新型应变电阻合金4YC8精密箔材的元件特性

Element Characteristic of New Style Strain Resistance Alloy 4YC8 Precise Foil

４ＹＣ８合金，即Ｃｕ－Ｎｉ－Ｍｎ－Ｃｏ应变电阻合金，是重庆仪表材料研究所为解决我国箔式应变计引进生产线用箔材国产化问题，而自行设计创制的一种具有温度自补偿功能、适宜用作高精度箔式应变计的新型铜镍锰合金。该合金精密箔材具有优异的温度自补偿性能和其他性能，特别是其平均热输出系数Ｃｔ和对试件材料的适用性明显优于国外。

Alloy 4YC8 is a kind of Copper Nickel Manganese Cobalt strain resistance alloy.It is suitable for high precise foil strain gages.The precise foil of the alloy is provided with excellent temperature self compensating property and other properties,especially mean thermal output coefficient and adaptability to sample materials.
