The 6061 T651 aluminum alloy, also known as “duralumin”, is noted for its good mechanical resistance, due to its hardening by mechanical work and heat treatment. It offers regular machinability and weldability characteristics, this alloy is suitable for ionized and galvanic finishing, it is commonly used in the manufacture of fixtures, gages, and lightweight mechanical components. Offering greater corrosion resistance than 7000 series alloys, its versatility makes the alloy a solution for various mechanical applications, including polymer molding and manufacturing of medical equipment components.
The 6061 T651 aluminum alloy, also known as “duralumin”, is an outstanding solution in the manufacturing industry due to its robust mechanical resistance, its supply condition under a precipitation hardening treatment, this alloy has a balanced chemical composition, with percentages of Mg, Cr, Cu, Si, Zn, Fe, Mn and Ti that contribute to its exceptional characteristics.
Supplied in rolled or extruded versions, the 6061 T651 alloy is subjected to heat treatments for aging precipitation hardening, which gives it notable mechanical properties, with a tensile strength of at least 290 N/mm2, a yield strength of at least 241 N/mm2 and a hardness of 95 HBN, this alloy is suitable for various high strength and low weight applications.
In terms of physical properties, the 6061 T651 alloy offers a thermal expansion coefficient of 0 x 100 in the range from 24.0 to 10°C. -6/°C, in addition, in the range of 0 to 200°C it offers thermal conductivity of 1,180 BTU in/ft2 h°F.
Distinctive characteristics of 6061 T651 include fair machinability, acceptable weldability characteristics, and susceptibility to surface finishing processes such as anodizing, chrome plating, and nickel plating. Although it has greater resistance to corrosion compared to the 7000 series, its versatility makes it a choice as a solution for structural components in the manufacture of fixtures, gages, mechanical components, it is used in polymer molding processes such as thermoforming, vulcanizing , polyurethanes, as well as to a lesser extent manufacturing of medical equipment components.
