Copper Strip & Copper Foil C11000 C10200 C12000 Cu-of Cu-Frhc Cu-Frtp Cu-DLP Cu-Dhp

The copper foil is of a low surface oxygen characteristics, can be attached to a variety of different substrates such as metal, insulating materials, etc., within a wide temperature range. Mainly used for electromagnetic shielding and antistatic, conductive copper foil on the substrate surface, combined with the metal substrate, has an excellent conductivity and electromagnetic shielding effect.It can be divided into: self-adhesive copper foil, copper foil of the double glue,single copper foil, duplex copper foil.

Properties and chemical composition

Good conductivity and heat conduction. Corrosion resistance and machining properties, can be welded and fiber welding. Contains less impurities that reduce conductivity and thermal conductivity, and trace amounts of oxygen to conductivity. Thermal conductivity and processing performance is not affected, but easy to cause "hydrogen disease", not at high temperature (such as gt; 370°) in reducing atmosphere (annealing. Welding, etc.) and use.

The use of red copper is much more extensive than pure iron, 50% of the copper is purified for pure copper by electrolysis every year, used in the electrical industry. Here said copper, really to be very pure, copper 99.95% or more, a very small amount of impurities, especially phosphorus, arsenic, aluminum, will greatly reduce the conductivity of copper. Oxygen in copper (copper smelting is easy to mix with a small amount of oxygen) has a great impact on conductivity, copper used in the electrical industry must generally be anaerobic copper. In addition, lead, antimony, bismuth and other impurities will make the crystallization of copper can not be combined together, resulting in hot brittle, will also affect the processing of pure copper. This kind of pure copper with high purity is generally refined by electrolysis: the impure copper (coarse copper) as the anode, pure copper as the cathode, and copper sulfate solution as the electrolyte. When the current passes through, the impurity copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. Copper obtained by such refinement; The purity can reach 99.99%. Copper is a relatively pure copper, generally can be approximately considered to be pure copper, electrical conductivity, plasticity are better, but the strength, hardness is worse
