Brass: CW614N – CW617N – CW618N – CW508L
Alloy composed of copper and zinc. Used in many different uses: the nuts and bolts to the lathe work, furnishing and naval, in the electric field for the holder, in the marine heat exchangers, the boxes of cartridges, coins, musical instruments.
The chemical symbol is CuZn.
Brass products are particularly suitable to be linked with other components such as lead, aluminum and nickel depending on usage.
