Aluminium Billets / Logs / T‑Bars

Description

1. Product Overview
Our Aluminium Billets, Logs, and T‑Bars are high‑purity, homogenized semi‑finished cast products engineered for downstream extrusion and forming processes. Primary industrial applications include automotive structural components, building systems, and industrial machinery frames. The key value proposition is superior dimensional consistency and metallurgical stability, which directly reduces extrusion scrap rates by up to 12% and extends die life. Strategically, securing a reliable source of certified aluminium feed stock mitigates supply chain volatility and ensures compliance with global lightweighting and recycling mandates.

2. Key Specifications & Technical Characteristics

• Chemical Composition: EN AW‑6060, 6063, 6082, 7075; or custom alloys (1xxx–7xxx series) per customer spec; maximum Fe ≤0.20%, Si ≤0.10% for high‑grade 6xxx series

• Purity / Grade: Primary aluminium base ≥99.7% (P1020A equivalent) or recycled content P0610; homogenized and stress‑relieved

• Physical Characteristics: Cylindrical billet diameters 3″ to 16″; T‑Bar widths 50–300 mm; as‑cast or peeled surface; grain refinement ASTM E112 level 5 or finer; density 2.70 g/cm³

• Packaging: Steel‑strapped bundles on treated wooden skids; moisture‑shrink wrapped for ocean transport; optional edge protectors for T‑Bars

• Shelf Life: Indefinite under dry, covered storage (no chemical degradation; surface oxidation ≤0.01 mm per year)

3. Core Industrial Applications

• Primary industries: Automotive (EV battery trays, crash management systems); building & construction (curtain walls, window frames); industrial automation (linear rails, pneumatic cylinders); consumer electronics enclosures.

• Operational use cases: Hot extrusion into complex profiles; cold drawing into precision tubes; CNC machining of T‑Bars into jigs and machine bases.

• Performance advantages: Homogenization eliminates micro‑segregation, reducing surface defects (pickup, tearing) by 40% vs. non‑homogenized stock. Tight ovality tolerance (±0.5 mm) enables faster extrusion speeds (up to 25 m/min). For T‑Bars, the as‑extruded corner radii allow direct machining without pre‑milling, cutting lead times by 20%.

• Cost advantage: Lower die wear and fewer stoppages reduce total cost per extruded kilogram by 8–15% compared to standard market billets.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified; each lot certified with 100% spark emission spectrometry and ultrasonic flaw detection; batch traceability to cast house.

• Supply reliability: Dual‑source smelting (Gulf and Southeast Asia) with 50,000 MT buffer stock at Rotterdam and Busan hubs.

• Logistics capability: 24‑hour load readiness; vessel loading up to 25,000 MT per shipment; LCL/FCL options.

• Price competitiveness: Long‑term contracts indexed to LME + fixed premium with downside floor protection.

• Sustainability: Up to 75% post‑consumer scrap content available (Scandia‑certified); carbon footprint <2.5 kg CO₂e per kg of billet.

• Technical support: Full extrusion simulation (HyperXtrude) to recommend preheat and quench parameters; on‑site die‑matching service for complex T‑Bar profiles.

5. Commercial & Supply Information
