How Copper Flat Bars Are Made
Making copper flat bars involves several careful steps. First, pure copper is melted in a furnace. The melted copper is poured into molds to make big slabs. These slabs cool down before the next step.
The slabs are rolled to get the right size and shape. This rolling, done hot or cold, makes the surface smooth and even. After rolling, the bars are cut to the needed lengths.
Lastly, the bars might be polished or coated to look better or work better. These steps ensure the bars meet standards like ASTM B187. Then, they are ready for use in many industries.
