Otú ọ dị, e jiri ya tụnyere 6000 usoro aluminum alloy (nke na-eji magnesium na silicon dị ka isi ihe na-emepụta ihe na-arụ ọrụ na-arụ ọrụ nke ọma), usoro 7000 aluminum alloy na-esiwanye ike ịhazi ma na-achọ ngwa nhazi na nhazi usoro. N'ihe gbasara ịgbado ọkụ, 7000 usoro aluminum alloy nwere adịghị mma weldability. N'oge usoro ịgbado ọkụ, ntụpọ dị ka mgbawa na pores nwere ike ime, na-eme ka a na-eji usoro ịgbado ọkụ pụrụ iche na ihe nkpuchi iji hụ na ịdị mma nke nkwonkwo welded.
II. Usoro ọgwụgwọ okpomọkụ
Arụmọrụ nke 7000 usoro aluminum alloy na-adabere n'ụzọ dị ukwuu na okpomọkụ ọgwụgwọ usoro. Usoro ọgwụgwọ okpomọkụ a na-ahụkarị gụnyere ọgwụgwọ ngwọta, nkwụsịtụ, na ọgwụgwọ ịka nká.
Ọgwụgwọ Ngwọta
The 7000 usoro aluminum alloy na-ekpo ọkụ na a ụfọdụ okpomọkụ ka n'ụzọ zuru ezu igbari ike n'ụzọ na matriks, na-akpụ a edo siri ike ngwọta. Usoro a nwere ike imeziwanye plasticity na ike siri ike nke alloy, na-atọ ntọala maka ọgwụgwọ ịka nká na-esote. Okpomọkụ na oge ọgwụgwọ ọgwụgwọ kwesịrị ịchịkwa nke ọma iji hụ na agbazere usoro ndị na-ewusi ike nke ọma na iji zere ntụpọ dị ka oke ọkụ.
