/diy/ - Do It Yourself

I’m working on an electromagnetic accelerator, a mix of a coil gun and rial gun. I finished the coil gun part and it fires at a respectable 110fps already and I expect to get another 30fps out of it with some fine tuning. However, the third stage of the accelerator is a rail gun and I need a very hard and conducive metal for it. I wanted to use copper beryllium plates for this since it fits the bill (very conductive and will be able to handle the arcs/heat okay), but I’m having a hard time finding it in 2mm flat bar in the USA. I found some 2mm round bar that might work but it’s from China and I don’t want shitty Chineseium metal.
