FAQ
What is a tungsten square bar?
A tungsten square bar is a tungsten product with a square cross-section. It is commonly made from high-purity tungsten and used for applications requiring high-temperature resistance, high density, and dimensional stability.
What is the difference between tungsten square bar and tungsten rod?
The main difference is the shape of the cross-section. Tungsten square bars have a square profile with flat surfaces, while tungsten rods usually have a round cross-section. Square bars are suitable for flat-sided components and customized parts.
What sizes are available for tungsten square bars?
Tungsten square bars can be supplied in customized sizes, including cross-section dimensions, length, and tolerances. MATMETALS can manufacture products according to customer drawings or specifications.
Can tungsten square bars be customized?
Yes. Custom options include material grade, tungsten purity, dimensions, surface finish, and machining requirements. Tungsten square bars can be produced according to specific application needs.
How much does a tungsten square rod cost?
The price of a tungsten square bar depends on the material grade, purity, dimensions, quantity, surface finish, and machining requirements. Contact us for a customized quotation based on your requirements.
