Charpy Metallurgical services established to support Aluminium extrusion industry in the field of investigation of metallurgical issues faced by extruders. Supporting to establish billet quality criterion for various applications.
Charpy metallurgical services develop billet metallurgical requirements for innovative, value added aluminium products for a broad scope of markets and applications, including aerospace, automotive and packaging.
Billet quality is the one of the main criteria to improve the productivity and rejection rate in extrusion production lines. The main metallurgical criteria of extrusion billets are:
Inverse segregation zone
Intermetallic particles size and distribution
Micro Porosity density and size
Inclusions in billet ( size and type)
Dendrite Arm Spacing
