What type of material is “MOFC-HR”?
MOFC-HR (Heat Resistance) is a copper material that overcomes the shortcomings of conventional oxygen-free copper, such as limited strength and vulnerability to heat. This is an unprecedented oxygen-free copper with the world’s highest level of strength and heat resistance!
*MOFC stands for “Mitsubishi Oxygen Free Copper.” The MOFC series includes a wide variety of oxygen-free copper materials including MOFC-HR.

Adding a small amount of magnesium significantly improves heat resistance and strength while maintaining conductivity!
We discovered that by adding a very small amount of magnesium during the production of oxygen-free copper, it was possible to segregate sulfur, an impurity that has a negative effect on conductivity, and slightly increase conductivity.Using this effect, we improved heat resistance without lowering conductivity by controlling the addition of magnesium, and by increasing strength at the same time, we created MOFC-HR!
【Area s of applications】
Electric vehicles/Next generation energy
MOFC-HR is expected to play an active role as a key material for electrical components that require large current capability and high heat dissipation in harsh environmental conditions. It can also withstand heat treatment during manufacturing and has the strength required for size reduction, allowing for a wider range of processing methods.
It is a groundbreaking material that overcomes the weaknesses of oxygen-free copper!
