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.
