6060 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is much more closely related to the alloy 6063 than to 6061.The main difference between 6060 and 6063 is that 6063 has a slightly higher magnesium content.

[1] [2] In older systems of terminology, 2XXX series alloys were known as duralumin, and this alloy was named 24ST. 2024 is commonly extruded, and also available in alclad sheet and plate forms. It is not commonly forged (the related 2014 aluminium alloy is, though).
Thrust bearings are also used with radio antenna masts to reduce the load on an antenna rotator. One kind of thrust bearing in an automobile is the clutch "throw out" bearing, sometimes called the clutch release bearing. [4] [clarification needed] [5] [6]
The two halves of the bearing are then split at the shim, the shim removed, the oil holes cleared of metal and oil ways are cut into the surface of the new bearing. The shaft is smeared with engineer's blue and rotated in the bearing. When the bearing is disassembled the blue fills the hollows and is rubbed off the high spots, making them visible.
Unhardened 5086 has a yield strength of 120 MPa (17 ksi) and ultimate tensile strength of 260 MPa (38 ksi) from −28 to 100 °C (−18 to 212 °F). At cryogenic temperatures it is slightly stronger: at −196 °C (−321 °F), yield of 130 MPa (19 ksi) and ultimate tensile strength of 380 MPa (55 ksi); above 100 °C (212 °F) its strength is reduced.

The first, a 665 foot (203 m) half-wave mast was installed at radio station WABC's 50 kW transmitter at Wayne, New Jersey in 1931. [4] [5] During the 1930s it was found that the diamond shape of the Blaw-Knox tower had an unfavorable current distribution which increased the power emitted at high angles, causing multipath fading in the listening ...
