Tungsten Bars: Sourcing, Types, and Buyer's Guide for 2025


Tungsten bars are essential in industries requiring high-density, heat-resistant materials. Whether you're in aerospace, defense, or manufacturing, understanding how to source quality tungsten bars can save costs and improve efficiency. This guide covers key aspects like types, functions, and how to find trusted suppliers.


How to Find Reliable Tungsten Bars from China in 2025


China remains a top supplier of tungsten bars, but verifying suppliers is critical. Look for:

  • Certifications: ISO 9001, RoHS, or industry-specific standards.
  • Production Capacity: Ensure they meet bulk order demands.
  • Customer Reviews: Check Alibaba or industry forums for feedback.

For example, a Shenzhen-based supplier reduced lead times by 30% after adopting automated quality checks.


What Buyers Should Know Before Buying Tungsten Bars from China


Key considerations:

  • Pricing: Compare FOB vs. CIF quotes; hidden fees can add 10–15%.
  • Material Purity: 99.95% purity is standard for industrial use.
  • Shipping: Opt for suppliers with experience in hazardous material logistics.

Types of Tungsten Bars


Common variants include:

  • Sintered Tungsten Bars: High density (18.5 g/cm³), used in radiation shielding.
  • Forged Tungsten Bars: Superior strength for aerospace components.
  • Alloyed Bars: Mixed with nickel or iron for improved machinability.

Functions and Features of Tungsten Bars


Why choose tungsten?

  • Melting point: 3,422°C (highest of all metals).
  • Exceptional wear resistance—lasts 5× longer than steel in abrasive environments.
  • Non-toxic and recyclable, ideal for eco-conscious projects.

Scenarios of Tungsten Bars


Applications span:

  • Medical: Radiation collimators in radiotherapy machines.
  • Energy: Counterweights in wind turbine blades.
  • Defense: Armor-piercing projectiles.

How to Choose Tungsten Bars


Match the bar to your needs:

  • For high-temperature furnaces, prioritize purity (>99.9%).
  • For machining, alloyed bars reduce tool wear.
  • Request samples to test hardness (typically 200–300 HV).

Tungsten Bars Q & A


Q: What’s the average lead time for orders from China?
A: 4–6 weeks for standard sizes; custom orders may take 8+ weeks.

Q: Are there export restrictions?
A: Some countries regulate tungsten due to dual-use (military/civilian) applications—check local laws.

Q: How do I verify material quality?
A> Request third-party lab reports (e.g., SGS) for density and composition.

Q: Can tungsten bars be welded?
A: Yes, but specialized techniques like electron-beam welding are required.

Q: What’s the price range per kg?
A: $50–$120/kg, depending on purity and order volume.
