Aluminium Bronze AB2 Bar Manufacturer, Suppliers, Exporter, Wholesaler and Distributor in Mumbai, India
Aluminium bronze AB2 is a high strength copper based alloy with aluminium being the primary alloying element (typically 5 – 11% aluminium). It is also the most tarnish resistant of all the copper alloys i.e the appearance of the material does not deteriorate when exposed to the effects of atmospheric corrosion. Aluminum Bronze AB2 is a family of copper-based alloys offering a combination of mechanical and chemical properties unmatched by any other alloy series. This feature makes the Aluminum Bronze the first choice for demanding applications. Aluminium bronze Ab2 are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. They are also resistant to corrosion in seawater.
Aluminium bronze resistance to corrosion results from the aluminium in the alloy, which reacts with atmospheric oxygen to form a thin, tough surface layer of alumina (aluminium oxide) which acts as a barrier to corrosion in the copper rich alloy. The addition of tin as well can improve corrosion resistance.
