Copper Alloy Powder Metallurgy Gears
Copper alloy PM gears engineered for motion systems that demand quiet operation, excellent dimensional control and high thermal stability — compacted and sintered to a microstructure far more uniform than cast or machined copper alloys.
- Materials
- Copper-based PM alloys
- Features
- Quiet meshing, controlled pore network for lubrication retention, high thermal stability, minimal post-machining
- Application
- Micro-motors in smart appliances, precision reduction units for miniature robots and actuators, silent drive modules in office equipment, small automotive auxiliary systems, consumer electronics.
Frequently Asked Questions
What materials and process are used for Copper Alloy Powder Metallurgy Gears?
Copper Alloy Powder Metallurgy Gears is made from Copper-based PM alloys 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 tolerances can Copper Alloy Powder Metallurgy Gears hold?
Typical as-sintered dimensional tolerance is ±0.3–0.5% of the dimension. Tighter tolerances are achievable with secondary sizing or machining, agreed per part during quoting.
What is the MOQ and lead time for Copper Alloy Powder Metallurgy Gears?
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.
