Copper coated graphite composite powder

Summary

LF141 copper coated graphite composite powder is a powder made of copper and graphite, which have good conductors of electricity. But they share a difference specific gravity of more than 4 times. The two combined into one whole powder that can overcome a lot because of different specific gravities or graphite surface due to poor wettability of metal brought problems.

Graphite is commonly used additive powder metallurgy carbon elements, when mixed with other metals, because the proportion of metals (especially iron) difference between the larger, can easily lead to uneven segregation ingredients and mix. As the carbon additive during the sintering process and other metal lubricity is poor, resulting in deterioration of the mechanical properties of the sintered body. After the surface of the graphite particles coated with a layer of copper, chemical bond is formed between the two above-mentioned drawbacks will be solved.
