Product FAQ's

How much does Tungsten Copper Alloy cost?

The Tungsten copper alloy price depends on tungsten content (W70, W75, W80, W90), bar size, density, machining requirements, and order quantity. Alloys with higher tungsten percentages cost more due to raw material density and processing complexity.

Do you supply copper tungsten alloy blanks for machining?

Yes. We are a reliable copper tungsten alloy blanks supplier, offering pre-machined blanks for industries that want to perform their own finishing or CNC work.

Can Tungsten Copper Alloy be customized?

Absolutely. We produce alloy copper tungsten components to your exact drawings, including EDM parts, heat spreaders, inserts, welding electrodes, and high-density structural components.

What information do I need to provide for custom tungsten–copper parts?

For custom machining we typically require:

2D/3D drawings
Tungsten content (e.g., W70Cu30, W80Cu20, W90Cu10)
Required tolerance and surface finish
Application (EDM, contact, thermal, etc.)
Whether you need blanks or fully machined parts

Do you provide material certifications for tungsten heavy alloy?

All Tungsten copper alloy products come with material certification, chemical composition reports, and inspection documentation upon request.
