Core Advantages ntawm Silicon hlau 441 rau Aluminium Alloys
Unmatched Impurity Balance: Qhov "Sweet Spot"
Aluminium alloys yog qhov nkag siab zoo rau Fe, Al, thiab Ca impurities -txawm tias qhov hloov pauv me me tuaj yeem ua rau castability thiab mechanical kev ua tau zoo. Si441 cov kev txwv yog engineered rau txhuas:
Tsawg Ca ( Tsawg dua lossis sib npaug li 0.1%): Calcium tshuaj lom Sr / Na modifiers siv rau eutectic refinement hauv Al-Si alloys. Silicon hlau 441's Ca yog 1/3 ntawm 553 (0.3%), tshem tawm kev hloov pauv tsis ua haujlwm, shrinkage porosity, thiab txo ductility.
Tswj Fe (tsawg dua los yog sib npaug li 0.4%): Hlau cov ntaub ntawv nyuaj Al₅FeSi intermetallic. Si441's qis Fe txo qhov brittleness, txhim kho elongation nyob rau hauv nyias-wall castings, thiab txo cov machining "nyuaj chaw".
Balanced Al (tsawg dua lossis sib npaug li 0.4%): Residual Al ua raws li cov hmoov nplej me me uas tsis muaj ntau tshaj AlN suav nrog, ua kom ntseeg tau tias muaj kev tswj xyuas cov tshuaj tiv thaiv rau cov neeg tsim khoom.
Superior Castability & txo qhov tsis xws luag
Silicon yog cov khoom siv zoo tshaj plaws los txhawb cov txhuas fluidity, txo cov kua muag kub, thiab txo qis qis. Si441 lub siab purity thiab tsawg impurities ua kom cov txiaj ntsig zoo no:
Ntau dua yaj fluidity: Txhim kho pwm filling rau complex, nyias-wall Cheebtsam (xws li, automotive engine blocks, kis vaj tse).
Tsawg dross & porosity: Tight Ca tswj txo cov oxide tsim, txhim kho nto tiav thiab cov yam ntxwv sib xws.
Kev sib koom ua ke: ruaj khov impurity theem tiv thaiv batch-to-batch variation hauv casting zoo.
Txhim kho Mechanical Properties
Si441 ncaj qha txhim kho lub zog, hardness, hnav tsis kam, thiab corrosion kuj ntawm aluminium alloys:
Lub zog tensile siab dua: Txo brittleness los ntawm qis Fe boosts ductility thiab cuam tshuam tsis kam.
Zoo hnav tsis kam: Optimized Si cov ntsiab lus txhim kho hardness, zoo tagnrho rau tsheb thiab cov khoom lag luam.
Ruaj khov thermal expansion: High-Si alloys muaj qis thermal expansion, zoo meej rau precision qhov chaw.
Nqi-Performance Leadership
Thaum Si441 yog pricier dua silicon hlau 553, nws muab cov nqi tsim khoom qis dua:
Txo cov khoom seem: Tsawg qhov tsis xws luag (porosity, tawg) txiav cov khoom pov tseg.
Kev siv tsawg dua kev hloov pauv: Tsawg Ca tshem tawm cov tshuaj lom neeg hloov pauv, txuag ntawm cov khoom siv kim Sr / Na.
Tsis muaj nqi them tshaj rau kev ua kom huv: Pheej tshaj 1101 (99.7% Si) thaum ua tau zoo tshaj 553/3303.
Si441 vs lwm qib Silicon rau Aluminium Alloys
Vim li cas 441 qib silicon hlau yeej: Nws yog tib qib uas sib txuas ntau dua lossis sib npaug rau 99% purity, qis Ca (Less dua lossis sib npaug li 0.1%), tswj Fe / Al, thiab tus nqi nruab nrab- kev sib xyaw ua ke tsis muaj lwm qhov sib tw qib.
| Qib | Si (min) | Fe (max) | Al (max) | Ca (max) | Zoo tshaj rau | Cov kev txwv tseem ceeb |
|---|---|---|---|---|---|---|
| Si441 | 99.0% | 0.4% | 0.4% | 0.1% | Premium castings, automotive, 4xxx / 6xxx alloys | Me ntsis tus nqi siab dua 553 |
| Si 553 | 98.5% | 0.5% | 0.5% | 0.3% | Cov khoom tsim tawm dav dav | High Ca tshuaj lom modifiers; siab dua seem |
| ib 3303 | 99.3% | 0.3% | 0.3% | 0.3% | High-purity alloys | Siab Ca; kim tshaj 441 |
| Sib 1101 | 99.7% | 0.1% | 0.1% | 0.01% | Aerospace, ultra-precision qhov chaw | Tus nqi qis heev rau kev siv lub hauv paus |
Si441 tsis yog lwm qib silicon xwb - nws yog qhov kev daws teeb meem zoo rau kev tsim cov txhuas alloy. Nws qhov sib npaug impurity profile (0.4% Fe, 0.4% Al, 0.1% Ca), siab purity (Ntau dua lossis sib npaug rau 99% Si), superior castability, txhim kho cov khoom siv kho tshuab, thiab cov nqi ua haujlwm zoo ua rau nws zoo dua 553, 3303, thiab 1101 rau feem ntau cov ntawv siv txhuas.
Rau cov chaw tsim khoom thiab cov neeg tsim khoom tsim los txhawm rau txhim kho qhov zoo, txo qhov tsis xws luag, thiab tswj cov nqi, Si441 yog qhov kev xaiv zoo tshaj plaws - tus qauv kev lag luam uas sib npaug kev ua haujlwm thiab tus nqi.
