Beryllium copper wire is widely used in our industrial manufacturing. It has gained the favor of many manufacturers by virtue of its material performance. The use of this material is often accompanied by some improper behavior, affecting its own performance. Below to understand the surface treatment method and function of beryllium copper wire, I hope to be useful to you.

Any grease on the surface of beryllium copper wire will cause surface stains or affect subsequent heat treatment, plating and welding. Once stamping oil is used in stamping, it must be degreased after stamping. If the chlorine or sulfur content of stamping oil is high, degreasing methods should be carefully estimated or avoided.

During heat treatment of beryllium copper wire, oxide film is often produced on the surface. The oxide film must be removed before further plating and welding. The usual cleaning method is to disperse the product in 20% dilute sulfuric acid and heat it to 50-90 degrees Celsius. It is also possible to immerse beryllium copper wire in the solution overnight at room temperature, since the oxide film caused by grease contamination cannot be removed by pickling, so it is degreased before proceeding to harden.

In addition, beryllium copper wire surface treatment includes rust protection. Benzene moll and three nitrogen commonly used to prevent air caused by copper alloy discoloration, it forms benzene moll and three nitrogen doles in copper alloy surface, insoluble in water and other solvent characteristics, it does not affect the pretreatment process of electroplating, because it at 100 degrees Celsius or high temperature sublimation, so the aging hardening treatment has no effect.
