IMT CuSn10 Spherical metal powder for 3D printing 15-53 microns 5 kg

Metal powder IMT CuSn10: the perfect tandem of copper and tin

IMT CuSn10 bronze powder is designed for the production of complex parts using the selective laser melting method. If you are engaged in mass production or prototyping of complex units, then IMT CuSn10 metal powder (tin bronze) will become a basic element of your technological stack. This is a high-tech product created specifically for laser melting systems (SLM/L-PBF). The alloy combines the viscosity of copper and the hardness of tin, giving engineers access to creating parts that were previously either too expensive to produce or technically impossible to cast.

Technical characteristics and chemical balance

IMT CuSn10 powder is a copper-tin alloy, where the share of copper is about 90% and tin is 10%. This ratio is ideal for obtaining wear-resistant and corrosion-resistant components.

Chemical composition and material physics

• Tin (Sn): 9–11% — provides the necessary hardness and strength.
• Copper (Cu): the base, guaranteeing electrical conductivity and ductility.
• Density: ~8.8 g/cm³, which is higher than that of pure copper due to alloying.
• Melting point: 1020–1040 °C.
• Tensile strength: 350–550 MPa.
• Elongation: 10–20%, allowing parts to withstand deformation loads without destruction.
• Ideal particle geometry: fraction 15–53 μm.

Why is the spherical shape important?

In metal 3D printing, the flowability of the powder determines the quality of each layer. Spherical particles of IMT CuSn10 minimize friction during recoater operation.

The 15–53 μm fraction is the industrial standard. It provides an ideal balance: the powder is fine enough for the particles to pack tightly (high bulk density), and heavy enough not to dust excessively inside the chamber. As a result, you get a stable melting process with a minimum number of micropores and defects in the structure of the finished product.

Features and benefits for users

• Process stability: due to the uniformity of the powder, printing parameters remain predictable from batch to batch.
• High detailing: the fine fraction allows for the elaboration of complex internal channels and thin walls.
• Anti-friction properties: parts made of CuSn10 work excellently in friction pairs.
• Resistance to aggressive environments: the material is not afraid of corrosion, especially in conditions of contact with salt water.

Areas of effective application

• Mechanical engineering: production of wear-resistant bushings, gears, and transmission elements.
• Electrical engineering: contact groups, terminals, and connectors.
• Shipbuilding: components of pumps, valves, and fasteners.
• Industrial design: creation of functional prototypes.

Recommendations for operation

The powder is supplied in a sealed container weighing 5 kg. To maintain the declared flowability and avoid oxidation, keep the packaging tightly closed in a dry place. Remember: moisture is the main enemy of finely dispersed powders. Subject to storage conditions, IMT CuSn10 guarantees impeccable surface quality and mechanical integrity of your products. Call us!
