摘要

The metal part (10) comprises a body (12) made of aluminum and brazed under an action of heat at a brazing temperature. The body comprises an offsite surface (14) that is not brazed, and a thermal absorbent coating (16) of dark color intended to absorb heat at the time of brazing and to facilitate brazing of the part. The absorbent coating is: black color; an anodization coating; and resistant to the brazing temperature. The absorbent coating has a layer thickness of 1-50 mu m. The metal part comprises a shaped section comprising the absorbent coating on an external surface of the section. An independent claim is included for a method for manufacturing a metal part.
