Pure Tungsten Rod

Product Introduction

The Pure Tungsten Rod offered by Shaanxi Chuanghui Daye Metal Material Co., Ltd. is manufactured using high-purity tungsten powder and advanced powder metallurgy technology. With an impressive melting point of 3410°C and excellent high-temperature strength, it is ideal for use in demanding industrial environments such as vacuum furnaces, lighting, and semiconductor applications. The Pure Tungsten Rod demonstrates superior thermal conductivity, high density, and outstanding resistance to erosion and deformation, making it a preferred choice for high-precision machining and thermal applications. Available in polished, ground, or centerless-finished surfaces, our tungsten rods meet ASTM, ISO, and GB standards to ensure consistent performance and reliability.

Tungsten is a rare non-ferrous metal, and tungsten rods have high density, high melting point, high hardness, good electrical and thermal conductivity, as well as excellent corrosion resistance.

Chemical composition

Dimension and tolerance

• Heavy Density

• Free cutting processing

• Excellent mechanical performance

• High elastic modulus

• Can effectively absorb xrays and gamma rays

(for the absorption of x rays, and gamma rays than lead high about 30% - 30%) no harm to envirnment and health.

Application 

Tungsten rods have special properties such as low thermal expansion and good thermal conductivity, sufficient electrical resistance, and high elastic modulus. Therefore, tungsten rods are widely used in various fields. Such as support wires, import wires, printer needles, various electrodes and quartz furnaces, filaments, high-speed tools, automotive automation products, sputtering targets.

Be used in a wide range of industries.

Manufacturing & Process Flow

The production of the Pure Tungsten Rod involves a series of controlled steps to ensure structural integrity and high density:

1. Raw Material Selection: Only high-purity tungsten powder (≥99.95%) is selected.
2. Pressing & Sintering: The powder is pressed into bars and sintered under hydrogen or vacuum at temperatures above 2500°C.
3. Swaging & Forging: The sintered bars are forged and swaged to achieve required mechanical strength.
4. Machining & Finishing: Precision grinding, polishing, or centerless finishing ensures dimensional accuracy.
5. Inspection & Packaging: Each rod undergoes multiple inspections before export-standard packaging.

Every production stage is closely monitored by experienced engineers to ensure compliance with international standards.

Quality Control & Inspection​​​​​​​​​​​​​​

Quality assurance is at the heart of Shaanxi Chuanghui Daye’s manufacturing philosophy. Our Pure Tungsten Rod production strictly follows ISO 9001:2015 quality management principles.

• Raw Material Test: Each batch of tungsten powder is tested for purity and particle size distribution.
• Dimensional Accuracy: Micrometer and ultrasonic testing ensure uniform diameter and structural integrity.
• Mechanical Testing: Includes tensile strength, density measurement, and hardness verification.
• Surface Examination: Visual and microscopic inspection prevents surface defects or cracks.
• Final Review: Each rod is labeled with batch numbers and test certificates before shipment.
