Hoʻohana: Hoʻohana ʻia ʻo Invar i kahi e koi ʻia ai ke kūpaʻa kiʻekiʻe, e like me nā mea kani pololei, nā uaki, nā anana seismic creep gauge, nā kiʻi pale pale kīwī, nā pahu i loko o nā kaʻa, a me nā wati antimagnetic.Ma ke ana 'āina, i ka wā e hana 'ia ai ka pae ki'eki'e o ke kauoha mua (ki'eki'e-pololei), ua hana 'ia nā ko'oko'o ho'onanea me Invar, ma kahi o ka lā'au, fiberglass, a me nā metala 'ē a'e.Ua hoʻohana ʻia nā struts invar i kekahi mau pistons e kaupalena i ko lākou hoʻonui ʻana i ka wela i loko o kā lākou cylinders.
