Round silver wire
Process introduction
The preparation of silver wire is to melt the silver plate, turn it into liquid silver, and then pour it into a column, through a large extrusion machine extrusion into a large size wire.
Large specifications of wire rod through the drawing machine's standard drawing die to produce the required specifications, the general specifications are from 0.5mm to 4mm.
The production cycle of this kind of silk material is relatively short, generally 5 to 7 days can be completed
Performance introduction
The Round silver have high electrical and thermal conductivity, low and stable contact resistance, good soldering and processing properties. Fine-grained silver greatly refines the grain structure of the material due to the addition of a small amount of nickel in the silver. The mechanical strength and temperature resistance of the material are higher than that of silver under the condition that the contact resistance is almost the same. Therefore, the resistance to fusion welding and arc burning resistance is better than that of silver.
Application area
Due to the high cost of silver, and the performance can not meet a variety of test conditions, so the market use of silver or fine silver is relatively small, is generally applied to small current products
