China OEM desturi shaba iliyopotea ntabidhaa za uwekezaji.
Shaba ni aloi inayojumuisha shaba na zinki. Shaba inayojumuisha shaba na zinki inaitwa shaba ya kawaida. Ikiwa ni aina mbalimbali za aloi zinazojumuisha vipengele zaidi ya mbili, inaitwa shaba maalum. Shaba ni aloi ya shaba na zinki kama nyenzo kuu. Wakati maudhui ya zinki yanapoongezeka, nguvu na plastiki ya alloy huongezeka kwa kiasi kikubwa, lakini sifa za mitambo zitapungua kwa kiasi kikubwa baada ya kuzidi 47%, hivyo maudhui ya zinki ya shaba ni chini ya 47%. Mbali na zinki, shaba iliyotupwa mara nyingi huwa na vitu vya aloi kama vile silicon, manganese, alumini na risasi.
Shaba ya kutupwa ina sifa ya juu ya mitambo kuliko shaba, lakini bei ni ya chini kuliko shaba. Mara nyingi shaba ya kutupwa hutumiwa kwa madhumuni ya jumla kubeba vichaka, vichaka, gia na sehemu na vali zinazostahimili kuvaa na sehemu nyingine zinazostahimili kutu. Shaba ina upinzani mkali wa kuvaa. Mara nyingi shaba hutumiwa kutengeneza valves, mabomba ya maji, mabomba ya kuunganisha kwa viyoyozi vya ndani na nje, na radiators.
