基本性能：Ni-Cr合金具优良的综合性能，是制作高PING质电阻电热元件的S选品种。具有抗氧性好，强度高、 无磁性、较好的耐腐蚀性和焊接性、不软化等一系列优点；在长时间使用时，BU变形且用久性伸长很小；电阻值 稳定，变化小。
Brand: Cr20Ni80, Crl5Ni60, Cr30Ni70, Cr20Ni35, Cr20Ni30, 6J10, 6J15, 6J20,6J22, 6J23, 6J24, etc. Executive standard: GB/T 1234-1995, etc.
Basic performance: ni-cr alloy has excellent comprehensive performance and is the first choice for making high quality resistance heating elements. It has a series of advantages such as good oxygen resistance, high strength, non-magnetic, good corrosion resistance, weldability and non-softening. When used for a long time, it does not deform and the permanent elongation is very small. The resistance value is stable and varies little.
