WebExamples of parts that are cold extruded are collapsible tubes, aluminum cans, cylinders, gear blanks. The advantages of cold extrusion are: Hot Extrusion: Hot extrusion is done at fairly high temperatures, approximately 50 to 75 % of the melting point of the metal. The pressures can range from 35-700 MPa (5076 - 101,525 psi). WebJan 12, 2015 · Extruded v/s cold finished 6061 aluminum, diameter tolerances for collet work I have to make some parts out of 6061 that will just fit inside of a .750 round aluminum rod, (.720). Extruded is half the price of cold finished, (On-Line Metals), so that would be the obvious choice except I want to feed these out of a .750 5C collet.

WebFeb 6, 2016 · It stands to reason that cold finished will be rather accurate in diameter and the bars round. Extruded could be less accurate and the diameter may not be consistent as well as the bars possibly not being reasonably round. As extruded is a much lower price, I wish to run it, if there are no repeating problems trying to feed or chuck it. WebAL-2024 (UNSA902404) is an aerospace aluminum bar with cold finished or extruded aluminum wrought product providing high to moderate strength, very good machinability and weld ability with improved stress corrosion cracking resistance. 2024 is known as the “aircraft alloy” in machining rod.
