Vim tias cov yam ntxwv ntawm lub teeb pwm thiab lub zog siab, txhuas ib txwm siv hauv kev ua haujlwm los txhim kho nws txoj kev ua haujlwm zoo, kev nyab xeeb, thiab lub neej.

Piv txwv li, hauv cov subways ntau, aluminium alloy yog siv rau lub cev, qhov rooj, chassis cov khoom siv, xws li radiators thiab hlau ducts.

6061 feem ntau yog siv rau cov qauv txheem xws li carriage qauv thiab chassis.

5083 yog tsuas yog siv rau cov plhaub, lub cev, thiab cov ntoo hauv pem teb, raws li nws muaj cov zoo corrosion tsis kam thiab weldability.

3003 tuaj yeem siv tau raws li cov khoom siv xws li skylights, qhov rooj, qhov rai, thiab panels sab hauv.

6063 Muaj cov cua sov tsis zoo, yog li nws tuaj yeem siv rau hluav taws xob hluav taws xob ducts, cua sov, thiab lwm yam kev siv hluav taws xob.

Ntxiv rau cov qib kawm no, lwm yam txhuas alloys tseem siv hauv kev tsim khoom hauv subwwing, qee qhov tseem yuav siv "txhuas lithium alloy". Cov qib tshwj xeeb ntawm aluminium alloy yuav tsum tau siv tseem yog nyob ntawm cov kev tsim tsim tshwj xeeb tsim.
