Special material G.AL® C210 DYNAMIC is an advancement of the almost universally applicable G.AL® C210R from alloy EN AW-5083 (AlMg4.5Mn0.7). The outstanding features of medium-strength aluminum plate G.AL® C210 DYNAMIC sawn on all sides – absolutely free of microporosity, isotropy, and extremely low-stress properties – are generated by special casting parameters, elaborate post-processing and special heat treatment.


Vacuum technology

The complete diffusion resistance due to the lack of microporosity of G.AL® C210 DYNAMIC and a very good outgassing behavior under thermal influences, which corresponds to that of stainless steel, makes G.AL® C210 DYNAMIC the perfect choice for all vacuum applications. The density (helium leak test) was tested up to a vacuum 10-11.


Diffusion resistance also plays a crucial role in pneumatics. Usually, low- and medium-strength, sometimes even high-strength rolled plates are used in this field. Conventional cast plates are not suitable for such applications due to the risk of microporosity. The absolute absence of pores makes G.AL® C210 DYNAMIC superior all other materials in this segment: rolled plates from a thickness of 2.25” upwards are also prone to porosity.

Medical technology

The operational reliability of pressure-loaded or media-carrying components is highly dependent on the nature of the materials used. Microporosity can lead to premature wear and leaks in the equipment. Non-porous G.AL® C210 DYNAMIC is therefore the first choice in these cases and is also suitable for applications in medical technology in accordance with EN 602-2004.

Laser technology, optical industry

The silicon outgassing and other outgassing, e.g. from coolants, dreaded in this industry due to microporosity can be avoided by using G.AL® C210 DYNAMIC thanks to the low, extremely compact and firmly embedded silicon content. The excellent dimensional stability of G.AL® C210 DYNAMIC also allows for degrees of machinability of >95%.

For applications in vacuum technology, diffusion resistance and outgassing are extremely important. The highly compact and non-porous structure of G.AL® C210 DYNAMIC ensures superior reliability needed in this field.
