The clavicular insertion of this muscle varies in extent; it sometimes reaches as far as the middle of the clavicle, and occasionally may blend with the posterior edge of the Sternocleidomastoideus, or overlap it.
In typical commercial aluminium anodizing processes, the aluminium oxide is grown down into the surface and out from the surface by equal amounts. So anodizing will increase the part dimensions on each surface by half the oxide thickness.
Optimum rare earth levels in a nodularizer are a function of the purity of the raw. materials used and of casting m ethodology. Calcium moderates the reaction between the Magnesium and the base iron, reducing its. violence. However, excessive calcium in the alloy may produce slag. The presence of. aluminum can under certain conditions promote pinhole formations in Ductile Iron and must be. controlled .
