Beryllium copper alloys (BeCu) have been recognized for their potential to provide high strength with good conductivity.  C17200 beryllium copper falls into this category with high strength and moderate conductivity, but this alloy also has other attractive properties. C17200 exhibits very low magnetic susceptibility, resists galling, and can be age hardened to yield strengths of 100-120 ksi with elongation values of 10-20% along with having high thermal conductivity.  Even more C172 can be tailored to achieve even greater yield strengths between 140-160 ksi.  These attractive properties make this alloy a very popular choice in the manufacture of drill collars, instrument housings and other applications in oil and gas well drilling.
