The PB103 alloy is one of a range of Cu: Sn: P alloys continuous cast generally in rod or billet form and also as hollow section. These alloys have excellent casting properties cast in either the horizontal or vertical mode. Thermal anaylses data published by INCRA19. Figure 5.14 indicates the freezing characteristics.
It will be noted that the freezing range between liquidus and the ternary reaction temperature Liq + a?B + Cu3P given as 405°C.
