Yeah I did have an idea that it is much more expensive than more common materials but the purpose of the parts is for adding weight. The specific use is in a radio controlled model, it's common practice to add weights and brass is the material most commonly used, stainless steel is starting to pop up and I'm assuming that's due to the price of brass....

I've got no idea of the manufacturing process out of the design software so wouldn't even know where to start as far as getting/pricing material goes....
