Alecular™ King Racing’s Bi-Metal structure

  • The .015” thick top layer can be squeezed and worn up to .010” (vs. tri-metal .0005”)
    without damaging the crank journals
  • Its Vickers hardness of 40 withstands short duration high loads better
    than softer Babbitt’s Vickers hardness of 15-20
  • The thick top layer provides better macro-particle (>.00025”) embedability vs. a typical tri-metal  Babbitt (.015” thickness vs .0005”)
  • The Alecular  temperature threshold is almost 30% greater
    than tri-metal (450ºF vs.350ºF)

KING developed the HP Series featuring the Alecular™ metal structure. Alecular™’s main benefit is its ability to contend with high loads for short durations. The Alecular™ metal structure was developed for specific race applications such as drag racing  which can benefit from a harder than Babbitt top layer material. Alecular ™also serves other performance applications that use nodular cast iron crankshafts, such as street/strip and some levels of circle track racing.
