6. FIG. 409 Muscles connecting the upper extremity to the vertebral column. (See enlarged image). 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.
Save. Aluminum has a high strength-to-weight ratio, and its patina is the same color as the metal. Therefore, many industries use aluminum, in place of steel or plastic, for strong, lightweight parts that resist corrosion. However, the aluminum surface does oxidize, and oxidation weakens the metal.luminum has a high strength-to-weight ratio, and its patina is the same color as the metal.
