## Overview

Nichrome 80 20 gauge wire, 50 ft long, engineered for high-temperature industrial and hobby use. Featuring a robust nickel-chromium alloy with 0.64 Ohms/ft resistance and annealed softness, it delivers fast, uniform heating up to 2150°F while maintaining mechanical stability. Ideal for hot-wire foam cutters, heaters, ceramics, and electronic repairs, this USA-made wire combines durability with precision for professional-grade results.

## Description

**Wire Specifications:** - Diameter: 20 Gauge / 0.81mm - Shape: Round - Alloy: Nichrome 80 (80% Ni, 19.5% Cr, 1.45% Si) - Length: 50 ft. - Heat Treatment: Annealed (soft) - Melting Temperature: 2552°F / 1400°C - Maximum Continuous Operating Temperature: 2150°F / 1180°C - Resistance: 0.635 Ohms/ft at room temperature Nichrome 80 Wire has a low temperature coefficient of resistance and minimal change in resistance during its service life. These properties ensure faster heat-up times, more uniform operating temperatures, and a longer useful life. Its excellent mechanical stability minimizes variables in element design, ensures even stretch in coiled form, and eliminates problems such as shrinkage, growth, sag, or distortion in use. This wire is intended for the repair and maintenance of electronic components. Typical applications include industrial and hobby hot-wire foam cutters, internal support in ceramics, home and industrial heaters, diffusion heaters, dishwashers, cooking plates, electric blankets, hair dryers, kerosene-fired appliances, kettles, refrigerators, rice cookers, tumble dryers, washing machines, and electrical heating elements in high-temperature furnaces used in heat treatment, glass, steel, and electronics industries.

Review: Great Value Nichrome Wire for Ceramics and Kiln Use - This Nichrome 80 20 gauge wire is a great value and works very well for ceramics. I use it in my studio for projects that are fired at low fire cone 05, and it has held up without any issues. The wire is easy to work with and strong enough for a variety of ceramic applications. It performs reliably in the kiln and maintains its integrity through firing. The kids at my studio love using it for their projects, and it has been durable enough to handle frequent use. If you are looking for nichrome wire for ceramic work, kiln projects, or classroom use, this is a solid and affordable option.
Review: Good wire for cone 10 - Fires at cone 10. Does not melt. I have not tested this holding heavier objects.

## Questions & Answers

**Q: Is this wire strong enough to make a "skeleton" for a clay sculpture of a standing person? I need wire that is about the thickness of a paper clip.**
A: No, it's not. I've done some sculpting myself, but never a human form. I found the following at https://www.instructables.com/id/CREATING-A-FIGURE-ARMATURE-FOR-SCULPTURE/
(Materials needed) -1/8th aluminium armature wire
-1/16th aluminium armature wire
-Small gauge galvanized steel wire (18 gauge or thinner is best)

**Q: Is this wire insulated?**
A: No it’s not insulated.this wire gets red hot when hooked up to a power source so why would you want to insulate it.this type of wire is used in things such as hair dryers etc.

**Q: What voltage is best for this wire to reach 600*C?**
A: I have no way of measuring the temperature of the wire.  I use a BMOUO 12V 30A DC Universal Regulated Switching Power Supply 360W ordered from Amazon.  I used a dimmer switch to control output to Nichrome wire.  This setup was enough to make the wire glow red hot and even burn in two if adjusted too high.

**Q: Can i use this wire for a pendant lamp, like a electrical wire?**
A: No.please don’t
