Frequently Asked Questions
What materials and process are used for Tungsten Heavy Counterweight?
Tungsten Heavy Counterweight is made from W-Ni-Cu / W-Ni-Fe tungsten heavy alloy and is formed by MIM/PM (metal injection molding / powder metallurgy) near-net-shape and sintered to a relative density of ≥ 98%, which keeps mechanical properties close to wrought material.
What are the key specifications of Tungsten Heavy Counterweight?
Typical specifications: Composition: W-Ni-Cu / W-Ni-Fe; Machining Tolerance: ± 0.005 mm; Concentricity: ≤ 0.002 mm. The full parameter list is in the specifications table on this page; custom requirements can be discussed against your drawing.
What is the MOQ and lead time for Tungsten Heavy Counterweight?
MOQ is 1000 pcs. Mold lead time is about 20 days (mold fee typically RMB 20–40k depending on part geometry), and production lead time is about 7 days once the mold is validated; secondary processing adds 3–5 days.
