Kana Al, Nb, V, Ti uye mamwe alloy elements ane nitrogen fixation akawedzerwa kune simbi, iyo nitrogen content haina kukwana. Iyo nitrogen inogadzirisa zvemukati inofanirwa kutsanangurwa mune yemhando chitupa.e. Paunenge uchishandisa aruminiyamu yakazara, iyo yakazara aruminiyamu yemukati Alt ≥ 0020%.
