Providing Products That Support Next-Generation Technology, Worldwide
Copper & Copper Alloy Business
Increasing current production by 30% by enhancing facilities at each plant
Enhancing casting facilities
We enhanced the casting facilities of the plant to improve the system for producing copper billets and cakes, which are raw materials of wrought copper products.* Through this initiative, we will increase the production volume of copper billets and cakes.
*Wrought copper products: A group of products that have been processed from copper, brass, bronze, and copper alloys into plates, strips, tubes, rods, and wires.
Copper billets and cakes
Materials to produce wrought copper materials, such as copper tubes, rods, plates, and strips. Cakes with a square surface are suitable for plates and strips, while billets with a round surface are for tubes and rods.
Installment of cleaning machines, slitters, and packing machines
We will increase the production volume of rolled products by installing new cleaning machines, slitters, and other equipment. This will allow us to meet the growing demand for processed copper products due to the expansion of the xEV market.
Installing slitters and packing machines and enhancing tin reflow soldering lines
We will increase the production volume of rolled products by installing new facilities, such as slitters and packing machines. This will allow us to meet the growing demand for processed copper products used in automotive and other applications.
Copper plates and strips
These products are made by rolling copper cakes into forms of plates and sheets. Mitsubishi Materials boasts the top market share in Japan.
Electronic Materials and Components Business
Enhancing the system for producing components of semiconductor manufacturing equipment
Increasing the production volume of materials for replacement parts for semiconductor manufacturing equipment
We will expand the production of columnar crystal silicon and increase the number of produced ingots by 1.3 times by 2026 compared to 2021.
Columnar crystal silicon
Used as a material for components in semiconductor manufacturing equipment. Columnar crystal silicon excels in strength, machinability, and bendability, making it easy to process into various forms, including rings.
Production expansion of sealing products for semiconductor manufacturing equipment
By expanding the production volume through renovation of existing facilities and construction of clean rooms, we will aim to increase the sales of sealing products for semiconductor manufacturing equipment by about 1.5 times by 2025 compared to the sales in 2021.
Sealing products
These are produced for dry etching equipment, etc. used for semiconductor manufacturing. In addition to plasma resistance, they stand out in being free of PFOA, an organic fluorine compound, whose content amounts are governed by the EU REACH Regulation.*
*REACH Regulation: Regulations on the registration, evaluation, authorization, and restriction of chemicals set by the EU.
