4J36 (Invar) inoshandiswa panodiwa kugadzikana kwepamusoro-soro, senge zviridzwa, wachi, seismic creep gauges, terevhizheni shadow-mask mafuremu, mavharuvhu mumamotor, uye antimagnetic wachi. Mukuongorora ivhu, kana yekutanga-odha (yakakwirira-chaiyo) kukwirisa kukwirisa kunofanirwa kuitwa, vashandi veLevel (leveling rod) inoshandiswa inogadzirwaInvar, panzvimbo pehuni, fiberglass, kana mamwe simbi. Invar struts yakashandiswa mune mamwe mapistoni kudzikamisa kuwedzera kwemafuta mukati memasilinda avo.

4J36 shandisa oxyacetylene welding, magetsi arc welding, welding uye dzimwe nzira dzekugadzira. Sezvo coefficient yekuwedzera uye kuumbwa kwemakemikari ealloy kwakabatana kunofanirwa kudzivirirwa nekuda kwewelding kukonzeresa shanduko mune alloy kuumbwa, zviri nani kushandisa Argon arc welding welding filler simbi zvine 0.5% kusvika 1.5% titanium, kuitira kuderedza weld porosity uye kuputika.

Nzira yekurapa kupisa
Annealing yekuzorodza stress	Kupisa kusvika 530 ~ 550ºC uye kubata 1 ~ 2 h. Kutonhora pasi
annealing	Kuti ubvise kuomarara, izvo zvinoburitsa muinotonhora-yakakungurutswa, inotonhora yekudhirowa. Anealing inoda kudziyisa kusvika 830 ~ 880ºC muvacuum, bata 30 min.
The stabilization process	Mune inodzivirira midhiya uye inopisa kusvika 830 ºC, bata 20min. ~ 1h, kudzima Nekuda kwekushushikana kunoitwa nekudzima, kudziyisa kusvika 315ºC, bata 1 ~ 4h.
Zvekungwaririra	Haikwanise kuomeswa nekurapwa kwekupisa Kurapa kwepamusoro kunogona kuita jecha, kupukuta kana kunhonga. Alloy inogona kushandiswa 25% hydrochloric acid pickling solution pa70 ºC kubvisa nzvimbo ine oxidized.
