ʻO kēia huila he ea melted nickel-base alloy, i hoʻomohala ʻia e Rolls Royce (1971) Ltd. e hāʻawi i kahi mea pepa i hiki ke hana maʻalahi a hāʻawi i ka ductility i hoʻomaikaʻi ʻia i nā hui welded e pani i ka alloy NIMONIC 80A. e hoʻokō i nā pae hoʻolālā kikoʻī e pili ana i ke koʻikoʻi hōʻoia a me ka ikaika kolo.Loaʻa iā ia i kēia manawa ma nā ʻano maʻamau a pau. ʻO nā ʻenehana wili no kēia mea hoʻohui e like me nā mea maʻamau no nā makahiki ʻē aʻe - hardenable nickel base alloys.uring salvage kuʻihao hana, a pre weld wela-hana 'aʻole pono ma ka makahiki-paʻakikī ana ana akā, he ma hope makahiki -hardening lapaʻau mea makemake ma hope o nā mea a pau salvage kuʻihao ua pau.
