High Purity Copper Grains

High purity copper grains are a kind of metal copper particles with purity above 99.999%. It is an intermediate material used to prepare high-purity copper target and high-purity copper wire, which is mainly used in semiconductor, electronics, optoelectronics and other fields. It is an important raw material to improve the quality and performance of products.

High purity copper grains have the following characteristics：

• Smooth surface, high density, no tissue defects, good homogeneity
• Uniform particle size, easy to process and use.
• High purity, low impurity content, can ensure product uniformity and consistency.
• Excellent electrical conductivity, low resistivity, can be used to make high-performance cables, bonded wire, etc.
• Excellent oxidation resistance, not easy to rust, can extend the service life, maintain good connection performance.

Specifications for high purity copper grains：

• Shape: spherical, flaky, irregular shape, length, diameter can be customized according to customer requirements
• Purity: 5N (99.999%) or 6N (99.9999%) or 6N5 (99.99995%)
