Copper

A brown, shiny metal used heavily in electronics, a great conductor of both heat and electricity. Has a very high thermal conductivity, easily the best for common metals. It is a spawnable non-flammable solid.
Here is a list of possible sizes that reach the maximum malleability (4096) that have integer components: 1x2x2048, 1x4x1024, 1x8x512, 1x16x256, 1x32x128, 1x64x64, 2x2x1024, 2x4x512, 2x8x256, 2x16x128, 2x32x64, 4x4x256, 4x8x128, 4x16x64, 4x32x32, 8x8x64, 8x16x32, 16x16x16
At its default size (4x1x2) it has a durability of 8, at its maximum size it has a durability of 65.
By default, its colour is #da8541.
