90W-Ni-Fe / 95W-Ni-Fe Tungsten Dart Rod Blank | Custom Tungsten Alloy Billet

Zhuzhou Jiuding Metal Technology Co., Ltd. 90W-Ni-Fe & 95W-Ni-Fe Tungsten Dart Rod Blanks are high-density tungsten heavy alloy billets specially produced for professional dart manufacturing and precision sports equipment processing. Manufactured by mature powder metallurgy liquid-phase sintering and precision rod forming technology, these dart rod blanks strictly comply with Mil-T-21014 US military standard, ASTM B777-99 / ASTM B777-15 (R2020), Chinese GB national quality standards and GB/T 1804-2000 dimensional tolerance specification. Available in two mainstream grades: 90W-Ni-Fe (density 16.85–17.25 g/cm³) and 95W-Ni-Fe (density 17.75–18.35 g/cm³), the series covers entry-level and high-end professional dart production requirements.

Tungsten dart rod blanks feature ultra-high density, uniform microstructure, stable hardness and excellent machinability. Compared with brass, steel and low-density alloy dart materials, tungsten nickel iron blanks achieve higher weight in smaller volume, enabling slimmer dart barrel design, better center-of-gravity concentration and more stable throwing performance. Both Sintered and Polished surface states are available, and all dimensions can be fully customized according to customer drawings and processing needs. Completely lead-free, RoHS and REACH compliant, these blanks are the preferred raw materials for standard and custom professional darts.

Core Product Advantages of Tungsten Dart Rod Blanks

90W-Ni-Fe and 95W-Ni-Fe tungsten dart rod blanks adopt optimized tungsten-nickel-iron ratio and one-time high-temperature sintering forming. With stable physical properties and excellent cutting performance, they perfectly meet high-precision turning, grooving, knurling and surface finishing for dart barrels:

• Grade Selection for Full Market Coverage: 90W-Ni-Fe offers balanced density and cost performance for mid-range dart production; 95W-Ni-Fe provides ultra-high density for slim, high-weight professional tournament darts, covering all market positioning demands.

• Ultra-Stable Density & Weight Consistency: Uniform internal structure without pores or segregation, ensuring consistent single-piece weight and batch stability. Effectively avoids weight deviation and unbalanced throwing of finished darts.

• Excellent Machinability for Dart Processing: Moderate hardness and good toughness support high-speed turning, precision grooving, knurling and thread processing without chipping, cracking or tool sticking, greatly improving finished dart yield.

• High Precision Customization Ability: Full-size customizable service, including custom diameter, length, tolerance and special-shaped blank size. All custom sizes follow GB/T 1804 precision tolerance standards to match various dart processing fixtures.

• Dual Optional Surface Status: Sintered blank surface reserves sufficient machining allowance for full processing; Polished smooth surface is available for semi-finished dart products requiring less secondary processing.

• Superior Wear & Deformation Resistance: High structural rigidity ensures no deformation during high-speed machining and long-term use, maintaining stable barrel roundness and surface flatness.

• Eco-Friendly & Globally Certified: 100% lead-free and non-toxic formula, fully compliant with international environmental standards, suitable for global sports equipment export and high-standard market access.

Product Performance Features

• Professional Dart Balance Performance: High specific gravity realizes concentrated gravity design, effectively improving dart throwing stability, straightness and anti-deflection ability, ideal for professional competition-grade darts.

• High Batch Consistency: Standardized powder metallurgy production ensures identical density, hardness and mechanical properties for each batch, guaranteeing unified quality of mass-produced dart products.

• Flexible Secondary Processing: Reserved machining allowance supports various personalized processing such as knurling, grooving, threading, surface sandblasting, polishing and pattern carving, fully meeting customized dart barrel designs for amateur, professional and tournament-grade products.
