Duilleag Brass
Ro-ràdh Bathar
Bileag umha stèidhichte air copar electrolytic, sinc agus eileamaidean lorg mar an stuth amh, tro ghiollachd le ingot, roiligeadh teth, roiligeadh fuar, làimhseachadh teas, glanadh uachdar, gearradh, crìochnachadh, agus an uairsin pacadh. Coileanadh pròiseasan stuthan, plastachd, feartan meacanaigeach, strì an aghaidh creimeadh, coileanadh agus deagh staoin. Tha e air a bhith air a chleachdadh gu bitheanta ann an dealain, càraichean, conaltradh, bathar-cruaidh, sgeadachadh agus gnìomhachasan eile
