From molten metal to 3.2 mm wire for mechanical applications

Abstract

Aluminum utilization is growing at a steady rate reaching 40 million tons per year considering remelt and semis. Among semis, aluminum rod accounts for approximately 10% of the worldwide consumption, mainly for power transmission. Numerous aluminum alloys have been developed and utilized for various mechanical applications and welding purposes. Many rod alloys are difficult to produce and require highly experienced operators and the most advanced machinery and technical know-how. In the form of wire, from molten metal to 3.2 mm wire, the situation becomes even more critical and only the latest Properzi C.C.W. (Continuous Cast Wire) technology provides new possibilities within this industrial field. The Author explores state-of-the-art aluminum rod equipment and the range of application for the C.C.W. technology which allows the production of 1xxx - 2xxx - 3xxx - 4xxx - 5xxx - 6xxx - 7xxx - 8xxx series aluminum alloys for many industrial and specialty applications.
