Ni. 3000 1600 noble and Base metals. Classification. Metallurgy divides the metals into two groups known as the noble and the base, so classified because of their affinity for and property of com- bining with oxygen. The former, having less affinity, do not so readily combine with it by absorption from the atmosphere, and are more easily separated from its combination when subjected to heat; while the latter, having a greater affinity, and absorbing it more readily, are separated with much more difficulty because their compounds are not decomposed by heat alone.
