Abstract
An electric contact material, using a substrate with relatively high mechanical hardness from the gp. of 'refractory' contact materials (e.g. W, Mo, Pt, Ir, Pd, Rh, Re), contains at least in the contact-giving area, a percentage of a contact metal, in atomic combination with it, which increases the ductility of the substrate material by an effect on the crystal lattice and/or counteracts embrittlement by penetration of materials causing lattice defects. Pref. the substrate consists of Mo and the additive is max. 40 (atom)% Re, 0.026% Al, 0.15% Ce, 0.5% V or Zr or Hf or a combination of these. The material avoids redn. in the lifetime due to particles breaking off and detriment to the contact resistance due to inadequate plastic deformability of the material, whilst retaining the advantages of a refractory and mechanically strong matl.
