Probe Pin Materials
We strive for materials that combine high hardness, low resistance and excellent linearity.
Probe pin materials are used in inspection equipment for semiconductor wafers and devices.
We are engaged in manufacturing and developing new materials for probe pins that emphasize high hardness and low resistance. We offer a wide range of products, including those with a hardness of 500HV or higher, and we provide products tailored to meet our customers' needs.
We provide linearly processed standard-length products and short-cut pins.
