Folja tar-ram
Introduzzjoni tal-Prodott
Folja tar-ram ibbażata fuq ir-ram elettrolitiku, iż-żingu u l-elementi tat-traċċa bħala l-materja prima tiegħu, permezz tal-ipproċessar permezz ta 'ingot, rolling sħun, rolling kiesaħ, trattament tas-sħana, tindif tal-wiċċ, qtugħ, irfinar, u mbagħad ippakkjar. Proċessi tal-materjal il-prestazzjoni, il-plastiċità, il-proprjetajiet mekkaniċi, ir-reżistenza għall-korrużjoni, il-prestazzjoni u l-landa tajba. Intuża ħafna fl-elettriku, karozzi, komunikazzjonijiet, ħardwer, dekorazzjoni u industriji oħra
