Tin Bronze vs Aluminium Bronze

Tin bronze thiab aluminium bronze yog ob tsev neeg sib txawv ntawm tooj liab -raws li alloys, sib txawv los ntawm lawv cov thawj alloying ntsiab (tin vs. aluminium), uas ua rau muaj kev hloov pauv tseem ceeb hauv tshuaj muaj pes tsawg leeg, txhua yam khoom, corrosion resistance, thiab daim ntawv thov scenarios.

Sib piv Dimension	Tin Bronze (Cu-Sn Alloy)	Aluminium Bronze (Cu-Alloy)
1. Tshuaj muaj pes tsawg leeg	- Lub ntsiab alloying tseem ceeb: Tin (Sn, 3-15% typical; xws li C51000=5% Sn, C52100=8% Sn) - Cov ntsiab lus thib ob: Phosphorus (P, 0.01-0.3% rau deoxidation thiab hnav tsis kam), zinc (Zn, Tsawg dua lossis sib npaug li 5% rau kev txhim kho castability) - Copper (Cu) cov ntsiab lus: 80-97% - Cov qib tseem ceeb: C51000 (Phosphor Bronze), C52100 (8% Sn Bronze), C54400 (Naval Bronze)	- Cov ntsiab lus tseem ceeb ntawm alloying: Aluminium (Al, 6-12% raug; xws li C60600=10% Al, C63000=9% Al) - Cov khoom thib ob: Nickel (Ni, 2-5%), hlau (Fe, 1-4%) rau lub zog thiab corrosion kuj; manganese (Mn) rau toughness - Copper (Cu) cov ntsiab lus: 78-90% - Cov qib tseem ceeb: C60600 (10% Al Bronze), C63000 (Nickel-Aluminium Bronze), C61300 (7% Al Bronze)

3. Corrosion Resistance	- Kev tiv thaiv zoo rau atmospheric corrosion, dej tshiab, thiab tshuaj me me - Kev tiv thaiv tsis zoo rau cov dej hiav txwv (nws yooj yim rau pitting thiab dezincification hauv chloride ib puag ncig) - Phosphorus ntxiv (C51000) txhim kho kev tiv thaiv hnav thiab khaus	- Kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav: dej hiav txwv, tshuaj tsuag ntsev, kua qaub (tsis suav nrog muaj zog oxidizing acids zoo li nitric acid), thiab cov tshuaj muaj - Forms a dense aluminum oxide (Al₂O₃) passive film on the surface, preventing further oxidation - Zoo tshaj rau tin bronze hauv marine thiab offshore daim ntaub ntawv
4. Kev ua haujlwm zoo	- Castability: Zoo (tsim rau xuab zeb casting, centrifugal casting) - Machinability: Nruab nrab (phosphor bronze yooj yim dua rau tshuab dua qib siab - tin qib) - Formability: Zoo heev (cov qib annealed tuaj yeem raug stamped, sib sib zog nqus- kos, lossis kos rau hauv cov xov hlau / lub caij nplooj ntoo hlav) - Weldability: Tsis zoo (yuav ua rau kub tawg; yuav tsum tau preheating thiab tshwj xeeb muab tub lim)	- Castability: Ncaj (ntau dua melting point tshaj tin bronze; yuav tsum tau tswj kom txias kom tsis txhob porosity) - Machinability: Tsis zoo (siab hardness thiab toughness; xav tau cov cuab yeej carbide thiab qeeb txiav ceev) - Formability: Nruab nrab (cov qib annealed tuaj yeem khoov lossis stamped, tab sis txwv tsis pub muaj qhov sib sib zog nqus nqus) - Weldability: Zoo dua li tin bronze (tuaj yeem welded ntawm GTAW/MIG nrog cov khoom sib txuam; post-weld kev kho cua sov pom zoo)
5. Thermal/Electrical conductivity	- Hluav taws xob conductivity: 20-30% IACS (International Annealed Copper Standard) - Thermal conductivity: 50-70 W / (m·K) - Haum rau qis- daim ntawv thov hluav taws xob tam sim no (piv txwv li, springs, hu)	- Hluav taws xob conductivity: 8-15% IACS - Thermal conductivity: 30-50 W / (m·K) - Tsis pom zoo rau daim ntawv thov hluav taws xob; muab qhov tseem ceeb rau kev siv tshuab / siv tshuab
6. Daim ntawv thov Scenarios	- Muaj: Precision springs, hluav taws xob tiv tauj, ntxhua khaub ncaws, cov khoom siv suab paj nruag, iav (tsawg-load) - Tubrog nkoj: Cov dej tsis qab, cov khoom siv, thiab cov fasteners (tsis yog rau dej hiav txwv immersion) - Cov khoom siv: Cov khoom siv kho kom zoo nkauj, cov hniav nyiaj hniav kub, thiab cov khoom me me	- Muaj: Hnyav- lub cev muaj zog, bearings, twj impellers, li qub, thiab hnav daim hlau (siab-load, siab- ib puag ncig hnav) - Marine: Seawater li qub, kiv cua, hull fittings, thiab offshore platform Cheebtsam - Aerospace/Defense: Kev tsaws iav cov khoom, hydraulic fittings, thiab corrosion-cov khoom siv tiv thaiv
7. Tus nqi	- Tus nqi qis (tin yog pheej yig dua li aluminium-nickel- hlau ua ke) - Tus nqi- zoo rau nruab nrab- thauj khoom, tsis yog- corrosive ib puag ncig daim ntawv thov	- Tus nqi siab dua (txhuas + npib tsib xee / hlau ntxiv nce cov khoom siv raw thiab cov nqi ua haujlwm) - Tsim nyog rau siab -lub zog, corrosion- cov kev cai tiv thaiv (tag nrho cov nqi ntawm cov tswv cuab qis dua nyob rau hauv ib puag ncig hnyav)

Alloying Element cuam tshuam: Tin bronze prioritizes qaug zog thiab ductility, thaum txhuas bronze tsom rau siab zog, hnav tsis kam, thiab corrosion kuj (tshwj xeeb tshaj yog seawater).

Daim ntawv thov Matching:

Pom zoo tin bronze (C51000, C52100) rau cov neeg siv khoom xav tau stamping / hlau kos qhov chaw, qis -load springs, los yog cov ntawv thov dej tshiab.

Pom zoo aluminium bronze (C60600, C63000) rau marine, offshore, los yog siab- hnav cov haujlwm ua lag luam (tseem ceeb txog nws cov nqi-kev pab cuam nyob rau hauv ib puag ncig hnyav).

Rau kev siv dej hiav txwv, qhia meej meej txog txhuas bronze (C63000 yog qhov zoo dua rau qhov tsis zoo corrosion).

Rau precision Cheebtsam xav tau ductility, highlight tin bronze lub superior formability thiab qaug zog kev ua tau zoo.

Qhia meej txog kev ua tiav (piv txwv li, vuam, machining) raws li txhuas bronze yuav tsum tau tshwj xeeb kev tsim khoom.

Qhov kev sib piv no siv cov ntsiab lus tsim qauv thiab qib kev xaiv (ASTM / ISO) los txhawb kev sib txuas lus, kev hais lus, thiab kev txiav txim kom pom zoo hauv cov khoom siv hlau txawv teb chaws.
