Presyo ng Stock 1mm*10mm 0Cr25Al5 Flat Ribbon Round Burr Bright Surface Strip
1. Panimula
FeCrAl alloys na ginagamit sa malawak na hanay ng mga application na may mataas na temperatura.
Ang Constantan [Cu55Ni45] ay may mababang temperatura na koepisyent ng resistivity at bilang isang tansong haluang metal, ay madaling ihinang. Ang iba pang mga haluang metal na patuloy na lumalaban ay ang manganin [Cu86Mn12Ni2], Cupron [Cu53Ni44Mn3] at Evanohm.
Ang pamilya ng Evanohm ng nickel-chrome alloys [Ni72Cr20Mn4Al3Si1], [Ni73Cr20Cu2Al2Mn1Si], ay may mataas na resistensya, mababang temperatura na koepisyent ng paglaban, mababang electromotive force (Galvani potential) kapag nakikipag-ugnayan sa tanso, mataas na tensile strength, at napaka-stable din patungkol sa sa paggamot sa init.
