Frequently Asked Questions
What materials and process are used for Copper Tungsten Welding Tips?
Copper Tungsten Welding Tips is made from Tungsten copper (W-Cu), W70Cu30 / W80Cu20 / W90Cu10 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 Copper Tungsten Welding Tips?
Typical specifications: Grades: W70Cu30 / W80Cu20 / W90Cu10; Process: PM/MIM infiltration, near-net-shape / PM/MIM 渗铜近净成形. 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 Copper Tungsten Welding Tips?
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.
