Ọla kọpa, Brass na Bronze, nke a na-akpọ "Red Metals", nwere ike ịdị otu ihe na mbụ mana ha dị nnọọ iche.
Ọla kọpa
A na-eji ọla kọpa mee ihe n'ọtụtụ ngwaahịa n'ihi ọmarịcha ọkụ eletrik na ọkụ ọkụ, ike dị mma, ọdịdị dị mma na iguzogide corrosion. A na-ejikarị ọla ndị a na-emepụta ọkpọkọ na ọkpọkọ n'ihi nguzogide corrosion ha. Enwere ike ire ha ngwa ngwa na brazed, ọtụtụ nwere ike ịgbanye ha site na gas dị iche iche, arc na ụzọ mgbochi. Enwere ike ịchacha ha ma mee ka ọ bụrụ ihe fọrọ nke nta ka ọ bụrụ ụdị ọ bụla achọrọ.
Enwere akararị ọla kọpa na-adịghị mma, ha nwere ike ịdịgasị iche na oke adịghị ọcha dị n'ime ya. A na-eji akara ọla kọpa na-enweghị oxygen eme ihe kpọmkwem na ọrụ ebe a chọrọ nnukwu conductivity na ductility.
Otu n'ime ihe kachasị mkpa nke ọla kọpa bụ ikike ya ịlụso nje bacteria ọgụ. Mgbe ọtụtụ nyocha nke antimicrobial nke ụlọ ọrụ na-ahụ maka gburugburu ebe obibi nyochachara, a chọpụtara na 355 ọla kọpa alloys, gụnyere ọtụtụ brasses, na-egbu ihe karịrị 99.9% nke nje bacteria n'ime awa abụọ kọntaktị. Achọpụtara ntọrị nkịtị ka ọ ghara imebi irè ọgwụ nje.
Ngwa ọla kọpa
Ọla kọpa bụ otu n'ime ọla ndị mbụ achọpụtara. Ndị Gris na ndị Rom mere ya ka ọ bụrụ ngwá ọrụ ma ọ bụ ihe ịchọ mma, na e nwere ọbụna nkọwa akụkọ ihe mere eme na-egosi ntinye ọla kọpa iji mee ka ọnyá kwụsị ma mee ka mmiri ọṅụṅụ dị ọcha. Taa, a na-ahụkarị ya na ngwa eletriki dị ka wiring n'ihi ike ya na-eduzi ọkụ eletrik nke ọma.
Bras
Brass bụ ọkachasị alloy nwere ọla kọpa yana zinc agbakwunyere. Brasses nwere ike ịnwe zinc dị iche iche ma ọ bụ ihe ndị ọzọ agbakwunyere. Ngwakọta ndị a dị iche iche na-emepụta ihe dị iche iche nke ihe onwunwe na mgbanwe dị iche iche na agba. Mmụba nke zinc na-enye ihe ahụ ike na ductility dị mma. Brass nwere ike ịdị na agba site na ọbara ọbara ruo odo dabere na ọnụọgụ zinc agbakwunyere na alloy.
- Ọ bụrụ na ọdịnaya zinc nke brass sitere na 32% ruo 39%, ọ ga-abawanye ikike ịrụ ọrụ ọkụ mana ọrụ oyi ga-adị oke.
- Ọ bụrụ na ọla ahụ nwere ihe karịrị 39% zinc (ihe atụ - Muntz Metal), ọ ga-enwe ike dị elu na obere ductility (na ọnụ ụlọ okpomọkụ).
Ngwa Brass
A na-ejikarị brass eme ihe ịchọ mma n'ihi na ọ dị ka ọla edo. Ọ bụkwa ihe a na-ejikarị eme ngwa egwu n'ihi oke ọrụ ya na ịdịte aka ya.
Alloys Brass ndị ọzọ
Tin Brass
Nke a bụ alloy nwere ọla kọpa, zinc na tin. Otu alloy a ga-agụnye brass admiralty, brass naval na brass machining free. Agbakwunyela tin ahụ iji gbochie dezincification (mwepu nke zinc site na alloys brass) n'ọtụtụ gburugburu. Otu a nwere mmetụta dị ala na dezincification, ike na-agafeghị oke, ikuku dị elu na nguzogide corrosion nke mmiri na ezigbo ọkụ eletrik. Ha nwere ezigbo ọkụ forgeability na ezigbo oyi formability. A na-ejikarị alloys ndị a na-emepụta ngwakọ, ngwaike mmiri, akụkụ igwe ịghasa, ogwe mgbapụta na ngwaahịa na-eguzogide corrosion.
