire or yourself. After bending the wire, it is recommended to cool it gradually to prevent any thermal stress.
What Is The Resistance Calculation For 0.42mm Nichrome 80?
The resistance of a 0.42mm Nichrome 80 wire can be calculated using the following formula:
Resistance (R) = ρ * L / A
ρ (rho) is the resistivity of Nichrome 80, which is around 1.10 x 10^-6 ohm-metre
L is the length of the wire in metres
A is the cross-sectional area of the wire in square metres
So, for a 0.42mm Nichrome 80 wire with a length of L metres:
A = π * (d/2)^2 = π * (0.42/2 x 10^-3)^2 = 1.12 x 10^-8 m^2
Resistance (R) = 1.10 x 10^-6 ohm-metre * L / 1.12 x 10^-8 m^2 = L / (1.12 x 10^-8 / 1.10 x 10^-6) = L / 0.98 ohm/metre
So the resistance of the 0.42mm Nichrome 80 wire is equal to its length in metres divided by 0.98 ohm/metre.
