Copper bendingMinifaber has over 50 years of experience in the metalworking field and is fully equipped to provide a complete and precise copper bending service, exactly as requested by the customer.
Copper bending, compared to other metals’ bending operations, is made quite easy by the physical composition of copper and its alloys. In fact, copper possesses a few characteristics that make it a top choice for bending operations, and put it among the most used materials in many different industries, despite of its high cost. These features are:
- Malleability: copper is a very soft metal by nature, which makes it extremely easy to bend;
- Conductivity: copper is a great electrical and heat conductor;
- Resistance to corrosion: copper has a great level of resistance to corrosion, thanks to a film that is created on its surface when it gets in contact with air.
However, the fact that copper is so versatile and easy to work with, doesn’t necessarily mean that copper bending is an easy operation. In fact, there are a few things that need to be taken under careful consideration before going forward with a copper bending operation.
How to provide a successful copper bending service
Copper is extremely soft, which means that it’s also very delicate and needs to be handled with care. Poor and inappropriate handling can risk damaging the material. So, in order to provide an excellent copper bending service, there are two things that need to be carefully observed:
- Cleanliness: the tools and work surfaces employed for copper bending need to be thoroughly cleaned before use, or exclusively dedicated to copper bending operations. This is because contaminated copper can be the cause of cracking and porosity during the bending treatment, and corrosion resistance can also be affected negatively.
- Bend radius: you can’t bend copper in just any point of the sheet. If you bend to a too sharp inside corner, you’ll be adding a lot of internal stress, which can result in cracking the material at the bend or weakening it to the point where it’ll break with minimal force. The solution to avoid breaking and guarantee a successful copper bending operation is to respect this simple rule: the inside bend radius should always be equal to the thickness of the copper sheet that is being bended.
