Karatasi ya Shaba
Utangulizi wa Bidhaa
Karatasi ya Shaba imetengenezwa kwa shaba ya kielektroliti, kupitia usindikaji kwa ingot, kuzungusha kwa moto, kuzungusha kwa baridi, matibabu ya joto, kusafisha uso, kukata, kumalizia, na kisha kufungasha. Nyenzo hii ina upitishaji bora wa joto na umeme, unyumbufu unaonyumbulika na upinzani mzuri wa kutu. Imetumika sana katika tasnia za umeme, magari, mawasiliano, vifaa, mapambo na viwanda vingine.
