Most metal equipment, e.g. connectors; descending devices; ascending devices, is made 2.10.3.1 of steel or of aluminium alloys, although other metals, such as titanium, are sometimes used. Aluminium alloys and most steels, with the exception of stainless steel, all look the same. However, the performance of these metals can vary greatly, particularly in terms of their corrosion resistance. It is essential, therefore, that the user knows from what the equipment is made, so that relevant precautions can be taken.2.10.3.2 Equipment made from aluminium alloys sometimes has a polished surface finish, but usually it is anodized. Anodizing provides a thin electrochemical coating, which is harder than the base material. This coating protects the base metal against corrosion and also, to a small extent, against wear.The various aluminium alloys used
