Aluminum bronze contains copper, and about 6 to 12% of aluminum. It sometimes contains other metals such as iron, manganese, silicon and nickel. Aluminum bronze is a strong alloy. Because of its resistance to corrosion, especially to sea water, it is used in marine devices as well as oil, petrochemical supplies.

Phosphorous bronze, also known as “tin bronze” contains up to 11% of tin, and up to 0.35% of phosphorous, as well as copper. Phosphorous increases the bronze’s resistance. This alloy is known to be durable. Phosphor bronze is commonly used to make anti-corrosion equipment and to make some electrical devices such as washing machines, as well as tubes and musical instruments.

Silicon bronze, sometimes called “Red Silicon Bronze”, contains up to 6% of silicon and some copper and zinc. It can also consist of other alloys such as manganese, tin and iron. Silicon bronze is corrosion-resistant. It is commonly used to make parts for pumps and valves.

Manganese bronze is made up of 3% of manganese, in addition to copper, zinc, aluminum and iron, and it is impact resistant. It can also be distorted and may change its shape instead of being broken. Manganese bronze is highly resistant to corrosion in salt water, and therefore is often used in making boat propellers. Manganese bronze is also used in the manufacture of gears and nails.

Copper & Nickel Bronze
This type of bronze contains more nickel, ranging from 2% to 30% and also more copper. Like other types of bronze, it is durable and resistant to corrosion, especially in salt water. It also has high thermal stability. Copper bronze is used to make electronic parts, marine equipment, and ships.
