ʻO ka keleawe Beryllium kahi hui keleawe i hoʻopaʻa ʻia me ka beryllium (Be0.2~2.75%wt%), i hoʻohana nui ʻia i nā huila beryllium āpau.
Ua ʻoi aku kona ʻai ʻana ma mua o 70% o ka nui o ka hoʻohana ʻana i ka beryllium i ka honua i kēia lā.ʻO ka Beryllium copper kahi mea hoʻopaʻa paʻakikī paʻakikī, nona ka ikaika kiʻekiʻe, ka paʻakikī, ka palena elastic a me ka palena luhi ma hope o ka hoʻoponopono ʻana i ka wā kahiko, a he liʻiliʻi elastic hysteresis.
A loaʻa i ka corrosion kū'ē (corrosion rate o beryllium bronze alloy i loko o ke kai: (1.1-1.4) × 10-2mm / makahiki. Corrosion hohonu: (10.9-13.8) × 10-3mm / makahiki.) Ma hope o ka corrosion, ka ikaika o ka beryllium keleawe alloy , ʻAʻohe loli o ka Elongation rate, no laila hiki ke mālama ʻia ma mua o 40 mau makahiki i ka hoʻihoʻi wai,
ʻO Beryllium copper alloy kahi mea hiki ʻole ke hoʻololi ʻia no ke ʻano o ka submarine cable repeater structure.
Ma ka waena: ʻo ka hohonu o ka corrosion makahiki o ka beryllium copper ma kahi ʻano o ka liʻiliʻi ma mua o 80% (ma ka lumi mahana) ʻo 0.0012 a 0.1175mm, a ua wikiwiki iki ka corrosion inā ʻoi aku ka nui ma mua o 80%.ʻAʻahu i ke kūpaʻa, ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, non-magnetic, kiʻekiʻe conductivity, ka hopena a me ka ʻole o nā huna ahi.I ka manawa like, loaʻa iā ia ka wai maikaʻi a me ka hiki ke hana hou i nā hiʻohiʻona maikaʻi.Ma muli o ka nui o nā waiwai o ka beryllium copper alloy, ua hoʻohana nui ʻia i ka hana ʻana.
