A zabwinochimango cha njingaayenera kukwaniritsa zinthu zitatu za kulemera kwa kuwala, mphamvu zokwanira ndi kukhazikika kwakukulu.Monga masewera anjinga, chimango ndicholemera
Kupepuka kumakhala bwinoko, kulimbikira kochepa kumafunika komanso kukwera mwachangu:
Mphamvu zokwanira zikutanthauza kuti chimango sichidzathyoledwa ndi kupindika pansi pa kukwera kwamphamvu kwambiri;
Kukhazikika kwakukulu kumatanthawuza kukhazikika kwa chimango.Nthawi zina chimango chokhala ndi kusakhazikika bwino sichingakhale ndi nkhawa zachitetezo, koma mphamvu ya chimango imafalikira pokwera.
Kusiyana kwa kalozera kumapangitsa wokwerayo kumva ngati njinga ikukoka poyiponda.Ngakhale chimango ndi chopepuka komanso champhamvu mokwanira, koma kusasunthika kumakhala koyipa, ndi chinthu chimodzi.
Njinga yamasewera yotsika.Mwa mitundu yamagalimoto pamsika, zida za chimango zomwe zimatha kukwaniritsa zomwe zatchulidwa pamwambapa ndi: aluminium alloy,
Pali mitundu inayi ya carbon fiber, titaniyamu alloy ndi alloy steel.

1. Aloyi zitsulo zakuthupi:
Chitsulo ndiye chimango chachikhalidwe cha njinga.Mitundu yosiyanasiyana yazitsulo zamakono zamakono zingagwiritsidwe ntchito mokhazikika, kusungunuka, kufalitsa ndi kukhazikika.
Zotsatira zabwino zimapezeka.Choyipa chokha ndi chakuti kulemera kwa t kwachitsulo ndi cholakwika, ndipo kulemera kwake kumakhala kolemera kuposa t chiwerengero cha zipangizo.-Nthawi zambiri, chitsulo cha alloy
Mtengo wazinthu ndi wotsika mtengo.Komabe, mtengo wabwino wachitsulo chopangidwa ndi chitsulo ndi chitsulo cha molybdenum sizotsika mtengo.
Zinthu zakuthupi tingaziyerekezere.

2.Aluminiyamu alloy:
Mphamvu ya aluminiyamu ya alloy ndi yovuta, yopepuka, yopepuka, komanso yolimba kwambiri, koma nthawi yomweyo imaperekanso kuyankha kwa kugwedezeka kwa mfundo iliyonse ya J pansi.
Chitonthozo chimaperekedwa nsembe pang'ono.Zotsika mtengo komanso pali masitaelo ambiri a chimango, ndimitundu yosiyanasiyana yomwe imayenera kugulidwa ndi aliyense.

3. Carbon fiber:
Makhalidwe a carbon fiber: elasticity, kumverera kosasunthika, kuyenda kwamtunda wautali, komanso kutonthozedwa kwakukulu.Choyipa ndichakuti mtengo wake ndi wokwera kwambiri, ndipo ine
Avereji ya moyo wautumiki (wowerengedwa kuchokera ku fakitale) ndi zaka 5 kapena 6 zokha.Ngakhale pasanathe zaka 6 palibe kugunda mu chimango, mankhwala ake akadali akadali
E yawonongeka, ndipo sikulimbikitsidwa kuti okwera apitirize kuigwiritsa ntchito.

4. Titaniyamu aloyi:
Makhalidwe a titaniyamu aloyi ndi ofanana kwambiri ndi kuphatikiza kwa aluminiyamu aloyi ndi mpweya CHIKWANGWANI.Itha kukhala ndi elasticity yofanana ndi kaboni fiber komanso imatha kusangalala ndi aloyi ya aluminiyamu.
Kupepuka kwake ndi kukhazikika kwake.Mfundo yake yapadera ndi chifukwa cha kudumpha kwa coefficient yowonjezera, zomwe zimapangitsa kuti zikhale zosatheka kujambula pazitsulo, koma mwamwayi titaniyamu alloy.
Sikophweka corrode ndi oxidize, ndipo mtundu ndi wapadera.Koma mtengo wake sufanananso ndi atatu oyambirira.
