EUTungsten Heavy Alloy Supply for UK Industrial and Engineering Applications
Tailored Material Engineering for the UK Manufacturing Landscape
Across the United Kingdom—from the aerospace clusters in the South West and Midlands to North Sea offshore hubs in Aberdeen and advanced nuclear medical institutes across England—engineering projects demand non-negotiable material integrity. With post-Brexit supply chain optimization, UK buyers prioritize high-reliability source factories that can guarantee UK REACH compliance, BS EN ISO quality standards, and predictable lead times.
UK REACH & Safety Compliance
Our dense tungsten heavy alloys act as an eco-friendly, non-toxic alternative to hazardous lead (Pb), aligning completely with UK environmental regulations and RoHS/REACH sustainability standards.
Aerospace & Motorsport Precision
Serving Tier-1 aerospace suppliers and motorsport engineering teams with precise mass-balancing blocks, crankshaft weights, and flight control balancing rods with tight CNC tolerances down to ±0.005mm.
Reliable Factory Direct Logistics
From rapid sample prototypes shipped via air freight (DAP/DDP) to Birmingham, Heathrow, or Manchester to containerized batch deliveries, we guarantee complete traceability and Mill Test Certificates (EN 10204 3.1).
Standard Tungsten Heavy Alloy Technical Specifications
Jiuding Metal manufactures high-density tungsten alloys strictly in accordance with ASTM B777, AMS-T-21014, and ISO standards. Our powder metallurgy and precision sintering processes ensure maximum density consistency and superior mechanical properties.
| ASTM B777 Class | Nominal Composition | Density (g/cm³) | Hardness (HRC) | Tensile Strength (MPa) | Elongation (%) | Magnetic Property |
|---|---|---|---|---|---|---|
| Class 1 | 90% W-Ni-Fe | 17.00 ± 0.15 | 24 - 30 | ≥ 750 | ≥ 10 | Slightly Magnetic |
| Class 1 (Non-Mag) | 90% W-Ni-Cu | 17.00 ± 0.15 | 23 - 28 | ≥ 650 | ≥ 8 | Non-Magnetic |
| Class 2 | 92.5% W-Ni-Fe | 17.50 ± 0.15 | 25 - 32 | ≥ 800 | ≥ 8 | Slightly Magnetic |
| Class 3 | 95% W-Ni-Fe | 18.00 ± 0.15 | 27 - 34 | ≥ 850 | ≥ 7 | Slightly Magnetic |
| Class 4 | 97% W-Ni-Fe | 18.50 ± 0.15 | 28 - 36 | ≥ 850 | ≥ 5 | Slightly Magnetic |
Note: Customized formulations including high-temperature resistant tungsten alloys, copper-tungsten EDM grades (CuW70, CuW80), and swaged high-strength rod blanks (>1200 MPa tensile strength) are available on demand with comprehensive mechanical testing reports.

Frequently Asked Questions by UK Engineering Teams
1. How does Tungsten Heavy Alloy compare to Lead for radiation shielding in the UK?
Tungsten alloys provide 40-50% greater radiation attenuation density than lead, requiring substantially less thickness to achieve equal protection. Additionally, tungsten is non-toxic, structurally rigid, easily machinable, and fully compliant with UK environmental workplace health standards.
2. What is the difference between W-Ni-Fe and W-Ni-Cu alloys?
W-Ni-Fe (Tungsten-Nickel-Iron) exhibits higher tensile strength and elongation, making it ideal for structural counterweights, crankshafts, and general shielding. W-Ni-Cu (Tungsten-Nickel-Copper) is completely non-magnetic, making it essential for MRI environments, sensitive instrumentation, and electronic testing equipment.
3. What CAD formats do you accept for custom manufacturing quotes?
We accept 2D drawings (PDF, DWG, DXF) with clear tolerance callouts as well as 3D model files (STEP, IGES, XT). Our engineering department provides rapid DFM (Design for Manufacturability) analysis and quotes within 24 hours.
4. How are overseas shipments handled for UK destinations?
We partner with international freight handlers (DHL, FedEx, UPS, air & sea logistics) providing door-to-door (DAP or DDP) delivery across the UK. All consignments are packed with industrial wooden crates, moisture-proof barriers, and complete export compliance documentation.
