Uns K93600 Invar 36 Ribbon Precision Expansion Alloy Flat Wire
Uns K93600 Invar36 Ribhoni Precision Kuwedzera Alloy Flat Wire
(Zita rakajairika: Invar, FeNi36, Invar Standard, Vacodil36)
4J36 (Invar), inozivikanwawo seFeNi36 (64FeNi kuUS), iine nickel-iron alloy inozivikanwa neyakasiyana yakaderera coefficient yekuwedzera kwekupisa (CTE kana α).
4J36 (Invar) inoshandiswa panodiwa kugadzikana kwepamusoro-soro, senge zviridzwa, wachi, seismic creep gauge, terevhizheni mumvuri-mask mafuremu, mavharuvhu mumamotor, uye antimagnetic wachi. Mukuongorora ivhu, kana yekutanga-yakarongeka (yakakwirira-chaiyo) kukwirisa kukwirisa kunofanirwa kuitwa, vashandi veNhamba (leveling rod) inoshandiswa inogadzirwa neInvar, panzvimbo yehuni, 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.
