DIY Aluminum Bronze. One of the hardest bronzes!

For one of future projects I need hard bronze, that's why I decided to make Aluminum Bronze. This bronze is one of the hardest! 

This bronze will consist of 88% of copper and 12% of aluminum. Melting process is simple. At first I need to melt copper. So when I reach the temperature 1100-1200 C, I'll add aluminium. Finally, I suppose to get 2 kg of hard aluminum bronze. 

From Wikipedia:
Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper, in contrast to standard bronze (copper and tin) or brass (copper and zinc). A variety of aluminium bronzes of differing compositions have found industrial use, with most ranging from 5% to 11% aluminium by weight, the remaining mass being copper; other alloying agents such as iron, nickel, manganese, and silicon are also sometimes added to aluminium bronzes.
Aluminium bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion. They are also resistant to corrosion in sea water. Aluminium bronzes' resistance to corrosion results from the aluminium in the alloys, which reacts with atmospheric oxygen to form a thin, tough surface layer of alumina (aluminium oxide) which acts as a barrier to corrosion of the copper-rich alloy. The addition of tin can improve corrosion resistance.
