Alchrome 875 FeCrAl silig alloy ah
Alchrome 875 alaabada xargaha qaboojiya ee cabbirka weyn waxaa loo isticmaali karaa foornada iska caabbinta heerkulka sare. Tababarku wuxuu leeyahay
waxay caddeeyeen in: habka wax soo saarka uu yahay mid deggan, waxqabadka isku dhafan ayaa wanaagsan. Waxay leedahay oksaydhyo heerkul sare oo wanaagsan
iska caabin iyo nolol adeeg oo dheer; guryaha dabaylaha aad u fiican at habaynta heerkulka qolka, fudayd ee
farsamaynta qaabaynta; dib u soo kabashada yar iyo wixii la mid ah. Waxqabadka habaynta waa mid aad u wanaagsan; hawlgelinta
heerkulku wuxuu gaari karaa 1400 .
Tilmaamaha ugu muhiimsan iyo isticmaalka:
Tilmaamaha Alaabta caadiga ah: 0.5 ~ 10 mm
Isticmaalka: inta badan waxaa loo isticmaalaa foornada biraha budada ah, foornada faafinta, kuleyliyaha tuubada shucaaca iyo dhammaan noocyada kala duwan ee sare-
foornada heerkulka jidhka kululaynta.
