Gníomhachtaithe alúmana le neart ard, abrasion íseal, gan aon laghdaíonn in uisce, gan aon leathnú, gan powdery agus aon crack. Is féidir é a úsáid go forleathan i thriomú ndoimhneacht na gáis scáinte, eitiléin agus próipiléin, hidrigine glúin, scaradh aer, a thriomú aeir ionstraim agus cóireáil fluairín do H2O2, chomh maith i an t-ábhar ar thruailliú ionsú, cosúil le H2S, SO2, HF agus pairifín sa gás dramhaíola, go háirithe san defluorinate uisce óil.
