Cast aluminum is a high-tension topic as long as it’s low-tension.

Cast-Blocks and -plates EN AW-5083 (Al Mg 4,5 Mn)

Our aluminum cast plates of alloy EN AW-5083 (AL Mg 4.5 Mn) are characterized by its low stress levels. All cast ingots are homogenized (annealed) and highly stress-relieved. AMCO manufactures the aluminum cast plates in various thicknesses and dimension on modern machines. By homogenizing the ingots an excellent microstructure can be achieved. Therefore, the product is particularly suitable for components with complex machining, especially for tool- and mold making industries as well as engineering

Our manufacturing process: for outstanding material properties of a truly miraculous product

You’ve got to get the base material right – that’s the only way we can deliver perfect quality. This is why we choose our suppliers based on the strictest criteria - and we check the supplied ingots precisely for hydrogen content and inclusions. Beyond this, AMCO sets great store by all of our business partners working with certified heat treating companies. Our hardness tests for our suppliers and materials mean we make sure that all of the ingots delivered are low tension and have outstanding micro-structures, excellent strength and machining properties. This is the only way they are perfectly suited to blanks according to your specifications and applications.
