C902 Constant Elastic Alloy Hlau 3J53 Hlau Rau Elastic Elements Zoo Elasticity

Hlau Dia 0.1mm-Dia 5.0mm

Cov khoom siv

Lawv feem ntau yog siv los ua cov twj paj nruag, lub cev tsis muaj zog elastic, lub hauv siab, diaphragms.

Kev piav qhia

Lub nag lossis daus hardenable Nickel-Iron-Chromium alloy muaj qhov zoo tshaj plaws tswj tau thermoelastic coefficient
cov yam ntxwv thiab zoo heev oxidation kuj nyob rau hauv high kub cua. Cov hlau tuaj yeem ua tiav
kom muaj qhov hloov pauv tsis tu ncua ntawm elasticity ntawm qhov kub ntawm -45 txog +65oC (-50 txog +150oF).
