Fecral 'waxaa lagu sameeyaa heerkul sare, friritic bir-chrominium-aluminium-ka kaas oo loo isticmaali karo heerkulka ilaa 1350degs. Codsiyada caadiga ah ee fcral waa sida walxaha kuleylka korantada ee foornooyinka heerkulka leh ee dawada kuleylka, dhoobada, galaaska, birta, iyo warshadaha elektiroonigga ah.

Oo leh nolosha dheer ee nolosha. Si toos ah u isticmaali kara. Markii lagu isticmaalayo korantada qiimeeyay, majiro arrin kacsan. Iyo badal u ah Wire ee qaaliga ah.

Feejigyada Fcral waxaa lagu gartaa iska caabin aad u fiican oo ka hortag ah iyo xasillooni aad u wanaagsan oo ka dhalata nolosha dheer.

Caadi ahaan waxaa loo isticmaalaa walxaha kululaynta korantada ee foornooyinka warshadaha iyo qalabka guryaha.

Fre-cr-al al al alle oo leh wax iska caabin leh iyo heerkulka ugu habboon ee heerkulka ka badan tan nicr aloy oo sidoo kale leh qiime hooseeya

Irod-chrome-aluminium xargaha korantada korantada ee korantada ayaa si weyn loogu isticmaalaa samaynta walxaha kuleylka korantada ee qalabka guryaha iyo foornooyinka warshadaha. Codsiyada caadiga ah waa bir-soo-baxa fidsan, mashiinnada birta, kuleyliyeyaasha biyaha, gogosha balaastigga ah waxay dhintaan, birta iibinta, walxaha tuubbada tuubbada leh

Alaabooyinkayaga ayaa si balaadhan loogu isticmaalaa qalabka daaweynta kuleylka, qaybaha otomaatiga, birta iyo wax soosaarka birta,

Warshadaha aluminium, qalabka macdanta, qalabka patrochemical, mashiinka galaaska, mashiinka dhoobada, mashiinka dhoobada,

mashiinada cuntada, mashiinka dawooyinka, iyo warshadaha injineerinka korantada.
