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.

So uhm can u basically make a bulletproof chassis for a homemade tank with this?
I HAVE TO MAKE A QUESTION ABOUT THE ALUMINUM. THERE ARE VARIOUS TYPES OF ALUMINUM. WHICH ITEMS ARE MADE WITH THE MOST PURE ALUMINUM?
Thank you for the video. Do you not use Propane? Why not?
What the difference between: 88% Cu + 12% Al and 89% Cu + 11% Al
Is it possible to do the test of which ratio will yield the best results? Thank you, i subscribed!
Hi friend again: how are u? Look I never machined with the lathe aluminum bronze, people says that is toooo hard. I have like 50kg of cooper and my idea is make some alu bronze, if I put 5% or 6% aluminum do you think that can be more softer but better to machine puré cooper. Compared with steel 1045 without temple how hard is? A big hug
90% Copper and 10% Aluminium is better. I ve read that it only mixes good with 6% Aluminium or 10%.
how strong is the alum brass . can you make machine parts out of it and will they hold up as steel?
i read on one site that said this was "white brass" but i guess they're mistaken?
Great vice
“How hard is it?”

“Is very hard”
