New policies tackle industry problems; tech innovation becomes key
On July 28, 2025, the Ministry of Industry and Information Technology held a national meeting for industrial and information technology departments. It made clear that one of the key tasks for the second half of the year is to strengthen the results of regulating "involution-style" competition in the new energy vehicle industry. This industry shake-up, caused by unordered price wars, has led many companies' profit margins to drop below 5%. Relays, as Pure Iron Core for EV Relays of electric vehicles, now face unprecedented pressure to upgrade their supply chains.
Relay technology is upgrading fast
Big improvements in electromagnetic performance
Electrical pure iron DT4 series (like DT4E) for Relay Pin Core has a maximum magnetic permeability of over 15,000, 10 times that of ordinary silicon steel. This material can reach a magnetic induction intensity of 1.5T under a 200A/m magnetic field. This lets relay coils have 30% fewer turns, reducing copper loss and size.
Processing technology solves manufacturing problems.
DT4C pure iron for Relay Rod can be made into 0.1mm ultra-thin strips through cold rolling. With precision stamping, it can produce micro cores with an accuracy of ±0.01mm. After heat treatment, its coercivity can drop below 32A/m. This ensures that relay contacts separate within 1ms after power is cut, completely solving the sticking problem of traditional cores.
