Brass nkịtị

Ọla isi
Lead bụ n'ezie insoluble na ọla ma na-ekesa na ọka ókè na steeti free ahụ.Dị ka nzukọ ya si kwuo, ọla kọpa nwere ụdị abụọ: α na (α+β).N'ihi mmetụta ọjọọ nke lead, ọla alfa-lead nwere plasticity dị elu dị ala nke ukwuu, yabụ na ọ nwere ike bụrụ naanị nrụrụ oyi ma ọ bụ kpochapụ ọkụ.(α+β) Ọla kọpa nwere ezigbo plasticity na oke okpomọkụ ma enwere ike imepụta ya.

Tin ọla
Ịtinye tin na ọla nwere ike ime ka okpomọkụ dị elu nke alloy dịkwuo mma, karịsịa ikike iguzogide corrosion nke mmiri mmiri, ya mere a na-akpọ tin brass "navy brass".
Tin nwere ike igbari n'ime ihe ngwọta siri ike dabere na ọla kọpa ma kpọọ mmetụta siri ike na-ewusi ike.Ma na mmụba nke tin ọdịnaya, brittle r-phase (CuZnSn compound) ga-apụta na alloy, nke na-adịghị akwado nrụrụ plastik nke alloy, yabụ ọdịnaya tin nke tin brass na-adịkarị na nso 0.5% ruo 1.5%
Tin brass ndị a na-ejikarị bụ HSn70-1, HSn62-1, HSn60-1 na ndị ọzọ.Nke mbụ bụ alfa alloy, nke nwere nnukwu plasticity na enwere ike ịhazi ya site na oyi na ọkụ ọkụ.Alloys nke ikpeazụ nke abụọ akara ule nwere a (α + β) usoro nke abụọ, na obere ego nke r-phase na-emekarị, na plasticity na ụlọ okpomọkụ adịghị elu, na ọ nwere ike na-emezi naanị na ọkụ. steeti.

Manganese Brass
Manganese nwere nnukwu solubility na bras siri ike.Ịgbakwunye 1% na 4% nke manganese na ọla nwere ike ịbawanye ike na nguzogide corrosion nke alloy na-ebelata ike ya.
Brass manganese nwere usoro (α + β), na HMn58-2 na-ejikarị eme ihe, na arụmọrụ nhazi nrụgide ya n'okpuru ọnọdụ oyi na ọkụ dị mma.

Igwe ọla kọpa
Na ọla kọpa ígwè, ígwè na-ebuli ya na ihe ndị na-emepụta ihe na-emepụta ígwè, nke na-eje ozi dị ka kristal kristal iji nụchaa ọka kristal ma gbochie uto nke mkpụrụ osisi recrystallized, si otú ahụ na-eme ka ihe ndị na-arụ ọrụ na-arụ ọrụ na nhazi nke alloy.Ihe dị n'ime ígwè dị na bras ígwè na-adịkarị n'okpuru 1.5%, nhazi ya bụ (α + β), ọ nwere ike dị elu na ike siri ike, plasticity dị mma na okpomọkụ dị elu, enwere ike ịmegharị ya na ọnọdụ oyi.Ọkwa a na-ejikarị bụ Hfe59-1-1.

Nickel ọla
Nickel na ọla kọpa nwere ike ịmepụta ngwọta siri ike na-aga n'ihu, nke na-agbasawanye mpaghara α-phase nke ukwuu.Mgbakwunye nke nickel na ọla nwere ike imeziwanye nguzogide corrosion nke bras na ikuku na mmiri mmiri.Nickel nwekwara ike ịbawanye okpomọkụ recrystallization nke ọla ma kwalite nguzobe nke ọka ndị ka mma.
HNi65-5 nickel brass nwere otu usoro α, nke nwere ezigbo plasticity na ụlọ okpomọkụ ma nwee ike imebi ya n'okpuru ọnọdụ ọkụ.Otú ọ dị, a ghaghị ịchịkwa ọdịnaya nke ndu adịghị ọcha nke ọma, ma ọ bụ na ọ ga-emebi nke ọma ọrụ ọkụ nke alloy.
