伸和商事 List of Products and Services

We stock products such as phosphor bronze, nickel silver, and beryllium copper as standard lengths. However, we understand that there are often requests like the following: ■ I would like to have thick materials cut before processing. ■ I need a small quantity, so I would like to purchase in small lots. ■ Due to transportation weight and processing machine specifications, I would like them cut in half before delivery. At Shinwa Shoji, we provide the necessary items in the required quantities with the fastest delivery times. We ship long products (standard round bars of 2000mm to 2500mm) and standard plates, whether in small quantities or over several hundred kilograms, to locations nationwide. If you have any issues, such as needing prototypes or urgent arrangements for copper alloys, please feel free to contact us.

"Aluminum bronze" is an alloy made by adding tin and a small amount of phosphorus to copper. "C5191" is an alloy with 5.5% to 7% tin added to copper, while "C5212" is a material that has increased hardness by adding even more tin. Since C5191 and C5212 do not contain lead, they are difficult-to-machine materials in precision cutting processes, but they are highly ductile and have good bending and plating properties. 【Features】 ■ Mechanical strength ■ High elasticity ■ Corrosion resistance ■ Fatigue resistance ■ Wear resistance *For more details, please download the PDF or feel free to contact us.
