Annealing Aluminum casting A380
Annealing Aluminum casting A380
(OP)
Hi. I am thinking to replace an extruded aluminum cover with a cast aluminum part (A380). The assembly process requires swaging and I am afraid that the hardness of the casting may lead to fracture and premature tool wear when swaging. I am thinking that annealing would improve ductility. Does someone know where I may find a specific recipe for A380? Is this an "all-or-nothing" process? In other words, can I get a half annealed part?(I would like to retain some strength)
Thanks
Thanks

The first thing you will find out is that, for a lot of 'technical reasons' that will not be revealed, even|especially to a technical person such as yourself, you can't get a casting in any alloy other than A356.
You might be able to have it delivered in -0 temper instead of the usual/ mandatory for 'technical reasons' -T6. You probably won't like how dead soft the -0 temper is.
