Anti-wear, anti-shock cutting tool "IGETALLOY"

Responding to the needs for high-speed, high-efficiency and high-precision machining, "IGETALLOY" insert works as a mechanical interface between machine and material, playing a prominent role in the fields such as cutting and plastic working.

Key material in various fields

Large-sized synthetic monocrystal diamond realizes stable supply of high-quality diamond products. The stable quality makes it ideal material for industrial applications. Manufactured in the facilities under thorough quality control, Sumitomo Electric's synthetic diamond guarantees consistent high quality.

Enhances the machining efficiency for machine parts and molds

Sumitomo Electric's end mills and drills are made from an alloy that has hardness next to diamond and the steely toughness. A wide array of grades is available for various applications.

Ultra-small-diameter drill for drilling of printed circuit board

Sumitomo Electric's microdrill has proprietary drill tip shape and resolves problems such as rough hole wall. A wide array of grades is offered for various printed circuit materials and diverse machining conditions.

High-precision, high-strength machine parts

Use of rapidly-solidified aluminum powder provides high level of strength, wear resistance, and heat resistance that cannot be achieved with molten alloy. Compared with conventional aluminum products, our products excel in machining characteristics and thereby meet demands for weight reduction of automotive parts.

Heat sink for high-power semiconductor devices

CMSH is a combination of two or more different metals, such as copper-tungsten, made by metallurgical process. This product has excellent heat conductivity and features thermal expansion coefficient close to IC chips and peripheral materials.

Tool for high-density packaging of IC chips

In TAB bonding, bonding tool is used to thermally bond the lead wires to an IC chip. Sumitomo Electric's bonding tool, which has a tip made of chemical vapor deposition (CVD) diamond or other material, supports low-cost and high-reliability packaging.

Heart of large building structure

Epoxy-coated steel wire is an internal reinforcement for prestressed concrete. It has high-strength and small cross-section area, and is cost efficient because it does not need coating process. The DYWIDAG method, which Sumitomo Electric holds the right in Japan to implement, is adopted to use prestressed concrete in many bridges and other large structures.

Steel wire for springs that is usable under high stress condition

This steel wire is used for automotive valve springs and torque converter springs, which are required to have good fatigue resistance under high stress conditions. As automobiles are becoming more lightweight and fuel-efficient, the demand for oil-tempered wire with higher fatigue resistance is increasing and Sumitomo Electric's proprietary steel wire is hence used widely.

Contributes to improved driveability and comfortable ride

Steel cord is used for the reinforcement of radial tires. Sumitomo Electric's patented steel cord features excellent adhesiveness with rubber, and satisfies not only the basic properties required for automobile tires, but also more advanced and diversified needs of customers.
