WHY IS REXALLOY ®™ BEST FOR HOMOGENIZER PARTS?

Conventional indentation hardness tests or Rockwell tests do not generally determine the relative wear resistance of REXALLOY ®™ as compared with other materials.

REXALLOY ®™, for non-cutting applications, has a hardness of about 49-54 HRC, however the hardness of the individual micro-constituents gives an entirely different picture. Although the matrix in REXALLOY ®™ is softer, the primary carbides in REXALLOY ®™ are much harder than the large carbides of other materials, yet in concert with it’s cobalt & chrome matrix, combined with casting and processing techniques created for homogenizer parts, REXALLOY ®™ is far more “tough” than comparable materials. High pressure pump manufacturers played a role in the development of REXALLOY ®™ and it’s processing for pump parts to best suit all the requirements of high service demand valves and valve seats. Time and the intense marketing of other manufacturers has pulled some of the original REXALLOY ®™ users over to what is initially believed to be less expensive “so called” similar materials, but they will never be REXALLOY ®™.

Conventional Rockwell tests provide an average hardness which masks the effect of hard and soft constituents in a cast heterogeneous alloy of this type. It is the large surface area of the massive primary carbides which produces the “tough” wear resistant quality of REXALLOY ®™. Plain and simple, THERE IS NO SUBSTITUTE.
