4047 aluminum alloy introduction

Standard: UNS A94047 AMS 4185 Place of Origin: USA

(Unified number system representation method for metal and alloy grades. The UNS system is composed of a letter and 5 digits.

For deformed aluminum alloys, the grades have the prefix "A9" plus AA standard 4 for cross composition, for example, AA mark

The digital grade of the UNS system is 4047, then the digital grade of the UNS system is A94047)
