Karatasi ya Shaba
Utangulizi wa Bidhaa
Karatasi ya Shaba imeundwa kwa shaba ya electrolytic, kwa njia ya usindikaji na ingot, rolling ya moto, rolling baridi, matibabu ya joto, kusafisha uso, kukata, kumaliza, na kisha kufunga. Nyenzo hiyo ina conduction bora ya mafuta na umeme, ductility rahisi na upinzani mzuri wa kutu. Imekuwa ikitumika sana katika umeme, magari, mawasiliano, vifaa, mapambo na tasnia zingine.
