IMT CuCrZr Spherical Copper Powder 15–53 μm, 5 kg

IMT CuCrZr 15–53 μm: Spherical Copper Powder for High Thermal and Electrical Conductivity

IMT CuCrZr is a copper-based metal powder alloyed with chromium and zirconium, specifically designed for 3D printing using SLM/LPBF technology. The alloy combines high thermal conductivity (over 280 W/m·K) and electrical conductivity with good mechanical properties. This makes it an optimal choice for manufacturing components of cooling systems, heat exchangers, and electrical parts.

Fraction of the powder 15–53 μm is characterized by high sphericity (≥ 90%), ensuring stable flowability (≤ 20 s/50g) and uniform layer application during printing.

Packaging: airtight container 5 kg.

Material Technical Profile

1. Chemical Composition

The CuCrZr (Copper Chromium Zirconium) alloy has a balanced composition to achieve maximum conductivity after heat treatment:

• Copper (Cu): base (Balance) — provides exceptional thermal and electrical conductivity.
• Chromium (Cr) and Zirconium (Zr) — alloying elements that enhance the mechanical strength and hardness of the alloy without significant loss of conductivity.

2. Physical Properties of the Powder

Indicators ensure the stability of the additive manufacturing process:

• Sphericity: ≥ 90%.
• Flowability (Hall flow): ≤ 20 s/50g.
• Tap Density: ≥ 5.2 g/cm³.
• Oxygen Content: ≤ 500 ppm.

3. Mechanical and Thermophysical Properties

Product characteristics at normal temperature:

• Tensile Strength: ≥ 350 MPa.
