Explanation: Even though the strength of bronze increases with increasing tin content, they are kept below 12% as they tend to become brittle. Bronzes have better corrosion resistance than brasses.

Explanation: Bell bronze is a hard and brittle alloy with a resonance ability. It consists of 78% copper and 22% tin. It is typically used for making bells.

Explanation: Leaded bronze has increased strength, due to which it can carry high leads, and has the ability to work at higher speeds. It is used as a bearing alloy. It consists of 75% copper, 5% tin, 18% lead, and 2% nickel.

Explanation: Aluminum bronzes are used for making gears, propellers, cams, and other parts which require good strength and hardness. Therefore, iron is added to aluminum to achieve this result. The composition of iron is 3.5%, with the remaining being 89% copper, 7% aluminum, and 0.35% tin.

Explanation: Silicon bronze contains 95% copper, 3% silicon, 1% manganese, and 1% iron. Although it does not contain tin, it is still classified as a bronze alloy due to its color. Silicon is added to increase strength and improve corrosion resistance.

Explanation: Coinage bronzes have good strength and corrosion resistance. This makes them ideal for making copper coins. It consists of 95.5% copper, 3% tin, and 1.5% zinc.

Explanation: Gunmetal is an alloy of copper containing tin and zinc. They are used to make pumps, valves, marine castings etc.

Explanation: Gunmetal, when added with zinc, improves fluidity during casting and also acts as a deoxidizer. Since zinc is cheaper than tin, it also results in a decrease in overall cost. Increased machinability and castability are due to the addition of lead.

Explanation: Admiralty gun metals have high corrosion resistance and casting properties. They are used for making pumps, valves, statuary and other castings. They contain 88% Cu, 10% Sn, 2% Zn, and 2% Ni. Leaded gunmetal is used for making bearings, marine castings, hydraulic valves etc.

Explanation: Cupronickels are alloys of nickel and copper. They are ductile, malleable, and can be hot-worked or cold-worked. They have better corrosion resistance than most copper alloys in seawater.

Explanation: Monel metal is a type of cupronickel containing 29% Cu, 68% Ni, 1.25% Fe, and 1.25% Mn. It has excellent corrosion resistance and good mechanical properties. They are used for making propellers, condenser tubes, pump fittings etc.

Explanation: K monel is a type of cupronickel alloy. It is a heat treated alloy and has good mechanical properties. It is used for making motorboat propeller shafts.

Explanation: German silver is an alloy of copper, containing copper, nickel, and zinc. It is also known as nickel silver. They are used for manufacturing cutlery and decorative items.
