1. Cov pas nrig yog muab rau hauv cov kab ncaj nraim kom ua tiav lossis zoo li tus neeg siv khoom mus rau qhov kawg.Kev tsim ua tiav ua ntej hnub nyoog hardening.Mechanical processing feem ntau yog tom qab hardening.Cov kev siv ib txwm muaj xws li:
▪ Cov kabmob thiab lub tes tsho ntiv tes uas yuav tsum tau saib xyuas tsawg dua
▪ Cov yam ntxwv ntawm kev tiv thaiv vuam phom
▪ Core rods thiab inserts ntawm txhaj tshuaj pwm thiab hlau tuag castings
▪ Kev sib txuas lus kev lag luam txuas

2. Bars kuj muaj nyob rau hauv cov strips ncaj nraim, tab sis ntxiv rau lub voj voog hla ntu, square, rectangular thiab hexagonal kuj muaj ntau heev.Cov kev siv xws li:
▪ Hnav-tiv taus lub rooj tsavxwm
▪ Qhia cov tsheb ciav hlau thiab cov tsheb npav
▪ Threaded fasteners
▪ Resistance vuam

3. Tubes muaj ib tug series ntawm txoj kab uas hla / phab ntsa thickness ob peb ua ke, xws li redrawn ultra-thin-walled qhov chaw, nyias-walled ncaj-drawn hlab, thiab kub-ua hauj lwm tuab-walled hlab.Cov ntawv thov raug raws li hauv qab no:
▪ High-elasticity, high-strength kav, yoj taw qhia thiab pitot raj rau cov twj paj nruag
▪ Bearings thiab pivot ntsiab ntawm aircraft tsaws iav
▪ Lub tes tsho peb lub taub hau ntev ntev
▪ Cov vaj tse muaj zog-resistant ntawm precision magnetic teb ntsuas thiab lwm yam twj paj nruag

Ib qho tseem ceeb ntawm kev siv cov pas nrig, tuav thiab cov raj yog rau cov khoom siv rau kev ua haujlwm vuam.Beryllium tooj liab ua tau raws li qhov kev xav tau ntawm kev lag luam los ntawm nws qhov hardness thiab conductivity los xyuas kom meej qhov tseeb ntawm cov qauv thiab cov kav ntev ntawm electrodes.Nws yog ib qho yooj yim los tsim nyob rau hauv dabtsi yog khoov thiab machining, thiab kuj txo tus nqi ntawm kuj welding.
