本文报导一种新型的限流用电阻便金。它具有很高的正电阻温度系数,为一般康铜、锰铜等电阻合金的72倍。低的电阻率,比康铜、锰铜等电阻合金约低32%。合金的抗氧化性能良好。从室温至约600℃温度范围内,电阻和温度间的关系基本上呈现线性关系。在干燥空气中,合金的最高使用温度可达600℃。本合金不能用热处理方法使之硬化,但可用冷加工方法给予强化。合金的冷、热加工性能优良,焊接性好。本合金可作低温加热器中的发热元件,电器产品中的限流控温元件,如快热电烙铁中的限流电阻元件等。
This article reports a new type of current limiting resistor drop. It has a very high positive temperature coefficient of resistance for the general Kang, manganese and other resistance alloy 72 times. Low resistivity, better than constantan, manganese and other resistance alloy about 32% lower. The oxidation resistance of the alloy is good. From room temperature to about 600 ° C, the relationship between resistance and temperature shows a substantially linear relationship. In dry air, the maximum temperature of the alloy up to 600 ℃. The alloy can not be hardened by heat treatment, but can be strengthened by cold working method. Alloy cold, hot processing performance, good weldability. The alloy can be used as a heating element in a low-temperature heater, a current-limiting temperature control element in an electric appliance, such as a current-limiting resistance element in a rapid thermal soldering iron.
