| The
copper rich end of the copper-aluminum binary phase diagram is shown. The
vertical red line shows the composition: Cu-7 wt % Al. This alloy has the
single phase a-structure,
that is a substitutional solid solution of aluminum in the fcc copper matrix.
This composition has a melting temperature of about 1030 C. This material
is known as an aluminum-bronze.
The material has a UTS of about 500 MPa, a yield stress of 240 MPa, and a % elongation to fracture of about 20 %. |
