ABSTRACT:
A spark plug is equipped with a center electrode composed of two different metals, one of which is embedded in wire or fibre form in the other and wherein at least one of the metals possesses the properties of high electrical and thermal conductivity. The electrode is made by the joint plastic shaping of the two metals to produce a solid metallic bond therebetween. The electrode possesses the advantageous properties of good electrical and thermal conductivity, high corrosion resistance at high temperatures, slow burning rate and high mechanical strength.
