1. Ntshiab aluminium
(1) impurity ntsiab: Tag nrho cov impurity ntsiab yuav txo cov conductivity ntawm txhuas
(2) Hlau thiab silicon: Yog hlau thiab silicon coexist nyob rau hauv txhuas, cov yas thiab corrosion kuj ntawm txhuas yuav raug txo.
(3) Copper: tooj liab txo qhov corrosion kuj ntawm txhuas
(4) Zinc: Zinc kuj txo cov corrosion kuj ntawm txhuas
2. Deformed aluminium alloys
(1) Tooj thiab magnesium: tooj liab tuaj yeem txhim kho lub zog thiab hardness ntawm txhuas alloys. Ntxiv nrog rau kev txhim kho lub zog thiab hardness, magnesium feem ntau txhim kho corrosion kuj ntawm aluminium alloys. Tooj liab thiab magnesium ua hauj lwm ua ke kom ntxiv dag zog rau txhuas alloys los ntawm quenching thiab aging.
(2) Zinc: Zinc tuaj yeem txhim kho kev laus ntxiv dag zog ntawm aluminium alloys thiab txhim kho machinability thiab thermoplasticity, tab sis nws txo qis qaug zog thiab intergranular corrosion kuj.
(3) Manganese: Manganese tuaj yeem txhim kho lub zog ntawm aluminium alloys.
(4) Titanium thiab boron: titanium thiab boron tuaj yeem kho qhov loj ntawm cov hlau thiab txhim kho nws lub zog.
(5) Silicon: Silicon tuaj yeem txhim kho cov thermoplasticity ntawm aluminium alloys thiab txhim kho lawv cov kev kho cua sov ntxiv zog.
(6) Hlau thiab npib tsib xee: Hlau thiab npib tsib xee tuaj yeem txhim kho lub zog ntawm wrought aluminium tom qab quenching thiab aging.
3. Casting aluminium alloys
(1) Silicon - Silicon tuaj yeem txhim kho fluidity, lub zog thiab corrosion kuj ntawm cam khwb cia txhuas alloys, txo shrinkage thiab tawg.
(2) Tooj thiab magnesium - tooj liab thiab magnesium tuaj yeem txhim kho lub zog thiab hardness ntawm aluminium alloys los ntawm quenching thiab aging. Tooj liab kuj tuaj yeem txhim kho nws cov dej ntws zoo, thaum magnesium muaj qhov cuam tshuam tsis zoo, tab sis nws tuaj yeem txhim kho nws cov corrosion kuj
(3) Zinc - Zinc tuaj yeem txhim kho cov castability thiab lub zog ntawm cam khwb cia txhuas alloys, tab sis txo nws cov corrosion kuj.
(4) Nickel - Nickel tuaj yeem txhim kho lub zog thermal ntawm cam khwb cia txhuas alloys
