Circuit application of copper mine

Hello, I’m from Taiwan, so please forgive me if the following English is not good

My main thing is that I hope that the copper mine can be made into copper bars

• What is the use of copper bars?

Do you often use the redstone mechanism.When two different redstone circuits collide and cause the mechanism to fail or make mistakes. If the copper bar and the redstone do not touch each other on the same plane at this time, the redstone mechanism will be more convenient to make and the size of the mechanism is also Can reduce

• Disadvantages of copper bars:

Of course such a magical thing has its own characteristics
1. He will rust, so he has to wax with honey
2. The copper bar cannot be bent, so redstone still needs to be bent at the bend (just like the power rail cannot be turned, it needs to be replaced by ordinary rails)

My suggestion is like this, I hope you can see and support
Because I thought about this idea for at least a week
