Izi ndizodziwika bwino mumakampani amagetsi.Zida za waya wamkuwa ndi waya wa aluminiyamu ndizosiyana ndipo mankhwala ake ndi osiyana.Chifukwa mkuwa ndi aluminiyamu zimakhala ndi kuuma kosiyana, kulimba kwamphamvu, kunyamula kwapano, ndi zina zotere, ngati mawaya amkuwa ndi aluminiyamu amalumikizana mwachindunji,

1. Pakhoza kukhala chiwopsezo cha kulumikizidwa chifukwa cha kulephera kwamphamvu kwamphamvu, makamaka ngati mizere yopitilira pamwamba ikugwiritsidwa ntchito.

2. Kupatsa mphamvu kwa nthawi yaitali kumayambitsa machitidwe a mankhwala, okosijeni wazitsulo zamkuwa-aluminium, kuwonjezeka kwa kukana pazitsulo zamkuwa-aluminium, ndi kutentha, zomwe zingayambitse ngozi za chitetezo monga moto pazovuta kwambiri.

3. Mphamvu yonyamula pano ndi yosiyana.Waya wofanana ndi waya wamkuwa ndi 2 mpaka 3 kuposa wa waya wa aluminiyamu.Waya wamkuwa wa aluminiyamu ungakhudze mwachindunji mphamvu yonyamula pakali pano ya mzerewu.Ndiye momwe mungalumikizire waya wamkuwa ndi waya wa aluminiyamu kuti akhale otetezeka komanso odalirika?

Nthawi zambiri, zolumikizira zamkuwa ndi aluminiyamu zimagwiritsidwa ntchito kwambiri pomanga mzere.Cholumikizira chosinthira chamkuwa ndi aluminiyamu chimakhala choyenera pomanga mzere waung'ono.
