Brass
Brass has been used for many years because of its unique formability and machining properties. Brass is therefore used for a multitude of applications, including sanitary fittings, pumps, fittings and couplings, technical fittings, lamp parts, and electricity and energy supply components. Thanks to its excellent properties and many possible combinations, brass is constantly used in exciting new challenging applications. The following brass alloys are frequently used by Müller Gas Equipment A/S because of their exceptional hot stamping properties.

Aluminium
Aluminium is renowned for its many excellent properties, particularly its lightness. Many people are unaware that aluminium can be hot stamped, providing considerable savings without compromising the beneficial properties of the material. The desired mechanical properties of aluminium are also retained as the material remains completely homogeneous throughout the hot stamping process.

Aluminium Bronze
Aluminum bronze is a versatile material in engineering and marine contexts. It is known for its high tensile and fatigue strength with high ductility (up to 400°C). Additionally, it exhibits very good atmospheric corrosion resistance. This material combines the strength of copper with the protective properties of aluminum oxide.
