(Summary description)

Information

 

Permo alloy refers to fe-Ni alloy with nickel content in the range of 30~90%. It is a very widely used soft magnetic alloy. The commonly used alloys are 1J50, 1J79, 1J85 and so on. Through the appropriate process, can effectively control the magnetic properties, is a typical functional material.

 

Characteristics of this kind of material:

  • High permeability;
  • Low coercivity;

  • High saturation magnetic induction intensity;

  • Curie temperature is high;

  • Good corrosion resistance;

  • Good processing performance; 
Application: mainly used in alternating magnetic field, used in aviation industry to manufacture electronic components with high sensitivity, fine size, small size and low loss at high frequency. Widely used in telecommunication, measurement and control system.

1.    The call of new technology

Although Permo alloy has significant effect and special application in precision components of aerospace industry, the traditional process of "smelting - rolling - heat treatment - finishing" has long production cycle and low pass rate. Coupled with the increasingly fine, lightweight, complex and integrated structure of space vehicles, the disadvantages and bottlenecks of traditional technology are increasingly prominent. Therefore, it is urgent to improve the traditional technology.

The stars don't ask the traveler, urged the horse forward. Grasps "the troops did not move the paper, first" concept, xin jing r&d team actively, forge ahead, and has organized a variety of brands of permalloy constituency laser melt forming technology research, a large number of experiments and tests, successfully conquer the permalloy melting and forming technology of laser district the microstructure of the print density, excellent mechanical properties, High dimensional accuracy, and successfully used in a certain aerospace product.

The following are the research results of 1J50
