Ka'idodin injina na kayan gami na titanium[1-3]
A cikin tsarin aikin injiniya, kayan aikin da aka zaɓa, yanayin yankewa da yanke lokaci zai shafi tasiri da tattalin arziki na yankan alloy titanium.
1. Zaɓi kayan aiki mai ma'ana
Bisa ga kaddarorin, hanyoyin sarrafawa da kuma sarrafa yanayin fasaha na kayan haɗin gwal na titanium, kayan aikin kayan aiki ya kamata a zaba da kyau.Ya kamata a zaɓi kayan aikin da aka fi amfani da su, ƙarancin farashi, juriya mai kyau, ƙarfin zafi mai ƙarfi, kuma yana da isasshen ƙarfi.
