DIN Ecu-58 Pure Copper Seamless Tube With Great Conductivity In Electricity And Heat
1. Description
DIN Ecu-58 American Standard pure copper has good electric conduction, heat conduction, corrosion resistance and processing performance. Pure copper pipe can be welded and brazed. It contains little impurities to reduce conductivity and thermal conductivity, and trace oxygen has little effect on conductivity, thermal conductivity and processing, but it is easy to cause "hydrogen disease", so it is not suitable for processing (annealing, welding, etc.) and use in high temperature (such as > 370 ℃) reducing atmosphere.
