The loop frame is an important part of the loop in electronic components. Copper and 42%
nickel alloy materials are used competitively, and the proportion of use is determined by the processing of copper and nickel alloy raw materials. Because no chromium is added to the 42% nickel alloy, it is not a stainless steel but a high-nickel material. It is generally manufactured in stainless steel production plants because it is close to stainless steel.
The reason for the application of 42% nickel alloy is its superior electrical conductivity, which has the same characteristics as copper. A long time ago, stainless steel was also used as the wire frame. Because the chromium oxide film deteriorates the electrical conductivity, it is no longer used as a high-tech component.
The 42% nickel alloy is produced in the stainless steel production plant with a thickness of about 10-20 microns, and the parts processing plant cuts the plate and coil into strip coils with a slitting machine, and then stamps them in the wire frame processing plant , Etching processing plants can use etching technology for processing. It is difficult to blank small parts using a stamping machine. In recent years, precision stamping technology has been greatly improved. When the price of nickel alloy raw materials rises, the price of leftover materials is also high. Therefore, compared with the etching process, precision stamping still has an advantage in cost
