Premium Direct Chill (DC) Cast Aluminum Billet

Fully Homogenized Extrusion Billets Made in Vietnam with C/O & Anti-Dumping Tariff Protection

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.

2. Business Benefits & Value Proposition (FAB Framework)

A. 100% Homogenized Structure

Feature: Advanced thermal homogenization dissolves segregation phases and transforms coarse β-AlFeSi into fine, spherical α-AlFeSi.
Advantage: Lowers breakout pressure in extrusion presses and enables higher ram extrusion speeds (+15% – 25%).
Benefit: Significantly increases daily profile output, reduces extrusion die wear, and lowers unit production costs for extruders.

B. Certified Vietnam Origin

Feature: Full C/O documentation (Form EUR.1, Form CPTPP, Form E, Form A/B) issued directly by Vietnam trade authorities.
Advantage: Allows buyers in the US, EU, Canada, and Australia to source high-grade billets while remaining compliant with international trade laws.
Benefit: Mitigates punitive anti-dumping tariff exposure (saving up to 30% – 80% in duty penalties) and ensures uninterrupted customs clearance.

C. 100% Ultrasonic Testing & Ceramic Degassing

Feature: Inline liquid metal filtration coupled with 100% non-destructive ultrasonic flaw inspection per billet.
Advantage: Guarantees zero internal slag inclusions, pinholes, or center-burst micro-cracks before dispatch.
Benefit: Prevents catastrophic die breakage during high-pressure extrusion, minimizes profile surface streaks, and drops scrap rates below 1%.

3. Quality Assurance, Packaging & Export Logistics

Strict Metallurgical Quality Control

  • OES Chemical Analysis: Dual Optical Emission Spectrometry testing per cast heat before pouring.
  • Microstructure & Grain Size Testing: Optical microscopy analysis to verify grain refinement and 100% homogenization phase transformation.
  • Non-Destructive Testing (NDT): Ultrasonic defect inspection to Class A/B standards.
  • Independent Inspection: Pre-shipment quality, length, weight, and chemical verification available via SGS, Bureau Veritas, or Intertek.

Export Packaging & Delivery Terms

  • Packaging: Steel-strapped export bundles with plastic end-cap protection or heat-treated wooden saddles. Moisture-proof protective film wrapping applied for long-haul maritime shipping.
  • Identification: Each bundle carries a weatherproof thermal barcoded label detailing Alloy, Heat Number, Billet Diameter, Length, and Net/Gross Weight for 100% traceability.
  • Incoterms: FOB Vietnam Ports (Cat Lai, Hai Phong, Cai Mep), CFR, CIF, DDP to destination port.
  • Supply Capacity: High-capacity production lines supporting contract-based annual volume supply and flexible spot order fulfillments (MTS/MTO).
