White pīataata mata-pokapū whakarewa hanganga pūtoru, ngohengohe, ductility tuarua anake ki te koura, ko te kaikawe pai o te wera me te hiko;e kore e tauhohe ki te wai me te hāora hau, ka pango ina pa ana ki te ozone, te hauwai sulfide me te whanariki;He ngoikore ki te nuinga o nga waikawa, a ka tere te memeha i roto i te waikawa nitric waimeha me te waikawa pungatara wera.Ka taea e te waikawa pūhaumāota te waikura i te mata me te memeha i roto i te rewa alkali hydroxide, peroxide alkali me te alkali cyanide i te rangi, i te aroaro o te hāora;Ko te nuinga o nga tote hiriwa he tairongo ki te marama, kare e rewa i roto i nga waikawa maha.
