Tin Bronze Powder (CuSn10 Powder, Copper Tin Alloy Powder)
CuSn10 powder is a copper-based alloy containing 10% tin and 90% copper, commonly referred to as tin bronze powder. This alloy is widely used for its excellent wear resistance, good thermal conductivity, high strength, and superior corrosion resistance, especially in marine and moist environments. The spherical CuSn10 powder produced via gas atomization ensures high flowability and uniform density—ideal for metal 3D printing, powder metallurgy, and thermal spraying applications.
At Princeton Powder, we specialize in producing high-quality metal powders for advanced manufacturing applications. Our CuSn10 spherical bronze powder is engineered for performance, reliability, and consistency. With rapid delivery, technical support, and competitive pricing, we’re your trusted partner in 3D printing powder solutions.

Corrosion Resistance of 316L/CuSn10 Multi-Material Manufactured by Powder Bed Fusion
- by combining 316L and CuSn10, 316L’s high mechanical–technological and corrosion-resistant properties can be combined with the good thermal conductivity of the copper-based alloy. This is a promising solution for, e.g., complex cooling channels in various applications [5,6]. However, joining materials with significantly different thermophysical properties is challenging and can lead to insufficient adhesion between materials during use [7]. Therefore, a sufficient diffusion layer between two materials is beneficial, as it creates a strong bonding and a smooth transition into each other. Powder Bed Fusion (PBF), which belongs to the Metal Additive Manufacturing (MAM) processes, is particularly suitable.
