Stribed Pres
Cyflwyniad Cynnyrch
Dalen Bres yn seiliedig ar gopr electrolytig, sinc ac elfennau hybrin fel ei deunydd crai, trwy brosesu gan ingot, rholio poeth, rholio oer, trin gwres, glanhau arwynebau, torri, gorffen, ac yna pacio. Perfformiad prosesau deunydd, plastigedd, priodweddau mecanyddol, ymwrthedd i gyrydiad, perfformiad a thun da. Fe'i defnyddiwyd yn helaeth mewn diwydiannau trydanol, modurol, cyfathrebu, caledwedd, addurno a diwydiannau eraill.
