90W-Ni-Fe Tungsten Dart Rod Blank

This product line offers two mainstream material grades: 90W-Ni-Fe, with a density of 16.85–17.25 g/cm³, and 95W-Ni-Fe, with a density of 17.75–18.35 g/cm³, covering the production requirements of both entry-level and high-end professional darts.

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 can reach a higher weight in a smaller volume, enabling a slimmer dart barrel design, better center-of-gravity concentration, and more stable throwing performance. Both sintered and polished surface finishes are available, and all dimensions can be fully customized in accordance with customer drawings and processing requirements. Completely lead-free and compliant with RoHS and REACH regulations, these billets are the preferred raw material for standard and custom professional darts.

Our 90W-Ni-Fe and 95W-Ni-Fe tungsten dart rod blanks adopt an optimized tungsten-nickel-iron ratio and one-step high-temperature sintering molding, delivering stable physical properties and excellent cutting performance that perfectly meet the requirements for high-precision turning, grooving, knurling and surface finishing of dart barrels.

• Full Market Coverage via Graded Selection: 90W-Ni-Fe delivers balanced density and cost performance for mid-range dart production, while 95W-Ni-Fe offers ultra-high density ideal for slim, high-weight professional tournament darts, covering the positioning demands of all market segments.

• Ultra-Stable Density andWeight Consistency: The uniform internal structure is completely free of pores and segregation, ensuring consistent single-piece weight and batch-to-batch stability, which effectively avoids weight deviation and unbalanced throwing of finished darts.

• Excellent Machinability Tailored for Dart Processing: The moderatehardness and good toughness support high-speed turning, precision grooving, knurling and thread processing without chipping, cracking or tool sticking, greatly improving the yield of finished darts

• High-Precision Customization Capability: We provide full-size customization services, including customized diameter, length, tolerance and special-shaped blank dimensions. All custom sizes follow the GB/T 1804 precision tolerance standard to match various dart processing fixtures.

• Dual Optional Surface Conditions: The surface of as-sintered blanks reserves sufficient machining allowance for complete processing, while polished smooth surfaces are available for semi-finished dart products that require less secondary processing.

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

• Eco-Friendly with Global Certifications: The 100% lead-free and non-toxic formula is fully compliant with international environmental standards, making it suitable for global sports equipment export and entry into high-standard mar

• Professional Dart BalancingPerformance: The high specific gravity enables a concentrated center-of-gravity design, effectively improving the stability, straightness and anti-deflection performance of dart throwing, making it ideal for professional competition-grade darts.

• High Batch Consistency: Standardized powder metallurgy production ensures consistentdensity, hardness and mechanical properties across all batches, guaranteeing uniform quality for mass-produced dart products.

• Flexible Secondary Processing: With reservedmachining allowance, it supports a variety of personalized processing methods including knurling, grooving, threading, surface sandblasting, polishing and pattern engraving, fully meeting customized dart barrel design requirements for amateur, professional and tournament-grade products.

• High-quality printed surrounding designs protect your walls while showcasing your personal style, and fully customized designs are available.
