Nickel Chromium Resistance Wire, Nichrome 80, 20 AWG

This nickel chromium resistance wire is suitable for heater wire and hot wire cutting use. It is nominally composed of 80 percent nickel and 20 percent chromium and meets ASTM B267 standards for resistance wire. The wire has a maximum operating temperature of 1177 degrees C (2150 degrees F), is corrosion resistant, and resists oxidation at high temperatures. This resistance wire is suitable for use in heater wire applications such as toasters and cutting wire applications such as foam rubber cutters. Electrical wire carries an electric current or grounds an electrical device. The amount of current a wire can carry is proportional to its size (gauge), and the wire is generally sheathed with coatings and coverings to insulate and protect it from moisture, chemicals, heat, and abrasion. Copper is the primary material for electrical wire, but alloys are sometimes used to increase its strength or its resistance to chemicals and the environment. Wire can be composed of a single strand or of many smaller strands, depending on its use, and is typically annealed to improve its ductility. Electrical wire is commonly used in industrial, electronic, and automotive applications.

    To whom it may concern,
    Depending on your business, you are a very lucky person for reading these comments. If you are the type of person who likes to bend plastic and fabricate with it, then you are not just lucky, you are extremely fortunate. The reason is that you can stop looking for solutions for making heat strips. This exact type of resistance wire which is really ridiculously inexpensive compared to previous solutions, is all you'll ever need.

    I could go on and on about this wire. Let's start with performance. Using this wire and about $10 in materials, I made a heat strip that far out performs my previous model that uses fiberglass encased heat strip. Keep in mind this cost does not include the price of a variac which you must get if you're going to use this stuff. The wire is thin enough to make it very convenient to store, but thick enough to stand up to the abuse of tension, current and heat. The wire must be used under approximately 5 to 10 pounds of tension. It is certainly strong enough to hold up to this use. I am still fine-tuning my heat strip and going through this wire in the process. Because it is so cheap, it is no problem to just get more. The wire is so versatile that I intend to try to make the bending shapes and patterns. I am very excited about using this wire and will keep you posted on my progress. Bottom line: if you bend plastic then get this wire.
