Raws li lub npe ntawm cov hlau tseem ceeb nrog cov ntsiab lus loj hauv cov hlau, nws raug cais raws li qee yam alloy. Piv txwv li, tooj liab alloy nrog cov ntsiab lus tooj liab siab muaj cov khoom ntawm tooj liab.
Alloy hom
(1) Mixed alloy (eutectic sib tov): thaum cov kua alloy solidifies, lub Cheebtsam constituting lub alloy crystallize nyias, xws li solder, bismuth cadmium alloy, thiab lwm yam;
(2) Cov khoom siv yaj yaj, cov hlau uas tsim cov khoom siv thaum cov kua alloy solidifies, xws li kub thiab nyiaj alloy;
(3) Ib qho hlau uas muaj cov khoom sib txuas ua ke, xws li tooj liab thiab zinc (- Brass - Brass thiab ε- Brass), thiab lwm yam.
Alloy yog superior rau cov hlau ntshiab hauv ntau lub zog, yog li nws feem ntau yog siv rau hauv cov ntaub ntawv thov (saib ferroalloy thiab stainless hlau).
