ʻO ka Beryllium nickel copper kahi hui keleawe kumu me ka hopena paʻa supersaturated.ʻO ia ka mea hoʻoheheʻe nonferrous me ka hui maikaʻi o nā waiwai mechanical, nā waiwai kino, nā waiwai kemika a me ka pale ʻana i ka corrosion.Ma hope o ka hoʻonā a me ka mālama ʻana i ka wā kahiko, loaʻa iā ia ka palena ikaika kiʻekiʻe, ka palena elastic, ka palena a me ka luhi luhi e like me ke kila kūikawā;I ka manawa like, loaʻa iā ia ka conductivity kiʻekiʻe, ka conductivity thermal, ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana, ke kūpaʻa creep kiʻekiʻe a me ke kūpaʻa corrosion.Hoʻohana nui ʻia ia i ka hana ʻana i nā mea hoʻohui like ʻole, e hoʻololi ana i nā mea electrode welding no nā mold me ke kiʻekiʻe kiʻekiʻe a me nā ʻano paʻakikī i hana ʻia me ke kila, nā mīkini make-casting, injection molding machine punches, wear and corrosion resistant work, etc.
