Folja tar-ram
Introduzzjoni tal-Prodott
Folja tar-ram ibbażata fuq ram elettrolitiku, żingu u oligoelementi bħala materja prima tagħha, permezz ta 'proċessar permezz ta' ingott, rolling bis-sħana, rolling kiesaħ, trattament bis-sħana, tindif tal-wiċċ, qtugħ, irfinar, u mbagħad ippakkjar. Il-materjal jipproċessa l-prestazzjoni, il-plastiċità, il-proprjetajiet mekkaniċi, ir-reżistenza għall-korrużjoni, il-prestazzjoni u l-landa tajba. Ġie użat ħafna fl-elettriku, tal-karozzi, komunikazzjonijiet, ħardwer, dekorazzjoni u industriji oħra
