Aluminum silver is a master alloy that can be formed in various forms including sheets, discs, foils, rods, tubes, ingots and powder. It can be used as a hardener, grain refiner and for enhancing the physical and mechanical properties of metal alloys by controlling the dispersion of crystals.
High purity aluminum silver is available in standard ratios of Al:Ag; custom alloy compositions are also offered. Advanced chemical analysis is performed for all products by X-ray fluorescence (XRF), glow discharge mass spectrometry (GDMS) and inert gas fusion.
Origins and Early History of Aluminum
The metal we know as aluminum was discovered in 1825 by Danish chemist Hans Christian Oersted and German scientist Friedrich Wohler. They found small globules of what looked like silver in a pond that contained alum, the name for an aluminum-based salt.
In the mid-1800s, it was more expensive than gold but far less rare. It was the third most common element in the earth’s core (also found in gems and clay), but it had to be extracted from bauxite ore by a process that wasn’t economical.
In 1857 a Parisian named Henri Sainte-Claire Deville invented an inexpensive method for reducing bauxite ore to aluminum. It was so effective that the metal became more precious than silver and was a must for Napoleon III, who had cutlery made of it only for his most distinguished guests.
