Isahani y'umuringagukina ni umuringa ntushobora kubyara casting.Umuringa ukoreshwa cyane mubikorwa byo gukora imashini, amato, imodoka, ubwubatsi nizindi nzego zinganda, bikora urukurikirane rwumuringa mubikoresho bikomeye bidafite fer.Bikunze gukoreshwa bikozwe mu muringa ni amabati ya bronze, umuringa uyobora, icyuma cya Muntz na bronze ya aluminium.ingano yo kugabanuka kwa Cu-Sn alloy ni nto cyane (igipimo cyo kugabanuka kumurongo ni 1.45% kugeza 1.5%), kandi biroroshye gutanga ibicuruzwa bigoye hamwe nubukorikori hamwe nuburyo busobanutse bukeneye ibipimo nyabyo.Muri tin bronze idashobora kwambara, ibirimo fosifore usanga bingana na 1,2%.Zinc irashobora kunoza amazi ya alloy kandi ikagabanya gutandukanya gutandukanya amabati ya bronze.Isasu ritezimbere cyane kwambara no kurira hamwe na mashini ya alloy.Gukata amabati ya bronze akoreshwa nko kwambara no kwangirika kwangirika.Tin Fosifore Umuringa: Fosifore irashobora kuba deoxidizer nziza kumuringa wumuringa, ushobora kongera umuvuduko wamazi, kunoza imiterere yikoranabuhanga nubukanishi bwa tin bronze, ariko bikongerera urwego rwo gutandukana.Imipaka ntarengwa ya fosifore muri Hebei tin bronze ni 0.15%, niba irenze urugero, izakora α + δ + Cu3P ternary eutectic, ingingo yo gukonjesha ni 628 ℃, biroroshye gutanga ubukana bushyushye mugihe cyo kuzunguruka, bityo rero birashobora gukonja gusa.Kubwibyo, ibirimo fosifore mumabati yahinduwe amabuye ntibigomba kurenza 0.5%, niyo mpamvu fosifore igomba kuba ariko 0,25% mugihe cyo gukora gishyushye.Fosifore irimo amabati y'umuringa irashobora kuba ibikoresho bizwi cyane.Mugihe cyo gutunganya, birakenewe gucunga ingano yintete mbere yo gukora imbeho no gukonjesha nyuma yo kuyitunganya.Imbaraga, modulus ya elastique hamwe numunaniro imbaraga zibintu byiza-byuzuye birenze ibyo bikoresho byoroshye, ariko plastike iri hasi.Ibikoresho bikonje bikonjeshwa ku bushyuhe bwa kawa ya 200-260 ℃ mu masaha 1-2, biganisha ku gukomera no gukomera, bishobora kurushaho kunoza imbaraga, plastike, imipaka ya elastike na modulus ya elastique yibicuruzwa, kandi byongera ubuzima bwiza.Umuringa wa Tin-zinc: ingano nini ya zinc ishonga mu muringa-tin, bityo rero kongeramo zinc mu muringa wahinduwe amabuye ubusanzwe ni munsi ya 4%.Zinc irashobora kunoza amazi ya alloy, kugabanya ubushyuhe bwa kirisiti, no kugabanya gutandukana.
