FAQ
Q1: What is the main advantage of using spherical copper powder over irregular shapes?
A1: Spherical copper powder offers excellent flowability and high packing density. This is crucial for consistent layer spreading in 3D printing and uniform filling in molds for powder metallurgy, leading to higher quality, more reliable, and denser final products.
Q2: How is the purity of 99.99% ensured in your copper powder?
A2: Our copper powder is produced under strict quality control protocols and is certified to meet ISO and ASTM standards. The composition is rigorously tested, with trace element levels (like Fe, Pb, As) kept to a minimum, as shown in the product parameters, guaranteeing high purity for sensitive applications.
Q3: Can I request a specific particle size distribution for my application?
A3: Yes, absolutely. We specialize in customizing particle size distributions to meet specific customer needs. Standard ranges like 15-53µm for 3D printing are available, and we can work with you to develop a powder tailored to your unique process requirements.
Q4: How should this copper powder be stored to maintain its quality?
A4: To prevent oxidation and maintain quality, the powder should be stored in a tightly sealed container in a cool, dry, and well-ventilated place. We typically use vacuum packaging to ensure the product arrives in perfect condition.
Q5: What are the packaging options available?
A5: Standard packaging is 25kg per drum or bag. For smaller R&D or sample quantities, we can package the powder in foil-aluminum bags, bottles, or other containers upon request to suit your needs.
