Tōkai Gokin's "TS25" is a specialized carbide alloy that combines "low bonding phase amount," "coarse grain WC," and "anti-seizing properties" necessary to suppress adhesive wear of tools in the processing of SPCC. With high resistance to adhesive wear, it is suitable as a tool material for processing SPCC materials and others. Compared to materials of the same hardness range that we handle, it achieves approximately a 40% reduction in wear, contributing to improved tool life and reduced maintenance costs. Additionally, it has excellent corrosion resistance, suppressing the ionization of the bonding phase. It can also prevent skin roughness (seizing damage) and quality deterioration associated with corrosion on the tool surface. 【Features】 ■ Composition design suitable for processing SPCC ■ Contributes to the long life of tools with excellent adhesive wear resistance ■ Among our products, it has top-class corrosion resistance *For more details, please refer to the PDF document or feel free to contact us.

"AGS1" is an ultra-fine particle cemented carbide with high hardness and high strength, utilizing our company's powder manufacturing/sintering technology. It achieves high hardness among Tokaroi materials and demonstrates excellent wear resistance. Compared to other companies' ultra-fine particle cemented carbides, it balances high hardness and high strength. For applications requiring advanced edge retention, such as cutting metal foils and films, we have optimized the composition of ultra-fine particles to achieve superior "sharp edges" compared to conventional types. **Features of ultra-fine particle cemented carbide 'AGS1':** - High hardness, high strength, wear resistance - Corrosion resistance - Coating adhesion - Edge retention, surface roughness *For more details, please refer to the PDF document or feel free to contact us.*
