• Forged + drawn grain control — Combined forging and drawing process with precise heat treatment optimizes grain structure for high strength, creep resistance, and dimensional stability. No shortcuts on microstructural quality.
• Full heat-to-bar traceability — Every bar traceable to original heat number with EN 10204 3.1 MTC included as standard. Multi-point quality chain from incoming billet through finished bar inspection under ISO9001.
• 8.0–200mm diameter range — From precision small-diameter bars for fasteners and machining blanks to large forged bars for shafts and structural components. One supplier for your full size range.
• Integrated production under one roof — Forging, hot rolling, drawing, heat treatment, straightening, and testing all in-house. No quality gaps from outsourced processing steps.
• Age-hardened grades ready to machine — Inconel 718 and X750 available in solution-annealed or fully age-hardened (precipitation-hardened) condition. Specify your required heat treatment state — we deliver ready for your machining operation.
• Application-level support — Our metallurgical team reviews your service conditions before recommending grade, heat treatment state, and bar diameter. Not just material supply — engineering partnership.

Changzhou DLX Alloy Co., Ltd. was founded in 2002 with a single focus: nickel-based specialty alloys. We are not a general metal distributor — every piece of equipment, process parameter, and quality checkpoint is designed around nickel alloy manufacturing.

• 12,000 m² dedicated facility with integrated melting, forging, rolling, drawing, heat treatment, and NDT testing capabilities — bars are produced under one roof, from billet to finished product
• 1,200-ton annual capacity, with automated rolling and drawing lines that improve throughput by ~25% over conventional equipment
• Full size range: 8.0–200mm diameter — from small-diameter precision bars for machining to large forged bars for heavy-duty shafts and structural components
• Five product forms — bar, strip, tube, plate, and wire — enabling integrated supply for customers sourcing multiple product types
• ISO9001 quality management with multi-point traceability; SGS-accredited with BV and TÜV third-party inspection available

Note: Inconel 718 and X750 values are for age-hardened condition. Solution-annealed and other heat treatment conditions available on request.

Every Inconel bar order from DLX undergoes:

Third-party inspection by SGS, BV, or TÜV available upon request. All shipments fully documented and traceable to heat number.

Yes. DLX manufactures to your specified diameter and tolerance class (h8–k12). For diameters between standard mill sizes, we can produce via drawing or peel turning to meet your exact requirement.

Yes. Third-party NDT and material verification by SGS, BV, or TÜV can be arranged. Ultrasonic testing per ASTM A388 / AMS 2301 is available as standard or to your specific acceptance criteria.

MOQ is negotiated per grade, diameter, and specification. We support trial quantities for first-time buyers to validate quality and machinability before committing to production volumes.

Yes. Both solution-annealed (ready for your in-house heat treatment) and fully age-hardened conditions are available. Specify your target hardness range or mechanical property requirements — we supply to AMS 5662 / AMS 5663 specifications.

Every shipment includes EN 10204 3.1 MTC with full chemical composition and mechanical properties, UT test reports (if specified), dimensional inspection report, certificate of conformance, and packing list. All documentation traceable to original heat number.
