E like me ka haku mele, kakeleawe berylliumme ka 0.2% ～ 0.6% ka beryllium o ka conductivity kiʻekiʻe (electrical and thermal);Loaʻa i ka beryllium keleawe ka ikaika kiʻekiʻe o 1.6% ~ 2.0%.

Wahi a ke kaʻina hana, hiki ke hoʻokaʻawale ʻia i ka hoʻoleikeleawe berylliuma me ke keleawe beryllium deformed.ʻO C ka mea hao keleawe beryllium kaulana loa ma ka honua.ʻO ke keleawe beryllium deformed ka C17000, C17200 (ka keleawe beryllium ikaika kiʻekiʻe) a me ka C17500 (ke keleawe beryllium conductivity kiʻekiʻe).ʻO ke keleawe beryllium hoʻoheheʻe e pili ana i ka C82000, C82200 (kiʻekiʻe conductivity cast beryllium copper) a me C82400, C82500, C82600, C82800 (kiʻekiʻe-ikaika aahu-kūpaʻa beryllium keleawe).

ʻO ka mea hana nui loa o ka beryllium copper alloy ma ka honua ʻo Brush Company, nona nā kūlana ʻoihana e like me nā kūlana honua a loaʻa iā ia kekahi mana.ʻO ka moʻolelo o ka hana keleawe beryllium ma Kina ua aneane like me ka Soviet Union mua, ʻo ʻAmelika Hui Pū ʻIa a me nā ʻāina ʻē aʻe, akā aia wale nō ka beryllium bronze QBe1.9, QBe2.0 a me QBe1.7 ikaika kiʻekiʻe i helu ʻia ma ka ʻāina. maʻamau.Ua hoʻokomo ʻia nā keleawe beryllium conductivity kiʻekiʻe a i ʻole ka beryllium keleawe i loko o ka hana nui e like me nā pono o ka hoʻomohala ʻana o ka ʻoihana ʻaila a me ka ʻoihana pale aupuni.
