Causes of pits in brass sheet strip
It is believed that many people have encountered the surface of the brass plate or the brass sheet strip, which has been peeled or dented, which makes the strip unusable, It is a headache, because once there are pits or pitting on the surface, peeling will cause the whole plate to be useless. It will be a great waste for many units and the cost will be improved a lot! But what is the reason? Is there any way to avoid it?
The phenomenon of peeling, pitting and pitting occurs on the surface of cold rolled brass plate, one of the reasons is that it needs to pass many rolling processes. In any process, if the surface is not cleaned, there will be oxide attached to the copper plate surface. When the next rolling is performed, it will be pressed and rolled in the brass plate, which will cause the oxide to fall off when the finished copper plate is processed. Then the defects such as pits and pitting will be formed.
For a simple example, when rolling with a rolling pin, sprinkle a few sesame seeds on the cake surface, then the sesame seeds will be embedded in the cake, but if the sesame seeds fall off in the process of wrapping the cake, it will become a pit!
Another is more common, that is, due to the lack of tightness of packaging in the process of transportation, the gap between the brass plate and the brass plate is too large, so in the process of transportation, the vehicle bumps and other conditions, causing surface collision friction! Copper, especially brass, belongs to relatively soft metal. It is inevitable to leave ugly pits after heavy collision and friction. This reason is a property of the ugly pit left by pinching bread by hand.
