CuSn10 Bronze Alloy Powder for Laser Cladding, DED Additive Manufacturing, Marine, Automotive & Industrial Wear-Resistant Components
Product Overview
GREENSTONE CuSn10 bronze alloy powder is a copper-tin alloy powder containing approximately 10% tin, developed for laser cladding, Directed Energy Deposition (DED), metal additive manufacturing, thermal spray and industrial surface engineering applications.
CuSn10 combines good wear resistance, corrosion resistance, low-friction behavior, thermal conductivity and machinability. These properties make it particularly suitable for manufacturing, repairing and surface-enhancing bearings, bushings, gears, valves, sliding components and other friction or wear-resistant parts.
With controlled particle size distribution and powder morphology optimized for industrial processing, GREENSTONE CuSn10 provides reliable material feeding and consistent deposition performance for applications across marine engineering, automotive manufacturing, heavy machinery, industrial equipment and general mechanical engineering.
CuSn10 Copper-Tin Bronze Alloy
CuSn10 is a widely recognized tin bronze alloy consisting primarily of copper with approximately 10% tin. The addition of tin improves the strength, hardness, wear resistance and corrosion resistance of copper while maintaining useful machinability and tribological properties.
This combination makes CuSn10 particularly suitable for components subjected to sliding contact, friction, mechanical wear and corrosive operating environments.
Excellent Wear and Friction Performance
CuSn10 provides good wear resistance and low-friction characteristics, making it suitable for bearing and sliding surfaces where stable long-term operation is required.
Typical components include:
- Bearings and bushings
- Sliding surfaces
- Gears and transmission components
- Guide components
- Valve components
- Wear-resistant mechanical parts
Good Corrosion Resistance
Tin bronze provides good corrosion resistance in many industrial and marine environments. This makes CuSn10 powder useful for marine equipment, pumps, valves, mechanical components and corrosion-resistant surface restoration.
Suitable for Laser Cladding and DED
GREENSTONE CuSn10 powder can be deposited onto metallic substrates using laser cladding and powder-fed DED to manufacture functional surfaces or restore worn components.
Laser processing allows material to be applied selectively to critical areas, helping reduce material consumption while producing metallurgically bonded functional layers.
Typical applications include dimensional restoration, localized repair, bearing-surface rebuilding and wear-resistant surface modification.
Metal Additive Manufacturing Capability
Controlled powder morphology and particle size distribution make CuSn10 suitable for compatible metal additive manufacturing and DED processes. Depending on the manufacturing technology, particle size distribution can be customized to meet powder feeding or powder-bed requirements.
Good Machinability
Deposited or additively manufactured CuSn10 components can be subsequently machined to achieve required dimensions and surface finish, making the alloy particularly useful for precision repair and remanufacturing.
Good Thermal Conductivity
As a copper-based alloy, CuSn10 retains useful thermal conductivity while providing significantly improved mechanical and wear properties compared with pure copper in many engineering applications.
