We accept age-hardening treatment of beryllium copper (C1720).
NGK manufactured beryllium copper (C1720)
To fully realize the true value of beryllium copper, aging heat treatment is necessary. The products purchased from us will undergo heat treatment.
Beryllium copper is an alloy that adds a small amount of beryllium to copper. It has the highest strength among copper alloys, possesses high springiness, and features non-magnetic properties, spark-free operation, and high corrosion resistance. Furthermore, it has properties suitable for metal processing, molding, and machining, and is widely used in mechanical parts, electrical and electronic component contacts and switches, electrodes requiring strength and conductivity, heat-resistant wires, brushes, sockets, and probe pins. Beryllium copper undergoes precipitation hardening, where beryllium precipitates within the structure, resulting in tensile strength and hardness values that are among the highest for copper alloys (up to 1500 N/mm² for C1720). This process is known as aging treatment (heat treatment); however, after aging treatment, there can be cases where bending processing leads to cracking or where machining resistance is high, making it difficult to process effectively. Since its machinability is not as good compared to brass, it is often the case that the material is partially processed before heat treatment for finishing, or that aging treatment is performed after machining. There are recommended settings for heat treatment that are somewhat fixed. Our company collaborates with businesses that have heat treatment furnaces to provide aging treatment for materials purchased from us, such as those from NGK (Nippon Gas Co., Ltd.).

Company information
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.
