Aluminiyɔmu sama rivet nuts (a bɛ fɔ fana ko rivet nuts) ye fɛn ye min bɛ se ka kɛ kosɛbɛ, min bɛ aluminiyɔmu fɛn suguyaw ni sama rivet kɛcogo nafaw fara ɲɔgɔn kan. Ninnu ye a ka fɛnba duuru ye, minnu bɛna ɲɛfɔ yɔrɔ o yɔrɔ:
1. A ka nɔgɔn ani a fanga ka ɲi
A ka nɔgɔn kosɛbɛ : Aliminiyɔmu ka dɔgɔn, o b’a to aliminiyɔmu rivet nuts bɛ kɛ sugandili ɲuman ye girinya-baarakɛminɛnw na minnu bɛ se ka sɛgɛsɛgɛ i n’a fɔ aerospace, mobili nɔgɔya, minɛn minnu bɛ se ka ta, ani jɔli yɔrɔ nɔgɔmanw, o bɛ dɔ bɔ kosɛbɛ girinya bɛɛ lajɛlen na.
Masina fanga bɛrɛbɛrɛ : Hali n’a fanga man ɲi i n’a fɔ nɛgɛ suguyaw ta, ni a bɛ kɛ ni fɛnɲɛnamafagalan hakɛ bɛnnenw ye (i n’a fɔ ka baara kɛ ni 5056, 6061 ani aliminiyɔmu sɔgɔlen wɛrɛw ye) ani ka funteni furakɛ, aliminiyɔmu samali rivet nuts bɛ se ka fanga ni sɛgɛn kɛcogo di min bɛ bɛn doni nɔgɔman ni doni cɛmancɛ baarakɛcogo fanba ma.
2. A bɛ se ka sɔgɔsɔgɔ ka ɲɛ
Filimu min bɛ kɛ ka fɛnw kɛ cogo la min bɛ wele ko natural passivation film : Aluminiyɔmu ɔkisidi ka filimu min bɛ a tanga, o bɛ kɛ aliminiyɔmu sanfɛ, o b’a to a bɛ se ka a yɛrɛ tanga fiɲɛ, ji ani sɔgɔli ma ni kemikɛli suguya caman ye.
A bɛnnen don sigida suguya caman ma: Nin fɛɛrɛ in b’a to a bɛnnen don kɛrɛnkɛrɛnnenya la ka kɛ sigida nɔgɔlenw na, kɛnɛma walima yɔrɔ minnu bɛ sɔgɔsɔgɔ, i n’a fɔ kurun minɛnw, kɛnɛma chassis, kumaɲɔgɔnya basigiyɔrɔw, a ɲɔgɔnnaw, wa a ka c’a la, furakɛli wɛrɛ tɛ kɛ ni electroplating anti-nɔgɔli ye.
3. Kuranko ɲuman ani magɛnni tɛ{1}}
Kuranko ɲuman : Aluminiyɔmu ye fɛn minɛta ɲuman ye, o la, aliminiyɔmu rivet nuts bɛ se ka kɛ cogoyaw la, kuran ɲɔgɔndanw ka kan ka kɛ yɔrɔ minnu na, walima ka u bila minɛnw kan minnu ka kan ka u yɛrɛ tanga static shielding walima interference ma walasa ka circuit ka tɛmɛsira sabati.

4. A sigili nɔgɔya ani a ka baara kɛ fan kelen-
Fiyentɔw dakun sirili fura: Nin ye rivet nuts nafa koloma ye. A bɛ se ka sigi ka bɔ fan kelen dɔrɔn na, wa a bɛnnen don kɛrɛnkɛrɛnnenya la pibilikiw, kɛsu walima baarakɛyɔrɔ datugulenw ma minnu bɛ se ka maga fan kelen dɔrɔn fɛ.
A sigili nafa ka bon kosɛbɛ: A sigili bɛ se ka ban joona ani ka da a kan ni marifa ye min bɛ kɛ ka riveting (bolola walima fiɲɛ), o bɛ kɛ kɔnɔna jiri jɔlen ye. Aluminiyɔmu ka nɔgɔn kosɛbɛ a kɛcogo la, o b’a to a bɛ nɔgɔya riveting deformation waati la ani a tɛ kɛ sababu ye ka baarakɛminɛnw sɛgɛn dɔɔnin.
5. Musaka-nafa sɔrɔli ani a waleyacogo
Galvanic corrosion balili : Ni a bilala aluminiyɔmu walima nɛgɛ wɛrɛw kan minnu seko ni dɔnko bɛ ɲɔgɔn ta (i n’a fɔ manje sɔgɔlenw), a bɛ se ka a yɛrɛ tanga kosɛbɛ kuran sɔgɔli ma (galvanic corrosion) min bɛ sɔrɔ nɛgɛw ni ɲɔgɔn cɛ minnu tɛ kelen ye, o bɛ dɔ bɔ musaka ni farati la ka fara insulasi furakɛli kan.
Nafolo ni waleyali: Ni i y’a suma ni nɛgɛ ye min tɛ sɔgɔ, a ka c’a la, aliminiyɔmu yɛrɛ musaka n’a baara musakaw ka dɔgɔ. Ni fanga ni nɔgɔya, sɔgɔsɔgɔninjɛ-kɛlɛli wajibiyalenw bɛ dafa, aliminiyɔmu sama rivet nuts bɛ fura di min musaka ka bon kosɛbɛ-.
