20 Gauge Nichrome Wire

The Crazy Wire Company are well known as suppliers of top quality 20 gauge nichrome 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 20 gauge nichrome wire, with a thickness of 0.8mm, is a versatile and durable wire that is gaining popularity in a variety of applications. Nickel and chromium combine to make this wire. This is ideal for use in high-temperature environments because of its resistance to corrosion and oxidation. The consistent composition of this element ensures even heating, which makes it an excellent choice for electrical appliances and industrial equipment. The superior electrical conductivity of the 20 gauge nichrome wire makes it a reliable conductor for electronics.

It is also great for using in crafting, jewelry making, and other creative projects where precision and durability are paramount due to its strength and flexibility. The wire’s predictable resistance values can be useful for those working on experimental projects or prototyping. Artists and manufacturers alike like this wire because it can withstand extreme temperatures in the realm of ceramics and glasswork. A high melting point ensures durability and performance under constant stress.

A 0.8mm Nichrome wire would have a diameter of 0.8 millimetres, which is thicker than the 0.1mm Nichrome wire. This would make it less delicate and more suitable for applications that require higher current-carrying capacity. However, as with all Nichrome wire, the resistance and temperature coefficient of the 0.8mm wire would depend on its specific composition, wire length, and the operating conditions.

FAQs About This Wire

Does Nichrome Wire Conduct Electricity?

Yes, Nichrome wire conducts electricity. Nichrome wire is made of nickel, chromium, and iron and has a high electrical resistance, which makes it useful for heating elements and resistance heating applications. When an electrical current is passing through Nichrome wire, it generates heat due to the resistance of the wire to the flow of electrical current.

How Nichrome Wire Is Made

Nichrome wire is made through a process known as wire drawing. This process involves taking a starting material, typically a rod or bar, and pulling it through a series of progressively smaller dies to produce a wire of the desired diameter.

The starting material for Nichrome wire is typically an alloy of nickel, chromium, and iron, which is melted and cast into a rod or bar. This material is then drawn through a series of dies to produce wire of the desired diameter and shape.

During the wire drawing process, the wire is subjected to high levels of tension, which can cause it to stretch and thin out. To prevent breakage, the wire is typically lubricated and cooled between each pass through the dies.

After the wire drawing process is complete, the Nichrome wire may undergo additional processing, such as annealing or coating, to improve its properties or suit it for specific applications.

Is Nichrome Wire An Ohmic Resistor?

Yes, Nichrome wire can be considered an ohmic resistor. An ohmic resistor is a type of resistor in which the resistance of the material is constant and does not change with the amount of current passing through it.

Nichrome wire has a high electrical resistance, which makes it useful for heating elements and resistance heating applications. When an electrical current is passed through Nichrome wire, it generates heat due to the resistance of the wire to the flow of electrical current. The resistance of Nichrome wire is largely dependent on its composition, wire length, and operating conditions, but it is generally considered to be constant and ohmic.

Can Nichrome Wire Be Soldered?

Yes, Nichrome wire is good for soldering. Nichrome wire is a nickel-chromium alloy and can be soldered using a high-temperature solder specifically designed for use with nickel-based alloys.

The soldering process involves heating the Nichrome wire and the solder to a high temperature, typically above 600°C, and applying the melted solder to the joint. As the solder cools, it forms a strong bond between the Nichrome wire and the other component being joined.
