<p>A nitrogenous Al-Si powder metallurgical alloy contains at least 4wt% and at most 15wt% of nitrogen, a least 8.5wt% and at most 48wt% of silicon, at most 9.6wt% of at least one element selected from the group consisting of Li, Mg, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo and W, with the remaining part consisting essentially of Al. Consequently, a highly safe material which is light and having the density of at most 3.0g/cm<3>, thermal expansion coefficient of from 5 to 10x10<-><6>/ DEG C and thermal conductivity coefficient of at least 0.2cal/cm.sec. DEG C can be obtained. <IMAGE></p> |
