The material for the manufacture of refractory filaments with high electrical resistance is nichrome. The opening of this unique alloy we owe the American A. Marsh of the Company Driver-Harris Company. In 1905 he received a patent for his invention, combining in a nickel chromium alloy with a ratio of 4: 1. Nichrome alloys have high electrical resistance, heat resistance, high resistance to corrosion even in aggressive environments. The service life of these products depends on the conditions under which they operate, as well as the composition of the components in the alloy.
• 55−79% Ni vest material ductility, high electrical resistance, unchanged at high temperatures;
• 15−22% Cr impart toughness, enhance corrosion resistance and wear resistance of the material.
The composition can be alloyed by the following elements:
· Silicon (1.5%)
· TEN — used for tubular electric
· H — for heating appliances
· C — for the resistance elements
Range (in mm)
Nichrome has a good combination of heat resistance and high electrical resistance. The minimum coefficient of thermal expansion enables the wire does not sag at significant temperatures. Surface oxides of chromium and nickel alloy impart excellent corrosion resistance, it can be used in harsh environments. Plasticity allows you to roll the thinnest wire and tape in a cold state. Heat resistance helps to maintain the Nichrome wire mechanical loads without deforming or breaking.
Nickel does not apply to low-cost items, and thus the high price Nichrome filament is justified. Keep in mind that cheap analogue of this material has yet been found. To date, the production of nichrome is constantly growing. Prices depend on the fluctuations in world prices for nickel and chrome.
Excellent thermal stability and resistivity allow the use of Nichrome wire for driving the thermal radiation. This thread has been applied in the pharmaceutical laboratory as a thermocouple heater. It is woven into the body of fiberglass heating mantle. At home, you can even assemble homemade induction furnace (for example, aluminum smelting). Calculation of nichrome filament for homemade oven was made as early as the middle of the twentieth century metallurgist Khomutov. In conventional refractory tube (30 cm) wound filament windings is not confined to one another on their tube is wound in a pair of two-millimeter-diameter cord, then coated with a silicate adhesive. Before complete drying, the cord is removed, and is ideal Nichrome spiral coils that are not closed. Finished pipe is wrapped in asbestos.
Nichrome filament in valyankah? I’m not kidding. Modern craftsmen make the insoles with heating for winter fishing. They feed on battery attached to his belt. Not very convenient, but because of the dry and warm feet can suffer. By the way, the British have long been producing self-heating insoles and socks on an industrial scale.
Nichrome thread can be cut foam, Teflon or polyurethane, leaving a smooth flat cut and burr-free cavities. In this form of the cut products may differ a high degree of complexity. The thread of Nichrome is a major component of operating machines that perform cutting curly foam. Jigsaws with a thread of nichrome alloy are used to create decorative items in wood, panels.
