Product Introduction

Powder Introduction

Cu15Ni8Sn powder is a high-performance copper–nickel–tin alloy powder, primarily used in powder metallurgy to produce high-strength, wear-resistant components. It serves as an environmentally friendly alternative to beryllium bronze. After compaction, sintering, and heat treatment, this material attains exceptionally high hardness and strength while maintaining excellent electrical conductivity and corrosion resistance, making it particularly well suited for manufacturing precision electronic components and wear‑resistant parts.

Application areas

1. Aerospace

• Aircraft landing gear joint bearings, bushings, and heavy-duty, wear-resistant, self-lubricating components;

• Sealed valve assemblies for airborne hydraulic systems, high-temperature elastic springs, and wear-resistant fittings for fluid lines;

2. Weapons and Naval Vessels

• Wear-resistant valve components for shipboard seawater piping, bearings for underwater equipment, and propeller seal bushings;

• Corrosion- and wear-resistant downhole valve bodies for offshore oil and gas platforms, as well as high-pressure heat-exchanger components for seawater desalination;

• Non-magnetic sensor housing for submarines; heavy-duty, wear-resistant sliding friction pairs;

3. Heavy equipment, construction machinery

• Wear-resistant bushings for hydraulic pumps, heavy-duty bearings for construction machinery, and wear-resistant gear liners;

• Laser cladding of wear-resistant coatings on injection molding and die-casting molds to repair worn parts and extend their service life.
