Tungsten Steel Die

What Is a Tungsten Steel Die?

A tungsten steel die, also known as a tungsten carbide die, is a precision tooling component made from cemented tungsten steel. It is used for drawing, extruding, heading, and forming metal wire, rod, and tube where high wear resistance and dimensional accuracy are required.

Renyuan Mould manufactures precision tungsten steel dies that deliver long service life and consistent part quality in high-volume production.

Advantages of Tungsten Steel Dies

Tungsten steel dies offer exceptional hardness, high compressive strength, and excellent abrasion resistance. They maintain precise dimensions and polished surfaces over millions of cycles, reducing die change frequency and improving production efficiency.

The material also provides good thermal stability and corrosion resistance, making it suitable for ferrous and non-ferrous metal forming.

Types of Tungsten Steel Dies

We produce wire drawing dies, bar drawing dies, tube drawing dies, cold heading dies, extrusion dies, and profile dies. Each die is manufactured to the customer's specific application and part geometry.

Die entry angles and bearing lengths are optimized for smooth material flow and maximum die life.

Die Grades

Fine-grain grades are used for fine wire drawing and precision finishing. Medium-grain grades balance wear resistance and toughness for general drawing. Coarse-grain grades handle heavy bar and tube drawing with high impact loads.

We can supply dies in customer-specified grades according to ISO standards.

Precision and Surface Finish

Die bore tolerances of plus or minus 0.002 millimeters are achievable. Internal surfaces can be polished to Ra 0.05 or better, ensuring excellent surface finish on drawn parts and smooth material passage.

Applications

Tungsten steel dies are widely used in steel wire, welding wire, copper wire, aluminum wire, fastener, automotive tube, and construction wire production. They are essential in any process requiring long die life and consistent dimensions.

Custom Die Design

Renyuan Mould offers custom die design based on customer drawings, samples, or material specifications. Our engineering team assists with profile optimization, grade selection, and entry angle design to maximize die performance.

Quality and Delivery

Each die is inspected for diameter, hardness, surface finish, and visual defects. Dies are protected with anti-rust coating and packed securely for international shipping. Standard lead time is two to four weeks.
