Manufacturing lock nuts with aluminum 7075 T6 results in the perfect lock nut for highly stressed applications. The high strength of Aluminum 7075 T6 makes a perfect pairing with the torque and vibration resistance of lock nuts.

Aluminum 7075 T6 is an aluminum-zinc alloy with 1 to 8 percent zinc. Small amounts of magnesium are also added to Aluminum 7075 as are copper and chromium. To achieve the T6 temper, Aluminum 7075 is solution heat-treated and artificially aged until it meets standard mechanical property requirements.

Aluminum 7075 T6 is comparable to Aluminum 2024 but is best used when higher mechanical properties are desired. Additionally, aluminum 7075 T6 lock nuts offer a low density.
