Title: Innovations by Jeffrey J Wiesner in Aluminum Alloys
Introduction
Jeffrey J Wiesner is a notable inventor based in Maryville, TN (US), recognized for his contributions to the field of aluminum alloys. With a total of 2 patents, Wiesner has made significant advancements that enhance the quality and performance of aluminum materials.
Latest Patents
Wiesner's latest patents focus on aluminum alloys that exhibit improved cast surface quality. These aluminum alloy compositions incorporate small amounts of calcium, which lead to enhanced surface properties. The inclusion of calcium, along with up to 0.25% grain refiners, alkaline earth metals, transition metals, and/or rare earth metals, results in a notable improvement in appearance, a substantial reduction in surface imperfections, and decreased surface oxidation in cast ingot aluminum and aluminum alloys. Remarkably, these additives have been found to eliminate vertical folds, pits, and ingot cracking across various casting techniques. The enhancements also improve the reflectance of the ingots, allowing them to be processed directly from the casting without the need for surface conditioning, such as scalping. Furthermore, Wiesner has disclosed a method for improving surface properties and preventing imperfections and cracking in cast aluminum alloys by adding calcium to a molten aluminum alloy that is free of beryllium.
