Ishigaki Store reveals the techniques and challenges of copper processing.

The copper processing at Ishigaki Shoten is based on a deep understanding and technology of the unique properties of C1100 tough pitch copper. During processing, the material's flexibility, high density, and ductility present significant challenges. In particular, during press processing, the material's stickiness and the adhesion of the mold due to heat are critical issues, while in machining, managing the high thermal conductivity and burr generation is essential. Ishigaki Shoten overcomes these challenges to provide high-quality copper products. The difficulties of copper processing and the characteristics of C1100 Challenges in press processing and machining Techniques for cutting and lathe processing *For more details, please refer to the PDF materials or feel free to contact us.

basic information

Choosing the optimal material and size when selecting copper bars significantly impacts product performance, cost, and delivery time. Below is a guide on how to choose the material and basic dimensions of copper bars. Material: C1100: Has high electrical conductivity and is generally suitable for electrical applications. C1020: Combines excellent thermal conductivity and workability, making it suitable for specific applications. Size (Cross-sectional area: Height × Width): Width: 12mm, 15mm, 20mm, 25mm, 30mm, 40mm, 50mm, 75mm, 100mm, 150mm, 200mm Height: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 15mm, 20mm The cross-sectional area of the copper bar conforms to these basic dimensions, allowing for various combinations. When making a selection, consider the following points: Material cost: Choosing standard sizes can reduce costs. Delivery time: Selecting standard products can lead to quicker arrangements and shorter delivery times.
