Aluminum Alloys 7075 and 6061: Differences and Practical Applications

What are the main differences among aluminium alloys 7075 and 6061 and wherein are they quality wholesale of Aluminum Alloy Wheel Scrap used for? While those are each notably used within the manufacture of bicycle frames and additives, there’s a global of difference between the charter and alertness of the 2.

Where Lies the Difference?

The number one difference among aluminium alloys 6061 and 7075 starts offevolved with their fundamental composition. Aluminium 6061 uses magnesium and silicon as its foremost alloying detail at the same time as aluminium 7075 makes use of zinc. In preferred, aluminium grade 6061 is quite weldable the use of tungsten inert gas (TIG) or metal inert gas (MIG), enormously proof against corrosion and reveals accurate mechanical residences. Alloy 7075, however, famous better tensile power however is notably much less immune to corrosion.

The mechanical houses of both alloys in large part depend on the mood or heat treatment of the cloth. Annealed or pre-tempered grade 6061-O affords the least tensile energy (18,000 psi) and yield power (8,000 psi) while tempered grade 6061-T6 presents the maximum tensile (forty two,000 psi) and yield energy (35,000 psi) a number of the 6061 alloys.

For the 7075 alloys, the un-heat dealt with 7075-O comes on the lower cease of the tensile and yield electricity spectrum (40,000 psi and 21,000 psi, respectively) at the same time as 7075-T6 offers the maximum tensile (74,000 to 78,000 psi) and yield power (63,000 to sixty nine,000 psi).

Practical Applications

Since alloy 7075 is considerably more highly-priced as compared to other aluminium alloys, it’s miles simplest used when inexpensive alloys could now not be enough to do the process. It is most typically used in applications that require high electricity-to-density ratio. As such, 7075 is the alloy of desire whilst it comes to move (automotive, aviation and marine) programs.

Due to its light-weight nature, 7075 is also used within the production of cling glider airframes, mountaineering device, lacrosse stick shafts and bicycle components. Alloy 7075 is likewise used within the manufacture of M16 and precision rifles for the American Army, the Desert Tactical Arms and the French armament employer.

Alloy 6061, then again, is considered to be the aluminium alloy of preference for fashionable purpose use. The alloy’s enormously resistant nature makes it appropriate for the production of heavy-duty structures which includes truck and marine components, tank fittings, scuba tanks and other high strain applications. It can likewise be used inside the manufacture of homebuilt aircraft, small utility yacht and boats, bicycle additives, fly fishing reels and aluminium cans for food packaging. In addition, 6065 is also the most appropriate alloy for decent forging.
