Copper alloy tube Hardiall®

for aeronautics

Hardiall® range of spinodal alloys are wrought copper nickel tin materials : -Very high strength, heavy duty and high load capacity CuNi15Sn8 (C72900) version called Hardiall® -High strength, heavy duty and high load capacity CuNi9Sn6 (C72700) version called Hardiall Eco® Both are designed for high performance applications where excellent high friction wear resistance, galling and toughness requirements are needed. They are easily machined into complex components whilst being environmentally friendly, being both lead free and beryllium free, and are easily recyclable. Lebronze alloys being fully integrated for all processes mitigates supply chain risks offering semi-finished products but also is able to propose ready-to-use finished products. Standards: Hardiall® wrought CuNi15Sn8: UNS C72900; ASTM B505. CW355H EN 12163 tempers Y760 R1100 R1130 Hardiall® CuNi15Sn8 complies with and exceeds the aerospace standards (AMS 4596, 4597, 4598, UT AMS 2154 class B…) as well as Oil & Gas customers specifications including NACE MR0175 corrosion and UT API-6A paragraph 7.4.2.3.17. controls. Hardiall® is the ideal substitute to Beryllium Copper CuBe2 C172000 CW101C as per EN 12163: Hardiall® CuNi15Sn8 reaches similar mechanical properties as well as superior surface properties and workability. Hardiall® is a direct equivalent to Toughmet® 3 and is an ideal proven track record solution. Extensive testing ensures that Hardiall® is in full compliance with the relevant specifications: in that regard, using Hardiall® can help high-end industries mitigate their supply chain risks.
