Bronze ke ntho e tloaelehileng ea tšepe bophelong ba rona. Qalong e ne e bua ka alloy ea koporo-tin. Empa indastering, lisebelisoa tsa koporo tse nang le aluminium, silicon, lead, beryllium, manganese le lisebelisoa tse ling tsa tšepe. Lisebelisoa tsa li-tube tse entsoeng ka boronse ba tin, boronse ba aluminium, boronse ba silicon, boronse ba lead. Li-tubes tsa bronze li ka aroloa ka mekhahlelo e 'meli: li-tubes tsa boronse tse entsoeng ka khatello le li-tubes tse entsoeng ka boronse. Lisebelisoa tsena tsa li-tube tsa boronse li ka sebelisoa bakeng sa likarolo tse tlas'a ho hohlana kapa ho bola liindastering tse kang lisebelisoa tsa lik'hemik'hale le likarolo tse sa senyeheng.
