Neither manufacturing know-how nor the mass production technology was not established yet though metal manufacturers had long been researching the copper-iron alloy. That was because copper and iron cannot be mixed by melting them due to the difference in their specific gravity. We, The Copper-iron alloys inc., succeeded in creating the copper-iron alloy without the segregation through its process of fusion-casting and forging-processing by adding special flux, the deoxidizer, etc. at the fusion of the metal.


Decide on CFA10 to 90 based upon the weight ratio of material. fusion forging

*cold rolling
It can be freely processed into a board, a bar, wire, etc.
