Bar Product Terminology and Finish Rolled Alloys, Inc.
AMS 2261 contains dimensional tolerances for aerospace nickel alloy bar products. The terms cold finished, cold worked and cold drawn have different meanings. Cold finished products have tighter dimensional tolerances than those applied to hot finished products. Cold finishing could be any one of many different processing ...

14/01/2019 0183 32It is considered to be one of the most highly joinable alloys. 6262 6262 is a screw machine stock that, when in T6511 temper, offers more strength and machinability than 6061. Cold finished 6262 conforms to AMS QQA225/10 and ASTM B211, and extruded to AMS AAA200/10 and ASTM B211. 7075 Looking for the greatest strength available in aluminum bar
Recommended machining parameters for copper and copper alloys
0183 32of copper and copper alloys Machining copper alloys is considerably easier than machining steels or aluminium alloys of the same strength see Figure 1 . This is reflected in the significantly lower cutting forces as shown in Figure 2. Unless specific technical requirements dictate the use of another material, freecutting brass CuZn39Pb3

Figure 8 shows a hub assembly, manufactured from 7075 aluminum bar. The customer requires that the parts be heat treated to the T73 temper and requires residual stress levels be kept to about 6000 psi or below. To facilitate the machining operation, the material is procured in the T7351 stretcher stress relieved bar and rough machined.
