Aluminium Copper is also used in the Cast Aluminium lawnmower chassis, from what my scrapmetal dealer told me.
He also said he "Pays a extra 33% for them (NZ$2/kg vs NZ$1.25/kg @ the time).
He sells it directly back to the
foundry that casts the Aluminium lawnmower chassis, so he was a little particular about how clean the castings were.
Also, we used to sell or machine shop turnings to a scrap buyer, since we knew what we were machining we did separate the different Bronzes (Bronze, Phosphor Bronze, Ali Bronze, Gun metal)
Its very **** important NOT to let Aluminium Bronze mix into any other Bronze. They stressed this every time they bought off us.
Its a 'one way' thing, once any Bronze is contaminated with Ali Bronze, that's all its good for, Ali Bronze.
