Aloyi C-4 Chemical kompositi:

Aloyi C-4 aloyi ndi nickel-chromium-molybdenum aloyi ndi zabwino kwambiri.
kukhazikika kwapamwamba kwa kutentha monga kuwonetseredwa ndi ductility mkulu ndi kukana dzimbiri ngakhale
atakalamba mu 1200 mpaka 1900 F (649 mpaka 1038 C). Aloyi iyi imatsutsa mapangidwe
wa malire a tirigu amalowa m'malo okhudzidwa ndi kutentha kwa weld, motero amawapangitsa kukhala oyenera
kwa ambiri mankhwala ndondomeko ntchito mu chikhalidwe monga welded. C-4 aloyi komanso
ali ndi kukana kwambiri kupsinjika-kudzimbiri kusweka ndi oxidizing atmospheres mpaka
1900 F (1038 C).

Aloyi C-4 aloyi ali ndi kukana kwapadera zosiyanasiyana njira mankhwala
chilengedwe. Izi zikuphatikizapo otentha zakhudzana mchere zidulo, solvents, chlorine
ndi chlorine zakhudzana media (organic ndi inorganic), youma klorini, formic ndi
acetic acid, acetic anhydride, ndi madzi a m'nyanja ndi brine solutions.
Alloy C-4 alloy amatha kupangidwa, kukwiya, komanso kutulutsa mphamvu. Ngakhale a
aloyi imakonda kugwira ntchito molimba, imatha kukokedwa mozama, kupota, kusindikiza kapena kupanga.
kukhomeredwa. Onse wa njira kuwotcherera angagwiritsidwe ntchito kuwotcherera Aloyi C-4
aloyi, ngakhale oxy-acetylene ndi mizere arc njira si ovomerezeka
pamene chinthu chopangidwa ndi cholinga choti chigwiritsidwe ntchito pa dzimbiri. Kusamala mwapadera
ziyenera kutengedwa kuti mupewe kutentha kwambiri.
