Frequently Asked Questions
What materials and process are used for Tungsten Alloy Spacecraft Attitude Control Counterweight?
Tungsten Alloy Spacecraft Attitude Control Counterweight is made from W-Ni-Fe (space grade) 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 Alloy Spacecraft Attitude Control Counterweight?
Typical specifications: Material Grade: W-Ni-Fe (Space Grade); Density: 17.8 – 18.5 g/cm³; Vacuum Stability: Zero Outgassing (CVCM < 0.1%). 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 Alloy Spacecraft Attitude Control 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.
