You have talent, you have material, you have a future | Permo alloy (2)

(Summary description)

Information

Permo alloy has been included in the list of printable materials

1 j80 is one of the permalloy, belongs to the high initial permeability function alloy, density of 8.50 g/cm3, Curie temperature is 330 ℃, its significant features for high permeability, low coercivity, applicable to the production of transformer, reactor, magnetic head, magnetic shielding device, magnetic modulator devices, such as in telecommunications, instrumentation, remote sensing, remote control, etc are widely used in the system.
 

1.    The call of new technology

Permo alloy plays an important role and significance in precision components of aerospace industry. With the increasingly fine, lightweight and functional integration of aerospace structures, the application demand of some complex components such as thin-wall and lattice is increasingly strong, which poses a challenge to the traditional technology. Laser selective melting technology has the characteristics of no mold forming, high dimensional accuracy and good metallurgical quality, which is very suitable for the manufacturing of this kind of parts.

He who does not advance loses ground. Xin jing r&d team actively, forge ahead, and organize the permalloy 1 j80 constituency of laser melt forming technology research, a large number of experiments and tests, successfully conquer the constituency laser melt forming process, the microstructure of the print density, excellent mechanical properties, high dimensional accuracy, and successfully used in a certain space products.    

2.    1J80 material features and printing difficulties

The technical difficulties of this material are: the residual stress is large in the printing process, and the magnetic properties are very sensitive to the heat treatment process and residual stress. By optimizing the printing process parameters and process route, the problem was solved successfully.
