ọla kọpa alloy

A na-emepụta alloy ọla kọpa site n'ịgbakwụnye ụfọdụ ihe ndị na-eme ka alloy (dị ka zinc, tin, aluminum, beryllium, manganese, silicon, nickel, phosphorus, wdg) na ọla kọpa dị ọcha.Alloys ọla kọpa nwere ezigbo ọkụ eletrik, conductivity thermal and corrosion resistance, yana ike dị elu ma na-eyi nguzogide.

Dabere na ihe mejupụtara, a na-ekewa alloys ọla kọpa na ọla na ọla.

1. Brass bụ ọla kọpa na zinc dị ka isi ihe na-emepụta ihe.Dị ka ihe mejupụtara kemịkalụ si dị, a na-ekewa ọla n'ime ọla kọpa nkịtị na ọla pụrụ iche.

(1) Brass nkịtị bụ ọla kọpa-zinc ọnụọgụ abụọ alloy.N'ihi ịdị mma ya dị mma, ọ dị mma maka ịmepụta efere, ogwe, wires, ọkpọkọ na akụkụ dị omimi, dị ka ọkpọkọ condenser, ọkpọkọ jụrụ oyi na ígwè na eletriki.Brass nwere nkezi ọdịnaya ọla kọpa nke 62% na 59% nwekwara ike nkedo ma kpọọ ya nkedo ọla.

(2) Brass pụrụ iche iji nweta ike dị elu, nguzogide corrosion na ịrụ ọrụ nkedo dị mma, aluminom, silicon, manganese, lead, tin na ihe ndị ọzọ na-agbakwunye na ọla kọpa-zinc alloy iji mepụta ọla pụrụ iche.Dị ka ọla isi, tin brass, aluminum brass, silicon brass, manganese brass, wdg.

Ngwongwo ọla nwere ọmarịcha arụmọrụ dị mma na nguzogide dị mma, a na-ejikwa ya n'ichepụta akụkụ elekere, a na-atụbakwa ya iji mee bushes na bushes.

Tin brass nwere ezigbo nguzogide corrosion ma na-eji ya eme ihe n'ịrụ akụkụ nke ụgbọ mmiri.

Aluminom dị na ọla kọpa aluminom nwere ike imeziwanye ike na ike nke ọla ma melite nguzogide corrosion ya na ikuku.A na-eji ọla kọpa aluminom na-emepụta akụkụ na-eguzogide corrosion.

Silicon na silicon ọla nwere ike melite n'ibu Njirimara, eyi iguzogide na corrosion iguzogide nke ọla kọpa.A na-ejikarị ọla kọpa silicon emepụta akụkụ mmiri na akụkụ igwe kemịkalụ.

ọla kọpa

Bronze na mbụ na-ezo aka ọla kọpa-tin alloy, ma ụlọ ọrụ na-eji na-akpọ ọla kọpa alloys nwere aluminum, silicon, lead, beryllium, manganese, wdg nakwa ọla, otú ọla n'ezie gụnyere tin bronze, aluminum bronze, aluminum bronze, beryllium ọla. ọla kọpa silicon, ọla kọpa, wdg. A na-ekekwa ọla nchara ụzọ abụọ: ọla kọpa na-arụ ọrụ na nkedo ọla.

(1) Tin bronze Alloy dabeere ọla kọpa nwere tin dị ka isi alloy element a na-akpọ tin bronze.Ọtụtụ n'ime bronze a na-eji na ụlọ ọrụ nwere ihe dị n'etiti 3% na 14%.Tin bronze nke nwere ihe na-erughị 5% kwesịrị ekwesị maka ịrụ ọrụ oyi;tin bronze nke nwere ọdịnaya nke 5% ruo 7% kwesịrị ekwesị maka ịrụ ọrụ ọkụ;tin bronze nwere ihe nwere ihe karịrị 10% dị mma maka nkedo.A na-eji bronze agba agba eme ihe n'ọtụtụ ebe n'ịrụ ụgbọ mmiri, ụlọ ọrụ kemịkalụ, igwe, akụrụngwa na ụlọ ọrụ ndị ọzọ.A na-ejikarị emepụta akụkụ ndị na-eguzogide iyi dị ka bearings na bushings, ihe na-agbanwe dị ka isi iyi, na mgbochi corrosion na mgbochi magnetik.

(2) Aluminom ọla kọpa alloy dabeere ọla na aluminum dị ka isi alloying element a na-akpọ aluminum bronze.Ihe eji arụ ọrụ nke ọla kọpa aluminom dị elu karịa nke brass na tin bronze.Ọdịnaya aluminom nke ọla aluminom bara uru dị n'etiti 5% na 12%, na ọla kọpa aluminom nwere ọdịnaya aluminom nke 5% ruo 7% nwere plastik kacha mma ma dabara adaba maka ịrụ ọrụ oyi.Mgbe ọdịnaya aluminum karịrị 7% ruo 8%, ike na-abawanye, ma plasticity na-ebelata nke ọma, ya mere a na-ejikarị ya na steeti nkedo ma ọ bụ mgbe ọ na-arụ ọrụ ọkụ.Nguzogide abrasion na nguzogide corrosion nke aluminom bronze na ikuku, mmiri mmiri, mmiri mmiri carbonic acid na ọtụtụ organic acid dị elu karịa nke ọla na tin bronze.Aluminom bronze nwere ike rụpụta ngwo, bushings, worm gears na ndị ọzọ na-ike ike eyi na-eguzogide akụkụ na na-agbanwe ihe na elu corrosion eguzogide.

(3) Ọla ọla kọpa nwere beryllium dị ka ihe bụ isi ka a na-akpọ beryllium bronze.Ọdịnaya beryllium nke bronze beryllium bụ 1.7% ruo 2.5%.Bronze Beryllium nwere oke ngbanwe dị elu na oke ike ọgwụgwụ, ezigbo mgbochi iyi na nguzogide corrosion, ezigbo eletriki eletriki na conductivity thermal, ma nweekwa uru nke na-abụghị magnetik, enweghị ọkụ mgbe ọ metụtara.A na-ejikarị beryllium bronze mee isi iyi dị mkpa maka ngwá ọrụ ziri ezi, mgbanaka elekere, bearings na bushings na-arụ ọrụ n'okpuru nnukwu ọsọ na nrụgide dị elu, yana igwe eletrik eletrik, ihe mgbawa na-agbawa agbawa, compasses mmiri na akụkụ ndị ọzọ dị mkpa.
