0.035mm * 520mm High Precision RA Copper Foil For Transformers
Produict Information :
- Size: 0.035x520x1000mm
- Chemical composition:
- Cu + Ag: 99.90 ,Bi: 0.001 ,Sb: 0.002 ,As: 0.002 ,Fe: 0.005 ,Pb: 0.005 ,S: 0.005 ,
- Mechanical properties:Tensile strength (Rm/MPa) 295 Min
- Rockwell hardness (HRF) 65 Min
- Elongation (%) 3 Min
Key Features:
- Cuts with scissors or paper cutter .
- Can be hammered, texturized or punched.
- Thick enough, so when glued to a backing-board, wood grain does not show through .
- Often used for punching, scrapbooking and other paper crafts.
- Has a wide range of applications based on workabilty and beauty.
- Excellent for tooling and will dent easily with a light touch but will not hold its shape under pressure.
Advantages :
- Rolled Copper Foil has extraordinary strength, bendability, ductility and lustrous surface, plus its excellent mechanical capacity, makes it irreplaceable as a raw material. Especially when used for transformer, Copper Flexible Connector, CCL.
- Soft temper are particularly strong demanded since it has wide range of use. For transformer, it need soft cooper foil to avoid high resistance and good heat radiating when it work.For copper flexible connector , it prefer soft copper because it has good extension and bendiablity. And for CCL,FCCLand PCB useage, the copper they needed will depending on the surface roughness. But for decorating and some other application, they need the copper to be hard and then it will not be out of shape when after a period of time
