C28000 copper sheet contains 60% copper and 40% zinc. The significance of this alloy lies in its color, which is essentially that of architectural bronze.The metallurgical structure of alloy No. C28000 consists of a large number of beta grains, making it harder and tougher than brasses with lower zinc content.C28000 hardens very quickly, making it less suitable for cold working. However, it can be easily bent or molded.

FAQ
What problems are likely to occur in the processing of C28000 copper plate?
C28000 copper plate is prone to curling problems during processing due to the inherent nature of the material and the stress imbalance during processing. In order to solve this problem, you can appropriately reduce the processing speed during processing, increase the cooling time of the material, or use a suitable roller for processing, making the stress distribution more uniform.
C28000 copper plate in which environmental conditions are easily damaged?
C28000 copper sheet is susceptible to corrosion in acidic environments where amino acids and sulfides are present, as well as in environments with high temperatures and high humidity. Therefore, when using C28000 copper sheet, special attention needs to be paid to whether its working environment contains these factors that may lead to corrosion.
What are the precautions for soldering C28000 copper sheet?
When welding C28000 copper plate, you need to use suitable welding rods and welding methods, otherwise the welding quality will be easily affected. Incorrect welding methods may lead to problems such as insufficient strength or cracks in the welded joints.
