Aluminum alloys have the benefit of being one of the lightest ones around. With a density lower than most traditionally used steel alloys, aluminum alloys are coveted for their low weight and moderate tensile strength properties. Because these alloys have very high ductility and are very soft, many Aluminium Flanges Manufacturers in India typically use different tempers on them. Tempering the material increases the tensile strength and improves the impact hardness, making it possible to use for applications that require high strength. Specifications like the ASTM B247 cover various tempers. And so the most common tempers mentioned in the  ASTM B247 for the Aluminium Flanges include  - T4, T6, T61, T7352, T7452, T73, T74, T7454, T852, T652, H112, and H111. Specifications usually cover essential points which act as a sort of guidelines, which help the manufacturer in producing accurate, standardized products like 3003-h112 And 6061-t6 Weld Neck Flange. This specification makes note of tests that are to be conducted on the components. It is typical for any component produced under ASTM specifications such as the ASTM B247 UNS A93003 Slip On Flange to undergo tests like chemical analysis, tension test, hardness test, and mechanical tests (yield and tensile strength, elongation & Brinell hardness). These tests determine the quality of the component produced, while also noting the conformance of the material’s chemical composition. The most common grades of Aluminum Pipe Flanges used in the market include 6082,6061, 5083, and 3003. Out of all these alloys, the most widely used component is the Aluminum 6061 Plate Flange because it offers good weldability and decent mechanical properties suited for general purpose applications.
