Silver Solder For Copper Pipe

Silver solder for copper pipe Silver solder for copper pipe will produce a skin effect when alternating current passes inside the conductor due to Lenz's law, that is, the current density on the surface is greater than the current density inside the conductor, which is equivalent to reducing the cross-sectional area of the conductor and greatly improving the conductor resistance. Therefore, if the surface of the conductor is plated with silver, the surface resistance can be reduced, thereby improving the conductivity of the conductor as a whole.

The electrical conductivity of silver is better than that of gold. The electrical conductivity of silver is the highest among all metals, higher than that of copper, but it is not widely used in electricity due to high prices. Radio-frequency engineering is an exception, especially in bands above VHF, where silver plating can significantly increase the overall conductivity of components and wires because the high-frequency current is concentrated on the surface of the conductor rather than inside it.

The effect of silver plating of copper solder reduces resistance, prevents rust, prevents oxidation of copper layer and reduces electrical conductivity. Bare copper wire is easy to oxidize, through tinning or silver plating treatment can reduce oxidation, improve the antioxidant capacity! Can also increase the weldability, easy to weld! Not only to improve its weldability, but also copper wire tinning can prevent the insulation rubber from sticking, the wire core blackened and brittle. Silver-plated copper wire is mainly used for rubber insulated mining cables, flexible wires, flexible cables and Marine cables as conductive wire cores, as well as for cable shielding braid layer and brush line. It can also be used in resistors and capacitors, photosensitive components, etc

The silver plating of copper pipe solder can be processed and derived from a variety of cables, such as power cables, communication cables, control cables, special cables, which are widely used in power, railway, communication, aviation, medical, transportation, construction, ships and other industries.

In terms of physical properties, the silver plating of copper tube solder has good electrical conductivity, thermal conductivity, high strength, corrosion resistance and high temperature stability.

Quality and control standards meet BS EN13601 ASTM B846 ASTM B624 American standard ASTM B105/624, European standard (EN13602), Japanese standard (JIS H3260), DIN CEN/TS 13388, BS EN 50149, GB/T 5231, GB/T 21652, etc.
