In the mid-1960s two giants of the aluminium industry, the Bratsk and Krasnoyarsk aluminium smelters, which each had the capacity of 1 million tonnes of metal per year, were commissioned in Siberia. The prophecies of Dickens, Verne and Richards have come true! Technical progress in the industry will continue and basic processes will improve creating new alloys. It produced only 20-25 kg of aluminium per day in the first few months, but quickly accelerated to 240 kg daily by 1890. on Who discovered Aluminium? In fact, there were so many swirl marks, the finish only magnified the problem. The first aluminium products are considered to be medals made during Napoleon III's reign. A year later Tobler started to use foil for chocolate packing, still used to this day, even the famous Toblerone bar is wrapped in it too! Figure 8.1. Aluminium oxide A type Shank dia.