Ọla
Bronze bụ alloy nke mejupụtara isi ọla kọpa yana mgbakwunye nke ihe ndị ọzọ. N'ọtụtụ ọnọdụ, ihe a na-agbakwunye na-abụkarị tin, mana arsenic, phosphorus, aluminum, manganese, na silicon nwekwara ike iji mepụta ihe dị iche iche na ihe ahụ. Ihe ndị a niile na-emepụta alloy siri ike karịa ọla kọpa naanị.
A na-eji agba ọla edo mara ọla kọpa. Ị nwekwara ike ịmata ọdịiche dị n'etiti ọla kọpa na ọla n'ihi na ọla kọpa ga-enwe mgbanaka na-esighị ike n'elu ya.
Ngwa ọla kọpa
A na-eji ọla kọpa na-arụ ihe ọkpụkpụ, ngwa egwu na ihe nrite, na ngwa mmepụta ihe dị ka bushes na bearings, ebe ígwè ya dị ala na esemokwu ígwè bụ uru. Bronze nwekwara ngwa mmiri n'ihi na ọ na-eguzogide corrosion.
Alloy Bronze ndị ọzọ
Bronze phosphor (ma ọ bụ Tin Bronze)
Alloy a na-enwekarị ọdịnaya tin sitere na 0.5% ruo 1.0%, yana phosphorous nso nke 0.01% ruo 0.35%. Alloys ndị a bụ ndị ama ama maka ike ha siri ike, ike ha, ọnụ ọgụgụ dị ala nke esemokwu, oke ike ọgwụgwụ, na ezigbo ọka. Ọdịnaya tin na-abawanye nguzogide corrosion na ike ntakiri, ebe ọdịnaya phosphorous na-abawanye nguzogide iyi na isi ike. Ụfọdụ ihe eji eme njedebe maka ngwaahịa a ga-abụ ngwaahịa eletriki, mgbịrịgba, isi iyi, ihe ncha, akụrụngwa na-eguzogide corrosion.
Aluminom Bronze
Nke a nwere ọnụọgụ aluminom nke 6% - 12%, ọdịnaya ígwè nke 6% (max), yana ọdịnaya nickel nke 6% (max). Ihe mgbakwunye ndị a jikọtara ọnụ na-enye ike dị ukwuu, jikọtara ya na nguzogide dị mma na corrosion na iyi. A na-ejikarị ihe a na-emepụta ngwaike mmiri, aka aka aka na nfuli ma ọ bụ valvụ na-ejikwa mmiri na-emebi emebi.
Silicon Bronze
Nke a bụ ihe alloy nwere ike ikpuchi ma ọla na ọla (ọla silicon na-acha uhie uhie na ọla silicon na-acha uhie uhie). Ha na-enwekarị 20% zinc na 6% silicon. Brass na-acha uhie uhie nwere ike dị elu na nguzogide corrosion ma na-ejikarị ya eme ihe maka valvụ. Bronze na-acha uhie uhie yiri nke a mana o nwere obere zinc. A na-ejikarị ya eme ihe n'ichepụta ihe mgbapụta na valvụ.
Nickel Brass (ma ọ bụ ọlaọcha nickel)
Nke a bụ alloy nwere ọla kọpa, nickel na zinc. Nickel na-enye ihe ahụ ihe fọrọ nke nta ka ọ bụrụ ọlaọcha. Ihe a nwere ike na-agafeghị oke na ezigbo nguzogide corrosion. A na-ejikarị ihe a na-emepụta ngwa egwu, ihe oriri na ihe ọṅụṅụ, ngwa anya, na ihe ndị ọzọ ebe mma bụ ihe dị mkpa.
Nickel ọla kọpa (ma ọ bụ Cupronickel)
Nke a bụ alloy nwere ike ịnwe ebe ọ bụla site na 2% ruo 30% nickel. Ihe a nwere oke nrụrụ-eguzogide ma nwee nkwụsi ike nke okpomọkụ. Ihe a na-egosipụtakwa nnabata dị oke elu maka mgbawa corrosion n'okpuru nrụgide na oxidation na uzuoku ma ọ bụ ikuku ikuku. Ọdịnaya nickel dị elu n'ihe a ga-emeziwanye nguzogide corrosion na mmiri oke osimiri, yana iguzogide mmetọ ndu mmiri. A na-ejikarị ihe a na-emepụta ngwaahịa eletrọnịkị, akụrụngwa mmiri, valvụ, nfuli na ụgbọ mmiri.
