Manufacturing method for heat resistant aluminium alloy shaped products, heat resistant aluminium alloy shaped products, and forming apparatus for heat resistant aluminium alloy shaped products

摘要

A manufacturing method for heat resistant aluminium alloy shaped products forms a shaped product by performing hot extrusion of a material (billet) made of a heat resistant aluminium alloy. The hot extrusion is performed causing a temperature of the shaped product immediately after the hot extrusion to fall within a range between 350°C and below 550°C.
