In advanced material applications, even trace impurities can affect process performance and the properties of the finished product. C-KOE Metals supplies high purity aluminum with guaranteed purity levels up to 99.99% Al for manufacturers requiring tightly controlled chemistry and dependable material consistency.

Select production lots may test above 99.99% Al, occasionally reaching 99.999% Al. These higher-purity lots are offered on a lot-specific basis, with actual chemistry documented on the Certificate of Analysis.

Available in pellets, bar, and grain, our aluminum supports high purity alumina, sapphire materials, semiconductor materials, electronic materials, and other advanced applications where impurity control is critical.
