Njerwa zadothi lamoto ndi mtundu wapadera wa njerwa zopangidwa ndi dongo lamoto ndipo zimalimbana bwino ndi kutentha kwambiri zomwe zimagwiritsidwa ntchito mu ng'anjo, ng'anjo zamoto, poyatsira moto ndi mabokosi amoto. Njerwa zimenezi amazipanga mofanana ndi njerwa zomwe zili bwino.
Pokhapokha poyaka moto- Njerwa zamoto zimatentha kwambiri Kutentha kwa njerwa kumapitirira 1580ºC. Amagwiritsidwa ntchito makamaka ngati ng'anjo ya kaboni, ng'anjo yowotcha, ng'anjo yowotchera, ng'anjo yamagalasi, ng'anjo ya simenti, ng'anjo ya feteleza, ng'anjo yamoto, chitofu chowotcha, ng'anjo yophika, ng'anjo, kuponyera ndi kuponyera njerwa zachitsulo, etc.
Komanso, tili ndi njerwa zapamwamba za aluminiyamu zoti tisankhe. Ma aluminiyumu awo ndi apamwamba kuposa njerwa zadongo zamoto, ndipo kutentha kwake ndikwambiri. Ngati ng'anjo yanu ikufunika kutentha kwambiri komanso moyo wautali wautumiki, ndikuuzeni kuti musankhe njerwa za aluminiyamu.
Makhalidwe:
1.Kukana bwino kwa dzimbiri ndi abrasion.
2.Perfect kutentha kutentha kukana.
3.Good spalling kukana.
4.Mkulu mphamvu zamakina.
5.Kukhazikika kwa voliyumu yabwino pansi pa kutentha kwakukulu.
