JIS C1441 compliant product! A copper alloy bar with excellent strength, heat resistance, and good workability.
"SNDC" is a heat-resistant copper strip that has been solid-solution strengthened by adding 0.15% Sn to copper, improving strength, heat resistance, and stress relaxation resistance. The effect of Sn reduces the anisotropy of the rolled structure, resulting in good press workability. Conventional brass materials no longer meet the demands for improved reliability such as high performance and high corrosion resistance of components, making it ideal for cases considering a switch to copper-based materials. Additionally, it is suitable for cases where the currently used copper-based materials are of excessive quality, prompting a consideration for more economical materials. 【Features】 ○ Complies with JIS C1441 standards ○ Excellent strength and heat resistance, with good workability ○ Superior corrosion resistance against stress corrosion cracking, with good plating and soldering properties ○ High conductivity, capable of keeping the temperature rise during current flow low For more details, please contact us or download the catalog.
