New materials to change the future suitable for the EV and 5G eraMTA Alloy Birth

We aim to create a Multi・Tool・Alloy that can be used in a variety of fields.

What’s MTA alloy?MTA alloy is the new alloy that have been told it is impossible.

The crystal structure of “Iron” and “copper” are different in the first place, and different specific gravity and melting points. Iron and copper don't mix no matter how much it dissolves, even if mixed, don't mix like water and oil, it is impossible even from the phase diagram of material called a material map.

It may have been long- standing dream of humankind that “if an alloy of iron and copper is made, what kind of characteristics will come out?”. Copper was the first metal that humankind got, then iron dominated the world. It's no wonder there are people like that, people who thought “let's mix” and “let's make an alloy” with metals that have been familiar to us for a long time.

If you follow the records in recent years, the development of iron-copper alloys has been carried out in the United States, Europe, and Japan since before World War Ⅱ. It is said that, Germany and the United States competed for the technology in World War Ⅱ. Then Olin company in the US. Has greatly excited the industry, they finally succeeded in mass production of “copper with iron = C1940” which is mixture of copper and iron up to 2.5% after World War Ⅱ. However, it has been the established theory that it was virtually “impossible” to mix any further since that time.

We succeeded in mass production for the first time in the world.It changed from impossible to possible that a special melting method.
The first step, the creation of “MTA9100”, a new alloy of 90% iron + 10% copper.

MTA alloy succeeded in developing “Iron” and “Copper” alloy in2016. There are many common senses about “melting” that melts metal. However, MTA alloy sought a new melting method that was not bound by this common sense, then finally, we completed the original melting method of alloying “Iron” and “Copper”.

It is easy to write in words, this is the melting method that we have finally arrived at by repeating the trial with reference to the data accumulated so far and the knowledge cultivated by our predecessors. Moreover, the fact that this alloy can be manufactured by melting in the atmosphere is also a great advantage in terms of mass production.

MTA alloy was named MTA after the acronym for a multi- use alloy [Multi Tool Alloy] by the composition ratio of iron and copper can be adjusted making it an alloy that is useful in various fields for each ratio.

The characteristics of iron and copper appear in a well-balanced manner."MTA-FeX" well-received as a beryllium copper substitute

MTA-FeX, which is being developed as an alternative to beryllium copper, is a hybrid alloy with a good balance between the mechanical properties of iron, such as hardness, strength, and heat resistance, and the functional properties of copper, such as thermal conductivity and electrical conductivity. In particular, because it is a ferrous alloy with strong copper alloy properties, it is recommended for use as a functional material rather than as a structural material. For details, please refer to "MTA-FeX" on the product page.

The demand for copper is increasing as we enter the EV and 5G society, and this has caused prices of various copper alloys to rise one after another. Please take this opportunity to consider replacing beryllium copper.
