Aluminum brass alloy is a type of brass alloy that contains aluminum as one of its main alloying elements, along with copper and zinc. The aluminum content can vary, typically ranging from 5% to 12%, with copper usually being the majority component.

Aluminum brass alloys have good strength, corrosion resistance, and thermal conductivity, making them useful in a variety of applications. They are often used in marine environments due to their resistance to seawater corrosion, as well as in heat exchangers, condensers, and other equipment that require good thermal conductivity.

The aluminum content in aluminum brass alloys can affect their properties. Higher aluminum content can increase the alloy’s strength and corrosion resistance, but may reduce its ductility and ease of fabrication. Conversely, lower aluminum content can improve the alloy’s ductility and ease of fabrication, but may reduce its strength and corrosion resistance. The choice of aluminum brass alloy depends on the specific application requirements.

UNS C68700

UNS C68700 is a copper-zinc alloy that is also known as aluminum brass. It is a wrought alloy that contains 76-79% copper, 20-23% zinc, and small amounts of aluminum and other elements. The aluminum content in C68700 is usually less than 1%, which gives it good resistance to corrosion in seawater and other corrosive environments.

UNS C68700 has excellent thermal conductivity and is often used in heat exchangers and condenser tubes for seawater applications, as well as in other marine and industrial applications that require good corrosion resistance and thermal conductivity. It is also used in the manufacture of ammunition cartridges due to its high machinability and good mechanical properties.

UNS C68700 is a readily weldable and workable alloy, and it can be fabricated using a variety of methods, including brazing, soldering, and welding. It has good strength, ductility, and toughness, and it can be easily formed into different shapes and sizes.
