Copper foil is made by beating copper with a certain proportion of other metals, and is the most widely used decorative material. So how much do you know about copper foil? Do you know which items need to be tested for copper foil? Are there any testing standards?

Testing items:

Thickness testing, surface copper powder testing, performance testing, oxygen content testing, electrical resistivity testing, double conductive copper foil, mechanical testing, anti oxidation testing, factory testing, bending resistance testing, etc.

Testing standards:
