4J36 (Invar) inoshandiswa panodiwa kugadzikana kwepamusoro-soro, zvakaita sezvishandiso zvekushandisa nemazvo, wachi, magauge ekudengenyeka kwepasi, mafuremu emumvuri weterevhizheni, mavharuvhu ari mumota, uye mawachi ekudzivirira magineti. Pakuongorora nyika, kana kuyera kwepamusoro-soro (kwakanyatsojeka) kuchiitwa, tsvimbo yeLevel (leveling rod) inoshandiswa inogadzirwa neInvar, pachinzvimbo chehuni, fiberglass, kana zvimwe simbi. Ma "Invar struts" aishandiswa mune mamwe mapiston kuderedza kupisa kwawo mukati memasirinda avo.

4J36 inoshandisa oxyacetylene welding, electric arc welding, welding nedzimwe nzira dzekuwelding. Sezvo coefficient yekuwedzera uye makemikari e alloy akabatana anofanirwa kudzivirirwa nekuti welding inokonzera shanduko mu alloy composition, zviri nani kushandisa Argon arc welding welding welding filler metals zviri nani ive ne 0.5% kusvika 1.5% titanium, kuitira kuderedza weld porosity uye crack.
