  • Used for?

    Was given a piece of aluminum Bronze, 1 1/2 in diameter. What is this metal usually used for? Thanks.

    One application is bearings in the retract mechanism of some light planes.

      It is used in training, to let you get the feel of machining it

      I may still have a piece of that. I hope I don't find it one day and forget the fun I had trying to make something out of it
      I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

        Yes I have a piece (1/2"x3"x36") also that I'm saving for the ideal application but so far it's still gathering dust. So far any projects for it's use have not shown up due to my projects needing a length of 1 1/2" round bar instead of the flat bar I already have.
        Just kidding!

        A link below of some other uses for this alloy as well as it's properties.

          Depending on grade, CA104 aluminium bronze I have been told is a great material for skulling a cylinder head (machining out a pocket to take a insert in place of the combustion chamber, and machining a combustion chamber shape with new profiles etc into the insert).
          I believe with the CA104 skull, the requirement for valve seats goes away too, however when I priced up enough to do my current engine, it came to a shade over $800 at the suppliers for a suitable length of barstock so its on hold as a project.

            I used some in the last couple of months to make bushings for a small tower clock.

              The flat pieces are often used to make sliding wear surfaces.

                how long is it? if 10" or more use it to check how true your lathe turns. (chuck it up, turn it down and measure the taper.)

                  It us used to test your skills as a machinist. It machines about like M4 tool steel. If you decide to machine it run things slow and keep it feeding.

                    Right on, Brian! I might add, if you try to tap it smaller than 1/4" it might not work (breaks tap). If you tap larger sizes, use a top-quality, sharp tap (I have the best luck with spiral-point taps) and keep your fingers crossed.
                    On the bright side, it does leave a gorgeous finish when turning.

                      If you need to tap it you might want to use a slightly larger tap drill than usual.

                        Thanks everyone the piece isn't real long, i will just chuck it up, and do a few test passes first, i was thinking bushings of some sort.

                          Sasquatch: I have seen it used to make hammer heads. It makes a non-sparking hammer head to be used in places such as refineries or paint lines where explosions are a danger.

                            You'll have fun drilling it.
                            AL-BNZ likes to "Squeeze" drills.
                            Peck drill, ALOT! And use oil or coolant.
                            We ran a lot of AL-BNZ for oilfield valve seats, and marine parts.
