Product Description

We are capable of producing tungsten alloy rods in various sizes and grades to meet customer needs. The process has been passed and accredited ISO9001. We have our own R&D team and can customize products according to customer requests. Tungsten rods generally need to be produced upon ordering, but we maintain stocks for common specifications in diameters such as 6mm, 10mm, 12mm, and 15mm with a surface grinding finishing.

AMS 7725 Tungsten Alloy Rod is an ideal choice for radiation shielding, ordnance parts, and high-temperature tools. We provide high-density tungsten alloys that offer a unique combination of density, mechanical strength, workability, and corrosion resistance.

Frequently Asked Questions

What are the main grades of your tungsten alloy rods?

Our rods primarily comply with ASTM B777-15 and AMS 7725 standards, available in various purity levels from 90% to 97% tungsten.

Can I order customized sizes for tungsten bars?

Yes, we can customize diameters ranging from 0.508mm (0.02") to 508mm (20") and offer various shapes like rods, bars, sheets, and plates upon request.

What is the difference between WNiFe and WNiCu alloys?

WNiFe is commonly used for general high-density applications, while WNiCu is preferred for non-magnetic applications such as electronic shielding or specific medical instruments.

What are the typical applications for high-density tungsten rods?

They are widely used in radiation shielding, aerospace counterweights, oil logging components, military ordnance, and sports equipment like golf club weights.

Do you provide quality certification with the products?

Yes, we provide a complete test report for every order, covering physical properties, chemical composition, and material density data.

How are the products packaged for international shipping?

We use standard export wooden boxes with internal foam protection to ensure the rods are secured and protected from damage during transit.
