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.
Summary. 1  Aluminised steel is a bit economical than the stainless steel. 2  The stainless steel is stronger of the two. They are also more durable than aluminised steel. 3  In respect to rusting, stainless steel does not rust. Aluminised steel can get corroded if the aluminium coat gets broken.
