Brass allows the quality of copper to get full play, so the use of carved copper plate is more and more widespread. Below, Xiaobian to say what are the advantages of using it?

First, the structure is stable. Because of high strength and good toughness, the overall structure of brass is very stable, so that the application of carved copper plate is stable and reliable, and the function has been greatly played.

Two, very good performance. Brass can improve the strength and toughness of copper, ductility, can well resist the adverse influence of various external factors, prolong the service life of carved copper plate.

Three, long service life. Brass plate through processing, so that many advantages of copper can be more good play, reduce the adverse influence of external factors, longer service life.

Commonly used process heating speed is fast, easy to cause the inner and outer ring heating and insulation time is inconsistent, resulting in unstable performance, carved copper plate inner ring due to too long insulation time and hemp, outer ring due to insufficient insulation time caused by high tensile strength, low cup process value. By changing the heating process curve, the new process slows down the heating rate when rising to 350℃, so that the temperature in the later stage uniformly rises to the insulation temperature, so that the upper and lower in the furnace, the inner and outer rings of the material insulation time is consistent, so that the product performance is uniform.

Generally, in the case of the same holding time, the higher the holding temperature, the lower the tensile strength of the material, the higher the elongation, although the cup value is high, it is easy to hemp, easy to process. Therefore, the new process in the five rolling process of the insulation temperature are adjusted, through many tests, the ideal effect is in the three rolling process of annealing insulation temperature is increased 10 ~ 15℃ than the original process, increase the amount of pressure, and in the finished annealing stage of the insulation temperature is reduced 10℃, in order to ensure the tensile strength of the engraved copper plate, elongation and cup value performance requirements, the test has reached the expected purpose.
