Precision Alloy
Nichrome is a strong and ductile alloy that consists of chromium, nickel and minor additions of other elements. Developed in America in 1905, the alloy is capable of combining two properties - heat resistance and electrical resistance, which are determined by various factors.
With a large increase in the operating temperature, the electrical resistance of nichrome remains at the level. Due to its high plasticity, it can be easily twisted into a spiral, and it does not sag when heated. In total, nichrome wire is used for the manufacture of resistance elements, in rheostats, resistors, and in electric heating equipment. Heating elements made of nichrome are durable, since the alloy is able to withstand mechanical loads, and can work even in aggressive environments. Nichrome wire is made of almost any diameter, this is due to its high yield point. price, but reliability, quality and durability fully compensate for it.
The most popular brands of nichrome alloy are Х20Н80 and Х15Н60. Alloy of nichrome Х20Н80, as can be seen from the marking, consists of 20% chromium, and 80% nickel. Its melting point is 1200 ° C and its resistivity is 650 Ohms /cmf. The nichrome brand keeps its shape perfectly and has high heat resistance and plasticity. It is the plasticity that makes it possible to apply “cold” rolling to the alloy, which is less energy-intensive and cheaper.
Nichrome brand Х15Н60 consists of 60% nickel, 16% chromium, and 24% iron. Its melting point is 1390 ° C, and its resistivity is 675 Ohms /cmf. Due to the high ductility of the alloy, it can be easily sharpened, welded, drawn, and stamped. In cross-section, nichrome mainly contains a circle (since it is the most optimal in the ratio of the cross-sectional area to the perimeter of the nichrome wire), less often a square, a hexagon.
Nichrome wire, depending on the purpose, is marked:
• letter H - wire for heating elements;
• letter C - wire for resistance elements;
• letters TEN - for tubular electric heaters.
Nichrome wire is usually produced with a diameter of 0.1 to 10 mm. The alloy is used in a wide variety of industries. It is used to make heating elements of electric furnaces, cutting elements, as well as in other electric heating devices. In industry, nichrome products are often used in air and water heaters. Also, the alloy is often used for the manufacture of drills, electrical wires, thermocouples, electrodes, and other elements in very aggressive working environments. Nichrome wire has a density of 8.4 g /cm3.
