If you want to control the quality of your alloy, it is best to make it yourself. For bronze it's very easy, just melt copper and tin together...
Yes, but not in any proportion.
Bronze is composed mainly of copper with between 5 and 25% tin. For the mechanical parts we will use 8 to 15% tin, for the bells we need between 20 and 25%.
The more tin the better the flow, but too much tin reduces the mechanical characteristics and increases the fragility, on the other hand the sound is better for the bells.
For my parts, I chose to use 12% tin, in other words it is CuSn12 bronze.
Important point, the percentages are relative to the masses of each component, so easy to dose with a simple kitchen scale.
