Likarolo tsa koporo

Tlhaloso e Khutšoanyane:

Brass alloy ke motsoako oa koporo le zinki, ka litekanyo tse ka fapanyetsanoang ho fihlela thepa e fapaneng ea mochini, ea motlakase le ea lik'hemik'hale.Ke motsoako oa substitutional: liathomo tsa likarolo tse peli li ka nkela sebaka se seng ka har'a sebopeho se tšoanang sa kristale.
