Copper has been the most common alloying element since the early days of the aluminum industry, with numerous copper-dominant aluminum alloys developed for various applications. These alloys typically fall into distinct compositional groups containing 4-14% copper, often with additional elements like magnesium, silicon, manganese, and nickel.
Aluminum castings have played an integral role in the aluminum industry since its inception in the late 19th century. The first commercial aluminum products, such as cooking utensils and decorative parts, highlighted the novelty and utility of this versatile metal. Over time, aluminum casting has evolved to meet complex engineering demands, driven by advancements in alloy development, melting techniques, and casting processes.
Aluminum Bronzes: Part One
Aluminum bronze is a type of bronze in which aluminum is the main alloying metal added to copper. A variety of aluminum bronzes of differing compositions have found industrial use, with most ranging from 5% to 11% aluminum by weight, the remaining mass being copper; other alloying agents such as iron, nickel, manganese, and silicon are also sometimes added to aluminum bronzes.
