Brass Sawb
Khoom Taw Qhia
Brass Sheet raws li electrolytic tooj liab, zinc thiab kab kawm raws li nws cov khoom siv raw, los ntawm kev ua los ntawm ingot, kub dov, txias dov, kev kho cua sov, qhov chaw tu, txiav, tiav, thiab tom qab ntawd ntim. Cov txheej txheem kev ua tau zoo, plasticity, mechanical zog, corrosion kuj, kev ua tau zoo thiab zoo tin. Nws tau dav siv hauv hluav taws xob, tsheb, kev sib txuas lus, kho vajtse, kho kom zoo nkauj thiab lwm yam lag luam
