eriri ọlanaeriri ọla kọpa ebute ụzọbụ ihe abụọ a na-ahụkarị ọla kọpa alloy ibe, isi ihe dị iche na-adabere na mejupụtara, arụmọrụ na ojiji.
Ⅰ Ihe mejupụtara
1. Bras bụ tumadi mejupụtara ọla kọpa (Cu) na zinc (Zn), na a nkịtị ruru nke 60-90% ọla kọpa na 10-40% zinc. Akara ndị nkịtị gụnyere H62, H68, wdg.
2. Brass na-edu ndú bụ ọla kọpa-zinc alloy na ụzọ (Pb) agbakwunyere, na ọdịnaya nke ndu na-abụkarị 1-3%. Na mgbakwunye na ndu, ọ nwekwara ike ịnwe obere ihe ndị ọzọ, dị ka ígwè, nickel ma ọ bụ tin, wdg. Mgbakwunye nke ihe ndị a nwere ike imeziwanye arụmọrụ nke alloy. Akara ndị nkịtị gụnyere HPb59-1, HPb63-3, wdg.
II. Njirimara arụmọrụ
1. Mechanical Njirimara
(1)Bras: Site na mgbanwe nke ọdịnaya zinc, ihe eji arụ ọrụ dị iche iche. Mgbe ọdịnaya zinc adịghị agafe 32%, ike na plasticity na-abawanye na mmụba nke ọdịnaya zinc; mgbe ọdịnaya zinc gafere 32%, plasticity na-adaba nke ọma, ike na-erute uru kachasị dị nso na zinc ọdịnaya nke 45%.
(2)Ọla na-eduga: Ọ nwere ike dị mma, na n'ihi ọnụnọ nke ndu, nkwụsi ike ya dị mma karịa nke ọla nkịtị.
2. Nhazi arụmọrụ
(1)Bras: Ọ nwere ezigbo plasticity na ike idi okpomọkụ na oyi nhazi, ma ọ bụ ngwa ngwa na-ajụ-okpomọkụ brittleness n'oge okpomọkụ nhazi dị ka forging, n'ozuzu n'etiti 200-700 ℃.
(2)Ọla na-eduga: Ọ nwere ike dị mma, na n'ihi ọnụnọ nke ndu, nkwụsi ike ya dị mma karịa nke ọla nkịtị. Ọnọdụ ndu n'efu na-eme ka ọ rụọ ọrụ na-ebelata esemokwu n'oge usoro esemokwu, nke nwere ike ibelata iyi.
3. Njirimara anụ ahụ na nke kemịkal
(1) Brass: Ọ nwere ezigbo conductivity eletriki, conductivity thermal na nguzogide corrosion. Ọ na-eji nwayọọ nwayọọ na-agbaze na ikuku, ọ dịghịkwa ngwa ngwa n'ime mmiri dị ọcha dị ọcha, ma ọ na-eresị ngwa ngwa n'ime mmiri oké osimiri. N'ime mmiri nwere ụfọdụ gas ma ọ bụ na gburugburu acid-base, ọnụ ọgụgụ corrosion ga-agbanwe.
(2) Brass na-edu: Igwe ọkụ eletrik na ọkụ ya dị ntakịrị ala karịa ọla, mana nguzogide corrosion ya yiri nke ọla. N'ebe ụfọdụ akọwapụtara, n'ihi mmetụta nke ndu, nguzogide corrosion ya nwere ike ịpụta nke ọma.
3. Ngwa
(1)Iberibe ọladị ukwuu vasatail na adabara a dịgasị iche iche nke oge, karịsịa ndị na-achọ ezi formability na elu àgwà.
1) Eletriki na eletriki ụlọ ọrụ: njikọ, ọnụ, mkpuchi mkpuchi, wdg.
2) Ihe ịchọ mma ụlọ: aka ọnụ ụzọ, ibe eji achọ mma, wdg.
3) N'ichepụta igwe: gaskets, isi iyi, ikpo ọkụ, wdg.
4) Ngwaike kwa ụbọchị: zippers, bọtịnụ, wdg.
(2)Iberibe ọla eduganwere arụmọrụ ịkpụ nke ọma ma dabara adaba maka ịrụ ọrụ nkenke, mana ekwesịrị itinye nlebara anya na gburugburu ebe obibi na ahụike nke ndu. N'ime usoro mmiri ọ drinkingụ drinkingụ na mpaghara nwere oke nchekwa gburugburu ebe obibi, a na-atụ aro ka iji eriri ọla na-enweghị ndu.
1) Akụkụ nkenke: akụkụ elekere, gia, valves, wdg.
2) Ngwa elektrọnik: njikọ njikọ dị elu, ọnụ, wdg.
3) Ụlọ ọrụ ụgbọ ala: akụkụ sistemu mmanụ, ụlọ ihe mmetụta, wdg.
