Strixxa tar-ram
Introduzzjoni tal-Prodott
Folja tar-ram ibbażata fuq ram elettrolitiku, żingu u elementi traċċa bħala l-materja prima tagħha, permezz ta' pproċessar permezz ta' ingott, irrumblar bis-sħana, irrumblar fil-kesħa, trattament bis-sħana, tindif tal-wiċċ, qtugħ, irfinar, u mbagħad ippakkjar. Il-prestazzjoni tal-proċessi tal-materjal, il-plastiċità, il-proprjetajiet mekkaniċi, ir-reżistenza għall-korrużjoni, il-prestazzjoni u l-landa tajba. Intużat ħafna fl-elettriku, tal-karozzi, tal-komunikazzjonijiet, tal-ħardwer, tad-dekorazzjoni u industriji oħra.
