Tooj liab yog ib qho ntawm ntau yam thiab siv dav hlau hauv kev lag luam, khoom plig rau nws cov hluav taws xob zoo thiab thermal conductivity, corrosion kuj, thiab ua haujlwm. Ntawm ntau yam tooj liab alloys, phosphorus-deoxidized tooj liab-tshwj xeeb tshaj yogTP1 (C12000)thiabTP2 (C12200)-yog qhov tseem ceeb hauv cov ntawv thov xws li cov kav dej thiab HVAC rau hluav taws xob engineering thiab cov khoom siv hluav taws xob. Thaum lawv sib koom ntau qhov sib xws, lawv qhov sib txawv hauv kev sib xyaw, cov khoom, thiab kev siv yog qhov tseem ceeb. Kab lus no tshawb txog qhov sib txawv no los pab engineers, designers, thiab procurement specialists txiav txim siab paub.
Tshuaj muaj pes tsawg leeg
| Element | TP1 (C12000) | TP2 (C12200) |
|---|---|---|
| Cu + Ag | Ntau dua lossis sib npaug li 99.9% | Ntau dua lossis sib npaug li 99.9% |
| P | 0.004% – 0.012% | 0.015% – 0.040% |

TP1 (Low Residual Phosphorus):
Nrog cov ntsiab lus phosphorus tswj ntawm 0.004% thiab 0.012%, TP1 khaws cov hluav taws xob ntau dua thiab thermal conductivity. Qib qis phosphorus zoo deoxidizes tooj liab yam tsis muaj cuam tshuam cov electron txaus.
TP2 (Higher Residual Phosphorus):
TP2 muaj 0.015% rau 0.040% phosphorus, uas muab kev txhim kho deoxidization. Qhov no ua rau nws tshwj xeeb tshaj yog haum rau vuam thiab brazing tab sis me ntsis txo conductivity piv rau TP1.
Kev sib piv tseem ceeb
Hluav taws xob thiab Thermal conductivity
TP1 muaj hluav taws xob conductivity ntawm kwv yees li 85% IACS (International Annealed Copper Standard), ua kom nws zoo dua rau cov kev siv uas conductivity yog qhov tseem ceeb, xws li hluav taws xob busbars, connectors, thiab tshav kub exchangers.
TP2 muaj nyob ib ncig ntawm 80% IACS vim nws cov ntsiab lus phosphorus ntau dua. Txawm hais tias tseem muaj kev coj ua zoo, nws feem ntau yog xaiv rau cov ntawv thov uas conductivity yog qhov thib ob rau kev sib koom ua ke.
Weldability thiab Brazability
TP2 zoo tshaj hauv weldability thiab brazability. Cov ntsiab lus phosphorus siab dua ua tus neeg sawv cev fluxing thaum lub sij hawm brazing, txhawb nqa capillary zoo dua thiab cov pob qij txha muaj zog. Qhov no ua rau TP2 qhov kev xaiv zoo tshaj plaws rau cov kav dej, HVAC piping, thiab cov roj siv kho mob uas muaj pa tawm - cov pob qij txha dawb yog qhov tseem ceeb.
TP1 kuj muaj qhov zoo weldability tab sis tej zaum yuav xav tau kev ceev faj ntau dua thaum lub sij hawm brazing. Nws feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau vuam tab sis tsis yog qhov tseem ceeb.
Corrosion Resistance
Ob lub alloys pom zoo heev corrosion kuj nyob rau hauv feem ntau ib puag ncig, xws li dej, atmospheric raug, thiab cov tshuaj me me. Lawv cov ntsiab lus tsis tshua muaj oxygen tiv thaiv "hydrogen embrittlement" hauv kev txo cov huab cua, ua rau lawv ruaj khov nyob rau hauv ntau yam kev pabcuam.
Mechanical Properties
Tensile Strength: TP1 thiab TP2 muaj qhov sib piv tensile lub zog (≈ 215-345 MPa, nyob ntawm qhov kub thiab txias).
Formability: Ob leeg alloys pom zoo ductility thiab txias - ua hauj lwm zog, tshwj xeeb tshaj yog nyob rau hauv lub annealed temper. TP1 cov ntsiab lus phosphorus qis me ntsis tuaj yeem muab qhov txias txias zoo dua -bending kev ua tau zoo.
