Àkwà mmiri aluminom nke oge a, 90% nke ihe bụ profaịlụ extrusion 6061, karịsịa maka okporo ụzọ eji. Ngwa aluminom na-agafe agafe bụ nke aluminom alloy 6063. 6061 alloy bụ AI-Mg-Si-Cu-Cr usoro alloy nke mepụtara Alcoa ụlọ ọrụ na 1933. Ọ bụ otu n'ime anọ inogide, kpochapụwo, azụmahịa okpomọkụ ọgwụgwọ alloys. (The anọ okpomọkụ ọgwụgwọ ike alloys na-gụnyere 2024, 6061,6063,7075 usoro alloy.) The mmepụta nke 6061 alloy bụ ubé na-erughị 6063, ma ụzọ karịa 2024 na 7075 usoro alloy.

 

 

 

Ruo Dec nke 2019, 6061 usoro ezinụlọ nwere 5 òtù, ma e wezụga 6061A bụ e mepụtara EAA, ndị ọzọ bụ American alloy, biko rụtụ aka Form 1 maka chemical components.

Na mmepe àkwà mmiri aluminom, e wuru nke mbụ na Smithfield St, Pittsburgh, Steeti. Ọ bụ 100m na ​​okporo ụzọ elu e mere nke 2014-T6 oké aluminum alloy efere, wuru na 1933. Ọ na-ewusi na 1967 na-anọchi ike corrosion eguzogide oké aluminum alloy efere 5456-H321. A na-ekwukwa na tupu 1953, ọtụtụ aluminom àkwà mmiri bụ nke 2014-T6 usoro alloy. British Hendon jiri 2014-T6 usoro alloy na ụfọdụ 6151-T6 usoro nnukwu aluminom akwa akwa mbụ. A akwa n'elu Tummel River na Scotland nke ji 6151-T6 usoro alloy mkpa aluminum efere e wuru na 1950. Tupu 1962 (1953-1962), ụfọdụ àkwà mmiri na Germany na Britain e ji 6351-T6 usoro alloy mkpa aluminum ripples.

 

 

 

Site n'etiti 90s, 6061-T6 usoro alloy profaịlụ nwere a na-achị ọnọdụ na àkwà mmiri structural ihe. Ọdọ mmiri aluminom kacha dị ịrịba ama na ama ama bụ nke e wuru n'elu Osimiri Juniata na steeti Pennsylvania.
