伸和商事 Company Overview

By maintaining a consistently abundant variety of stock, we can flexibly respond to our customers' needs! Cut products are available for purchase from just one piece or one sheet.

Our company has been a primary wholesaler specializing in unique non-ferrous metals, such as [phosphor bronze bars, nickel silver bars, and beryllium copper bars], since our founding in 1964. Since our establishment, we have always worked with a spirit of gratitude and challenge under the management philosophy of "coexistence and mutual prosperity." By maintaining a sense of gratitude, our actions and responses change. As a result, we believe we can grow into a company that earns the trust of everyone and society. Moreover, challenges often come with anxiety, but as the saying goes, "it's easier to give birth than to worry," taking that first step often leads to better outcomes than expected. We aim to continue challenging ourselves with a broad perspective and knowledge. While cherishing the core values of gratitude and challenge that are the foundation of Shinwa Shoji Co., Ltd., we will work together as a company to advance in the wholesale business. We look forward to a long-lasting relationship with you. 【Trading Manufacturers】 ■ Fujii Seisakusho Co., Ltd. (Major trading manufacturer) ■ NGK Insulators, Ltd.

Started stocking quick-cutting brass C5441B-H Φ1.0 centerless (high-precision grinding) material for inspection probe pins.

  • PRODUCT

Contact probes (semiconductor contact probes) are essential precision electronic components that guarantee the quality and performance of semiconductor devices during manufacturing and inspection processes. In response to the rapidly increasing demand for contact probes in semiconductor testing and other applications, we have begun to stock centerless materials with enhanced outer diameter precision. - Significant reduction in time until processing begins. - Even for rare materials that require guaranteed delivery times, we can now offer flexible responses with our stock items. The Importance of Procurement Design The manufacturing of probe pins often requires rare materials or materials with long lead times, making it crucial to implement a hybrid procurement design that combines "manufactured products" and "commercial stock items." This strategy will be vital for preventing disruptions in our customers' production lines in the future.
