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, tin predominates over each other individual element per subheading note (b), classifying this as a copper-tin base alloy. These ingots are used for heavy-duty gears and marine propellers.
