A high-strength copper alloy that combines high strength and high toughness, with excellent wear resistance and corrosion resistance.
"FH-5" is our original high-strength copper alloy that is far superior to JIS standard CAC303 (HBsC3) and ASTM-B147-8C SAE430B. It has excellent wear resistance that does not cause wear on the counterpart material even in cases of insufficient lubrication. It can be used for applications such as drawing male threads, slippers, liners, and wear plates for bridges, where high tensile strength, high compressive strength, and high wear resistance are required. 【Chemical Composition】 ■Cu: 60.0–68.0 ■Zn: remainder ■Mn: 3.0–5.0 ■Al: 3.0–7.5 ■Fe: 2.5–4.5 ■Sn: <0.25 ■Others: <0.25 *For more details, please download the PDF or feel free to contact us.
