FIELD: chemistry.
SUBSTANCE: aluminium-copper alloy for casting, containing in fact insoluble particles, which occupy inter-dendritic regions of the alloy, and free titanium in an amount, sufficient for crushing the granular structure in the casting alloy. The alloy contains, wt %: Cu 3.0-6.0 , Mg 0.0-1.5, Ag 0.0-1.5, Mn 0.0-0.8, Fe 0.0-1.5, Si 0.0-1.5, Zn 0.0-4.0, Sb 0.0-0.5, Zr 0.0-0.5, Co 0.0-0.5, free titanium >0.15-1.0, insoluble particles 0.5-20, Al and inevitable admixtures - the remaining part. The insoluble particles occupy the inter-dendritic regions of the alloy and contain particles of titanium diboride.
EFFECT: aluminium-copper alloy possesses high plasticity and tensile strength, as well as fatigue life.
