C35000 tooj dag Alloy Composition
C35000 tooj dag yog cov hlau lead uas feem ntau yog tooj liab, zinc, txhuas, thiab hlau. Cov ntsiab lus tooj liab nyob rau hauv no alloy feem ntau yog nyob ib ncig ntawm 65-70%, thaum lub zinc concentration ranges ntawm 27-35%. Cov me me ntawm cov hlau thiab txhuas txhim khu kev ua haujlwm thiab txhim kho lub zog thiab hnav tsis kam. Cov hlau no tseem paub txog nws qhov siab thiab zoo thermal conductivity, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hluav taws xob thiab thermal.
