1. Electrochemical corrosion: Kɔbere ne aluminium tumi fa electrochemical corrosion mu wɔ mframa mu. Sɛ wohyia, titiriw wɔ baabi a ɛhɔ yɛ nwini a, aluminium yɛ adwuma sɛ electrode a enye .
Nkyene ba, na kɔbere yɛ electrode a ɛyɛ papa, na ɛma aluminum waya no fã a ɛwɔ nkwaa no nsɛe nkakrankakra na ɛma nkitahodi a ɛko tia no yɛ kɛse.
Nea ɛto so abien, nsonsonoe a ɛwɔ resistivity mu: kɔbere resistivity no sua sen aluminium de no, a ɛkyerɛ sɛ kɔbere waya no wɔ resistance ketewaa bi na ɛyɛ anyinam ahoɔden a ɛkɔ so yiye wɔ tebea koro no ara mu. Bere a kɔbere waya ne aluminum waya no abɔ mu tẽẽ .
Sɛ ɛka bom a, esiane resistivity soronko nti, resistance a ɛwɔ connection point no bɛkɔ soro.
Mmiɛnsa, Ɔhyew mu ntrɛwmu nsusuwii ahorow: Kɔbere ne aluminium wɔ ɔhyew ntrɛwmu nsusuwii ahorow, a ɛkyerɛ sɛ ɛtrɛw kodu digrii ahorow so bere a ɔhyew no sesa no, na eyi betumi de ɔhaw ahorow aba wɔ nkitahodi mmeae no .
Wɔma nsonsonoe ba, na ɛnam so ma nkitahodi a ɛko tia no yɛ kɛse.
