Ukanda wa shaba
Utangulizi wa bidhaa
Karatasi ya Brass kulingana na shaba ya elektroni, zinki na vitu vya kufuatilia kama malighafi yake, kupitia usindikaji na ingot, kusongesha moto, kusongesha baridi, matibabu ya joto, kusafisha uso, kukata, kumaliza, na kisha kupakia. Utendaji wa michakato ya nyenzo, plastiki, mali ya mitambo, upinzani wa kutu, utendaji na bati nzuri. Imetumika sana katika umeme, magari, mawasiliano, vifaa, mapambo na viwanda vingine
