Solder - for joining contact pieces to thermocouple legs

摘要

Addn. to 1, 804, 108 which concerns a solder contg. Bi and which has the compn. BixMe1-x with 0.6 = x =0.99, and Me one of the metals Ge, Se, Te, Co, Ni, Rh, Pd or Pt. Other metals suitable are Cu, Ag, Au and Zn. The m.pts. vary from 300-415 degrees C and the solder has good wetting properties on thermocouple legs made of e.g. Bi2Te3 or AgBiTe2, and contact materials such as Cu, Pd, co, Au, Fe. partic. Ni and Ag.
