The Shel gong mentiones indian (or chinese?) as well as tibetan brass, each having a whitish male (pho rag) and a green-yellow female type (mo rag), determined by the copper-tin proportions. According to dGa' ba'i rdo rje (1995), pho rag consists of copper and tin in equal parts, mo rag contains 1 part of tin and 3 parts of copper. At the end of the notice of zinc, ti tsha, he mentions the 'brass ore', rag rdo, of the Shel gong shel phreng, but qualifies it as a kind of zinc ore.
Bronze, 'khar ba (alloy of copper, zangs, and tin, gsha' dkar), and brass, rag/ra gan, 'khro and li (alloy of copper, zangs, and zinc, ti tsha) have a similar use, and both are called bell-metal.
Aurichalcite (Zn,Cu)5(CO3)2(OH)6, with a variable Zn:Cu ratio), yellow copper or brass, is named after Aurichalcum (Latinized version of the Greek "mountain copper") in allusion to its copper and zinc content, the constituents of brass. A secondary mineral in copper and zinc deposits, aurichalcite is typically found as blue or green crusts or mats of tiny, often feathery, tufted crystals (mindat.org).
The indian name rīti can denote pale brass, iron rust or score of any metal upon exposure to heat and air (widomlib.org)
