Excellent Aluminum Bronze Alloy High Hardness¹

Product Description The product is a patented hard grade aluminium bronze. Its exceptional hardness makes it a unique material. However, this extreme hardness means fragility and machinability difficulties. This alloy has very limited uses and machinability, but it gives exceptional results.Mechanical and physical UnitsNominal valueTensile strength R mMPa 793Specified non-proportional extension strength R p0.5MPa 407Elongation after breaking A%10Brinell hardnessHBW 10/3000228Rockwell hardnessHRB98Reduction of area Z%8Compressive strength R mcMpa1069Specified non-proportional compressive strength R pc0.1Mpa441Compression ratio limit R pcMpa338Shear strength R cmMpa427Elastic modulus EGpa110Charpy shock absorption energy AKJ11Izod impact absorption power AKJ16.3Fatigue strength (100'000'000 times) σNMpa248Density ρg / cm37.45Coefficient of linear expansion α10-6 / K16.2Thermal conductivity λW / m · K59Conductivity γm /  Ω· mm27.5Conductivity% I.A.C.S.13Specific heat capacity cpJ / g · K0.42APPLICATIONS Stainless steel drawing dies, forming rolls under great stresses and extreme pressures are the most typical applications for this alloy.Chemical compositionAl:10.5%   Fe:3.5%  Other:Up to 0.5%    The rest is copper
