4J36 (Invar) hoʻohana ʻia i kahi e koi ʻia ai ke kūpaʻa kiʻekiʻe, e like me nā mea kani pololei, nā uaki, nā anana creep seismic, 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 ho'okō 'ia ai ka pae ki'eki'e o ka pae ki'eki'e, ua hana 'ia nā limahana Papa (leveling rod) 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.

4J36 hoʻohana i ka oxyacetylene welding, uila arc welding, welding a me nā ʻano hana wili. No ka mea e pono ke pale ʻia ka coefficient o ka hoʻonui a me ka hoʻohui kemika o ka huila ma muli o ke kumu o ka kuʻi ʻana i ka hoʻololi ʻana i ka haku mele, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka Argon arc welding welding filler metala ʻoi aku ka maikaʻi o 0.5% a 1.5% titanium, i mea e e ho'ēmi i ka porosity weld a me ka māwae.
