Premium Direct Chill (DC) Cast Aluminum Billet
Efreso supplies high-precision Direct Chill (DC) Cast & Fully Homogenized Aluminum Billets engineered for high-speed, defect-free extrusion lines. Manufactured in Vietnam to strict international standards (ASTM B221, EN 573-3, JIS H4040, GB/T 3190), our billets feature ultra-fine grain structures, low gas porosity, and zero internal cracking.
With 100% Verified Made-in-Vietnam Certificates of Origin (C/O) (Form EUR.1, Form CPTPP, Form E, Form A/B), Efreso helps international aluminum extruders and tier-1 industrial manufacturers bypass high anti-dumping tariffs, optimize landed costs, and secure a resilient, sustainable raw material supply chain.
