1J80 It is a kind of permalloy, which belongs to the functional alloy with high initial magnetic permeability and has a density 8.50 g/cm3 The Curie temperature is 330 C, its remarkable characteristics of high permeability, low coercivity, suitable for the production of transformers, chokes, magnetic heads, magnetic shields, magnetic modulators and other devices, in telecommunications, instrumentation, telemetry, remote control and other systems are widely used.


1.    The Call of New Technology

Permalloy plays an important role and significance in the aerospace industry precision components, with the increasing refinement of the structure of the spacecraft, lightweight, structural and functional integration, the application of some thin-walled, lattice and other complex components of the growing demand, which poses a challenge to the traditional process.Selective Laser Melting Technologyhasnon-die forming,High dimensional accuracyandgood metallurgical qualityIt is very suitable for the manufacture of such parts, with significant advantages.

If you sail against the current, you will retreat if you do not advance. Xin Jinghe R & D team took the initiative to forge ahead and organized and planned permalloy.1J80A large number of experiments and tests have been carried out, and the laser selective melting forming process has been successfully overcome.metallographicdense tissue,excellent mechanical properties,High dimensional accuracyand successfully used in a space product.


2.    1J80Material characteristics and printing difficulties

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