Copper hlau muaj hluav taws xob zoo thiab thermal conductivity, corrosion kuj thiab machining zog, tuaj yeem welded thiab brazed.Muaj qhov txo qis hluav taws xob thiab thermal conductivity impurities tsawg dua, cov pa oxygen tsis tshua muaj kev cuam tshuam rau hluav taws xob thiab thermal conductivity thiab kev ua haujlwm, tab sis yooj yim ua "hydrogen kab mob", yuav tsum tsis txhob kub siab (xws li> 370 ℃) hauv kev txo cov huab cua ua haujlwm ( annealing, vuam, thiab lwm yam) thiab siv.
