0.5mm Heating Resistance Nichrome Wire

Description

The electric heating wire must have an appropriate resistivity in order to achieve the purpose of heating when powered on. If the resistivity is too high or too low, very short or very long, very thin or very thick heating wires are required. This causes difficulties in manufacturing. The melting point should be relatively high, so that it won't melt when it stops heating; at high temperatures, the chemical stability should be relatively high, so that it doesn't oxidize quickly and has a long lifespan.

When the voltage is constant, as the temperature rises, the 0.5mm Heating Resistance Nichrome Wire will increase and the power will decrease slightly. When the heat generation and heat dissipation reach equilibrium, the temperature will stabilize. The power of the Nichrome wire is determined by the material, the thickness and length. If it is the same material, the longer and thinner the heating wire is, the greater the resistance will be and the smaller the power will be. 

0.5mm heating resistance nichrome wire is electrical components which change the electric energy into the internal energy. Generally speaking, the resistance of metals increases with the temperature rises.Nickel chromium wire has the feature of weldability, high electrical conductivity, suitable linear expansion coefficient,has good strength at high temperature, low resistivity. With high melting point, corrosion resistance, good mechanical properties.

The power set of 0.5mm heating resistance nichrome wire is that the greater the power, the smaller the total resistance.The nickel chromium heating wire resistivity has a proper range, if the resistivity is too large or too small, it needs very short or very long, very thin or very thick nickel chromium wire, so it is difficult to manufacture and use the electric heater of different powers.

An important parameter of nickel chromium heating wire is the surface power. The resistivity is too large, through a certain current, the surface power is also large. So the electric appliance of small power, choose small diameter small current, but the size of current decides at the size of resistance, the length of resistive heating wire and diameter are calculated.

However, it should be noted that the manufacturing of nickel-chromium alloy heating wires requires the use of nickel. The price of this metal is higher than that of iron, chromium and aluminium. Therefore, the manufacturing cost of nickel-chromium alloy heating wire is relatively high, which is not conducive to cost control.
