Tooj liab yog cov hlau qub tshaj plaws siv los ntawm tib neeg.Nws yog siv hnub rov qab mus rau lub sijhawm prehistoric.tooj liab tau raug mined rau ntau tshaj 10,000 xyoo nrog ib tug tooj liab pendant pom nyob rau hauv niaj hnub Iraq yog hnub tim rau 8700BC.Los ntawm 5000BC Copper tau raug smelted los ntawm yooj yim tooj liab Oxides.Tooj liab yog pom nyob rau hauv haiv neeg hlau thiab nyob rau hauv cov minerals cuprite, malachite, azurite, chalcopyrite thiab bornite.
Nws kuj yog feem ntau yog los ntawm cov khoom siv nyiaj ntau lawm.Sulphides, oxides thiab carbonates yog cov ore tseem ceeb tshaj plaws.Copper thiab tooj liab alloys yog qee yam khoom siv engineering uas muaj ntau yam.Kev sib xyaw ua ke ntawm lub cev muaj zog xws li lub zog, conductivity, corrosion resistance, machinability thiab ductility ua tooj liab haum rau ntau yam kev siv.Cov khoom no tuaj yeem txhim kho ntxiv nrog kev hloov pauv hauv kev sib xyaw thiab kev tsim khoom.
Kev lag luam hauv tsev
Qhov loj tshaj plaws kawg siv rau tooj liab yog nyob rau hauv lub tsev kev lag luam.Hauv kev lag luam hauv tsev, kev siv cov khoom siv tooj liab yog dav.Kev tsim kho kev lag luam ntsig txog daim ntawv thov rau tooj liab suav nrog:
vov tsev
Cladding
Rainwater systems
Cua sov tshuab
Cov kav dej thiab fittings
Roj thiab roj kab
Hluav taws xob thaiv
Kev lag luam hauv tsev yog cov neeg siv khoom loj tshaj plaws ntawm tooj liab alloy.Cov npe hauv qab no yog kev sib cais ntawm kev siv tooj liab los ntawm kev lag luam txhua xyoo:
Kev lag luam hauv tsev - 47%
Cov khoom siv hluav taws xob - 23%
Kev thauj mus los - 10%
Cov khoom siv - 11%
Kev lag luam tshuab - 9%
Commercial Compositions ntawm tooj liab
Muaj nyob ib ncig ntawm 370 kev lag luam sib xyaw rau tooj liab alloy.Qib feem ntau yog C106 / CW024A - tus qauv dej raj qib tooj liab.
Ntiaj teb kev siv tooj liab thiab tooj liab alloy tam sim no tshaj 18 lab tonnes ib xyoos twg.
Kev siv tooj liab
Copper thiab tooj liab alloy tuaj yeem siv rau hauv ntau yam kev siv tshwj xeeb.Qee qhov kev thov no suav nrog:
Fais fab kis kab
Architectural applications
Cov tais diav
Spark plugs
Hluav taws xob thaiv, cables thiab busbars
High conductivity hlau
