Cyflwyniad Cynnyrch
Mae stribed efydd yn gopr gyda thun, alwminiwm, ac elfennau hybrin fel deunyddiau crai, trwy brosesu gan ingotau, rholio poeth, rholio oer, triniaeth wres, glanhau wyneb, torri, gorffen a phacio, deunyddiau â chryfder cynnyrch uchel, cryfder blinder, eiddo elastig a formability plygu rhagorol.Fe'i defnyddiwyd yn helaeth mewn soced CPU cyfrifiadurol, terfynellau ceir, bysellbad ffôn symudol, cysylltwyr electroneg trydanol ac uwch-dechnoleg eraill.
