The copper-aluminium alloys, known as aluminium bronzes, form an important group of engineering materials, characterised by their high strength and corrosion resistance. A solid solution containing up to 9.4+wt% Al with a narrow freezing range similar to the brasses forming a peritectic at 1037°C and 8.5wt% Al. Alloys containing less than 8% aluminium are single-phase a alloys. Solidification commences with the formation of a dendrites. The freezing range is short with the as-cast structure...Read Full Story
