Aluminum Hokotol vs MoldMAX Aluminum

Aluminum · grade comparison

Aluminum Hokotol and MoldMAX Aluminum are both aluminum grades, both mold quality al. Both yield at about 480 MPa — strength does not separate them. MoldMAX Aluminum is the more ductile: elongation 8% versus 6% for Hokotol, and Hokotol is harder (165 HB vs 150 HB). Hokotol conducts heat better (150 W/m·K vs 130 W/m·K).
