in structure has not only varied morphologies but also different genesis of its origin,
which associated with Zn appearance in ternary Cu-Al-Fe system.
According to mechanical properties investigation, it has been recommended to
use in industrial practice bronze BrA9Zh3L doping with zinc in amount not exceeded
0,2 wt. % Zn against normatively permitted concentration 1,0 wt. % Zn.
Industrial testing of present work results have been shown that implementation of
bronze BrA9Zh3L effective structural formation new technological solutions allows in
industrial practice the yield of conformed castings increasing, the failure of casting by
cracks in 2 ... 8 times reducing and the stable high level of mechanical properties
providing, that will improve reliability and durability of products.
