![]() Douglas and others,
Hello all, onlinemetals.com offers Aluminum Bronze, alloy C95400, in 3/8"x2" and 1.5". The total cost for all of the bronze I need (12ft of 2", 6ft of 1.5") would be about $300. I have seen people say that aluminum nickle bronze and silicon bronze are good choices for use as chainplates. However, I'm not sure about "aluminum bronze". It's specifications are thus: Aluminum Bronze, C954 Minimum Properties Ultimate Tensile Strength, psi 85,000 Yield Strength, psi 32,000 Elongation in 2" 12% Brinell Hardness 170 Chemistry Copper (Cu) 83.0% min Iron (Fe) 3.0 - 5.0% Aluminum (Al) 10.0 - 11.5% As opposed to silicon bronze: Silicon Bronze, C655 Minimum Properties Ultimate Tensile Strength, psi 85,000 Yield Strength, psi 55,000 Elongation in 2" 20% Rockwell Hardness B90 Chemistry Copper (Cu) 97.0% min Iron (Fe) 0.8% max Manganese (Mn) 1.5% max Nickel (Ni) 0.6% max Lead (Pb) 0.5% max Silicon (Si) 2.8 - 3.8% Zinc (Zn) 1.5% max Does anyone have experience using aluminum bronze; I want to make sure it is a strong enough metal. I'm not sure if "32,000 psi" for yield strength is enough compared to silicon bronze's "55,000 psi". I have found sources for aluminum nickle and silicon bronze sheet, but the total cost is near or above $1000, and I'd still have to cut it, so if this "aluminum bronze" is acceptable, it would be nice! Thank you for your time! Aaron
