Ni80 Nichrome Alloy Wire

The Crazy Wire Company are well known as suppliers of top quality ni80 nichrome alloy 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 0.7mm (21 AWG) ni80 nichrome alloy wire combines the superior properties of nickel (80%) and chromium (20%). This results in a wire that offers impressive resilience against oxidation and corrosion. Many applications are made possible by its resistance characteristics and relatively quick heat-up time. With its 0.7mm diameter, it’s suitable for projects that require a sturdier wire, while also retaining flexibility for design. Ni80 nichrome wire is most often used in home appliances such as toasters and hairdryers. Among the industrial applications are ceramic kilns and laboratory furnaces. Furthermore, it is an apt choice for heating elements in a variety of electronic devices and controlled heating DIY projects. Additionally, it is heat resistant and electrically stable, so professionals in a variety of fields can rely on it.

FAQs About This Wire

Can Nichrome Be Spot Welded?

Yes, nichrome wire can be spot welded. Spot welding is a process in which two pieces of metal are joined together by applying pressure and a high current for a short period of time. This creates a localized heat source that melts the metal, allowing it to flow and fuse together.

Nichrome wire can be spot welded to itself or to other metal materials, such as steel, to create a strong and reliable bond. The welding process requires a specialized spot welding machine and electrodes to apply the pressure and current.

It’s important to note that nichrome wire has a relatively high melting point compared to other metals, which makes it well-suited for use in high-temperature applications. However, care must be taken when welding nichrome wire to avoid overheating, as this can cause damage to the wire and affect its properties.

Additionally, welding of any type can be dangerous, and proper precautions should be taken to ensure the safety of the operator and others in the vicinity.

Could You Use Nichrome Wire For Pickups?

Nichrome wire is not commonly used for pickups in musical instruments, although it is possible to use it in some specialized applications.

Pickups in musical instruments are typically made from magnetic materials, such as iron, steel, or alnico, that respond to the motion of strings to produce an electrical signal. The electrical signal is then amplified and used to drive a speaker or other output device.

Nichrome wire, on the other hand, is a resistor material and generates heat when an electrical current flows through it. It is not magnetic, and therefore does not respond to the motion of strings in the same way that magnetic pickups do.

However, nichrome wire can be used in some specialized applications, such as in custom-built experimental instruments or in certain types of electric instruments that rely on heating elements for sound production.

In general, if you’re looking to build a pickup for a musical instrument, it’s best to use materials and techniques that have been proven to work well for that specific application.

Is Nichrome Wire An Ohmic Conductor?

Yes, nichrome wire is considered to be an ohmic conductor, which means that its resistance is constant and independent of the current flowing through it. In other words, the relationship between the voltage applied across the wire and the current flowing through it is linear, and is described by Ohm’s law (V = IR), where V is the voltage, I is the current, and R is the resistance.

This makes nichrome wire a useful material for heating elements, where a constant and predictable level of heating is desired. It’s also why nichrome wire is often used in applications such as electrical heating, heating tapes, and resistance heating.

Will A Hot Wire Cutter Cut Polystyrene?

Yes, a hot wire cutter can be used to cut polystyrene (also known as Styrofoam). Polystyrene is a type of foam that is commonly used for insulation, packaging, and as a base material for craft projects. Because polystyrene is a thermoplastic material, it can be easily melted and cut with a hot wire.

The process of cutting polystyrene with a hot wire cutter is similar to cutting other types of foam. The wire is heated to a high temperature, and the heat is used to melt the foam as the wire is moved through it. This allows for precise cuts and eliminates the need for sawing or other cutting methods that can be messy or difficult.

However, it’s important to note that cutting polystyrene with a hot wire can produce fumes that can be hazardous to breathe. It’s recommended to work in a well-ventilated area and wear a protective mask to avoid inhaling the fumes.
