3. The "one step away" from laboratory to industrial production has taken desetljeća
In the past nearly a sto godina of istraživanje i razvoj, aliako ljudi have discovered that copper-željezo legure have a variety of excellent properties and broad application prospects, due to the poor compatibility between copper and iron, liquid copper and iron have a separation phenomenon that is nekompatibilno with each other. Iron alloys are known as the "oil" and "water" of metal materials. Therefore, copper-iron alloys s real use value have not been proizvedeno. Međutim, znanstvenici okolo the world have not stop researching copper-iron legura.
The most research on copper-iron legura in the world is in Japan, with more than 30 years of research experience, uglavnom focusing on alloy preparation technology and market applications, such as new energy auto parts, klip heads, electro control box for electromagnetic shielding. Materials, brake discs, etc.; new medical machine manufacturing, shielded boxes, shielded rooms, sanitary clothing, etc. ; nova generacija elektronička komunikacija polje, zaštita Materijali ZA KOMUNIKACIJA BAZA stanice, termalne difuzijske Materijali, KONEKTORI, etc.; i Various Types of Electromagnetic Shielding for Aerospace Wires, zavarivanje štapovi for brod propeler popravak, Toplina Disipacija Kalupi, električno pražnje obrada žice i ostala polja. Međutim, the industrial production of copper-željezo legure has not Been Truly Realed.
