Import Cast Tungsten Carbide Powder — Buy in Bulk from Supplier in China

Cast tungsten carbide powder from Phildal Tungsten Co., Ltd. is a finely ground material derived from sintered tungsten carbide ingots, processed to achieve controlled particle size distributions for powder metallurgy applications. Unlike solid cast blocks, this form is intended for pressing and sintering into complex components such as cutting inserts, wear plates, and drill bit tips. The powder retains the hardness and thermal stability of tungsten carbide but allows for near-net-shape manufacturing.

Particle size distribution is cited as application-specific, though no exact ranges are provided. Standard industrial grades for this powder typically fall between 1 to 10 microns for high-precision tools, or 10 to 50 microns for heavy-duty wear parts. The material is not alloyed with nickel or chromium, and binder content is added during downstream compaction, not in the powder stage. The source mentions compliance with ISO and ASTM standards, but does not specify which ones.

This powder is purchased by manufacturers of cemented carbide tools, mining equipment producers, and aerospace component fabricators who require consistent sintering behavior. Buyers in the oil and gas sector use it for drill bit inserts exposed to abrasive rock formations. Trade terms include FOB and CIF shipping, with L/C and T/T payment options. Minimum order quantities are described as flexible but are not quantified, so buyers must request exact thresholds before committing.

Phildal Tungsten Co., Ltd. is located in Changzhou, Jiangsu Province, China, at No.5 Qingjiang Road. The supplier is classified as imported with harbor trust tier, indicating documented export history and logistics capability. No details are provided on factory size, years in operation, workforce, or internal quality control systems. The listing confirms production and export of tungsten carbide powder but offers no evidence of R&D, lab testing, or customer-specific formulation services.

The supplier’s response rate and average response time are recorded as zero, indicating no recent buyer inquiries on the platform. This does not imply unresponsiveness but reflects a lack of digital engagement. Buyers should assume this is a direct manufacturer without third-party verification of powder processing. Claims of ISO and ASTM compliance are mentioned in the source description but are not substantiated by the supplier’s profile and must be confirmed via documentation.
