Aluminum Bronze C95400 Unwrought Ingots
Aluminum bronze C95400 unwrought ingots, containing 10-11.5% aluminum, 4% iron, and 3.5-5% tin. Although aluminum is present in higher proportion than tin, the alloy is classified as a copper-tin base alloy because tin predominates over each of the other elements individually, per the subheading note. These ingots are used for heavy-duty gears and marine propellers.
High-Leaded Tin Bronze C93800 Ingots
High-leaded tin bronze C93800 ingots with 10% tin and 20% lead, used for screw machine products requiring exceptional machinability. Despite the high lead content, tin predominates over lead and other elements, maintaining classification as a copper-tin base alloy under subheading note (b).
Leaded Tin Bronze C93200 Unwrought Bars
Leaded tin bronze C93200 unwrought bars, also known as SAE 660, containing 6-8% tin and 6-8% lead, used for bearings and bushings. The tin content ensures classification as a copper-tin base alloy, as tin predominates over lead and other elements, per the subheading note.
Manganese Bronze C86500 Unwrought Form
Manganese bronze C86500 unwrought castings with 4% tin, 39% zinc, and 3% manganese, used for high-tensile marine castings and gears. Although zinc is present in higher proportion, the alloy is classified as copper-tin base because tin predominates over each other element individually, and the zinc content exceeds 10% but the tin content is 3% or more, allowing this exception under the subheading note.
Naval Bronze C46400 Unwrought Plates
Naval bronze C46400 unwrought plates with 39-42% zinc and 5% tin, used for traditional propeller and valve applications. The tin content of 5% (≥3%) allows the zinc content to exceed tin, but the alloy remains a copper-tin base alloy because tin predominates over each other element individually, per the subheading note.
Silicon Bronze C65500 Unwrought Rods
Silicon bronze C65500 unwrought rods containing 3% silicon and 4.8% tin, used for marine hardware and weld rods. The tin content predominates over silicon, classifying the alloy as a copper-tin base alloy under subheading note (b). The rods are cast sections not mechanically worked.
