Description of 5N copper and 5N copper products:

• Copper is a chemical element with symbol Cu and atomic number 29. It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color.
• Cu granules are an ideal metal evaporation material for PVD. Meanwhile, they can also be used for high purity metal alloy smelting, high purity metal compound preparation, crystal preparation and other fields. Copper rod is most widely used and has the largest consumption amount in electrical and electronics industry, taking more than half of the total consumption. Used for manufacture of all kinds of cables and wires, motors and transformers, switches and printed circuit board; For manufacture of industrial valves and fittings, meters, sliding bearings, molds, heat exchangers and pumps, etc. in machinery and transport vehicles.
• Features: high purity, fine, low oxygen content.Pore-free, trachoma, osteoporosis, and excellent electric conductivity, electric erosion of the mold surface of high precision, the heat treatment process, the electrode omnidirectional, suitable for fine, fine, good thermal way, processability, ductility, corrosion resistance and weather resistance, etc.

 Packaging of copper cathode sellers:

Inner-packing: vacuum-packed,wrapped with styrofoam.

Outer-packing: carton/plywood.

Shipping of copper cathode sellers:
===========================================================================

We can supply you the translation methods whatever you want.

--By express (DHL/Fedex/etc.)

--By Air to your nearest Airport

--By Sea to your nearest Seaport

--By the sellers' shipping agent

 The first step ,our Technical put the materials into Vacuum Induction Melting produce.

The second step, engineering team analysis the chemical of materials.

The third step,Our team will put them into the rolling / annealing produce.

The fourth step,them are put into the machining process.

And then ,keeping their dimension.
