No pores, trachoma, looseness, good electrical conductivity, high precision of the surface of the electro-eroded mold, after the heat treatment process, the electrode has no directionality, suitable for precision punching, fine punching, and has good thermal conductivity, processability, ductility, and anti-corrosion properties. Corrosion and weather resistance, etc. It has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazed.
- It has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and fiber welded. Contains few impurities that reduce electrical conductivity and thermal conductivity. A small amount of oxygen has little effect on electrical conductivity, thermal conductivity and processing properties, but it is easy to cause "hydrogen disease". It is not suitable for processing (annealing) in a high temperature (such as >370°) reducing atmosphere. Welding, etc.) and use.
Purpose of copper strip:
The use of red copper is much more extensive than that of pure iron. Every year, 50% of the copper is electrolytically purified into pure copper, which is used in the electrical industry. The red copper mentioned here really needs to be very pure, with a copper content of more than 99.95%. A small amount of impurities, especially phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Oxygen in copper (a small amount of oxygen is easily mixed during copper smelting) has a great influence on conductivity, and copper used in the electrical industry must generally be oxygen-free copper. In addition, impurities such as lead, antimony, and bismuth will make the copper crystals unable to bond together, causing thermal embrittlement, and will also affect the processing of pure copper. This kind of pure copper with high purity is generally refined by electrolysis: impure copper (that is, blister copper) is used as the anode, pure copper is used as the cathode, and copper sulfate solution is used as the electrolyte. When the current is passed, the impure copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. The copper refined in this way has a purity of 99.99%. Red copper is a relatively pure type of copper, which can generally be approximated as pure copper. It has good electrical conductivity and plasticity, but its strength and hardness are relatively poor.
