Copper alloys in aquaculture copper sheathed hulls. Many complicated factors influence the environmental performance of copper alloys in aquaculture operations. A technical description of antibiofouling mechanisms, fish health and welfare, fish losses due to escapes and predator attacks, and reduced life cycle environmental impacts is summarized in this reference. Copper–zinc brass alloys are currently (2011) being deployed in commercial-scale aquaculture operations in Asia, South America and the US (Hawaii). Extensive research, including demonstrations and trials, are currently being implemented on two other copper alloys: copper-nickel and copper-silicon. Each of these alloy types has an inherent ability to reduce biofouling, pen waste, disease, and the
Wabash Alloys Locomotive Wabash Alloys Locomotive The Wabash Alloys Locomotive is a GE 25-ton diesel-electric locomotive built in 1940-43. Little is known about its early life, but from around 1970, it worked at Wabash Alloys, a producer of aluminum alloys, at Haskell, Arkansas. It eventually became surplus to the company's needs and they donated it to the Arkansas Railroad Museum at Pine Bluff, Arkansas on March 8, 2003. The 25-ton model was the smallest locomotive in the GE range in the 1940s and 50s. It was designed for the small industrial user. With and of tractive effort, it could pull half a dozen
