Cov yam ntxwv thiab cov ntawv thov

BT22 titanium alloy tuav muaj cov yam ntxwv xws li lub zog siab, muaj kev nyuaj siab, thiab ua tau zoo. Nws yog ib qho ze - Hom Titanium Alloy nrog kev ua tau zoo heev. Cov yam ntxwv zoo tshaj plaws ntawm BT22 titanium alloy, suav nrog qhov siab {5} Lub zog ua hauj lwm, thiab muaj zog, muaj kev nyiam dav hauv kev lag luam xws li aerospace.

Nrog rau kev txhim kho sai ntawm Tuam Tshoj tus neeg siv khoom lag luam Aerospace, cov kev ua tau zoo yuav tsum tau ua ib qho kev ua haujlwm ntawm kev ua haujlwm hauv kev ua kom nce ntxiv. Tshwj xeeb, txhim kho qhov ua tau zoo ntawm titanium alloy cov ntaub ntawv nyob rau hauv high- sov rau qhov kev txhim kho ntawm lub tshuab thev naus laus zis. BT22 titanium alloy tuav feem ntau siv nyob rau hauv cov dav hlau loj, thiab lawv tau siv dav hauv lub dav hlau xws li Lavxias teb li cas.
