ʻO wai ka ikaika, ka rivet makapo keleawe a i ʻole ka rivet makapo keleawe?
ʻO ke keleawe maʻemaʻe, i ʻike ʻia hoʻi he keleawe ʻulaʻula, he (7.83g / cm3) ka nui o ka paʻa a he 1083 degere ka wahi heheʻe. ʻAʻole ia he magnetic. Loaʻa iā ia ka conductivity maikaʻi, ka conductivity thermal, ke kūpaʻa i ka corrosion a me ka paʻakikī.
Hoʻohana ʻia ka nui o ke keleawe (8.93g / cm3) no ka uhi ʻana me kahi ʻōpuʻu bearing mechanical, kahi mea e pale ai i ke komo ʻana.
ʻOi aku ke kiʻekiʻe o ka nui o ke "keleawe" ma mua o ke keleawe ʻulaʻula, a he paʻakikī ke "keleawe" me ka paʻakikī maikaʻi.
