Chemtube
Chemtube
The oxides of copper are removed from melts by the introduction of materials, which have a greater affinity for oxygen than has copper. The oxides formed are of such a nature that they separate easily from
the melt.
characteristics and features
The removal of oxygen from molten copper and its alloys increases metal fluidity and minimizes
the risk of gassy castings with low mechanical properties. ChemTube from a range of weighted products all
contained in pure copper or brass tubes, identified with Tube sizes. The contents of the tubes vary
depending upon the application for which they are required.

method of using
The metal should be melted down under the appropriate grade of ChemBlock, etc. Deoxidation operation
should be carried last before pouring. The selected tubes are introduced to the metal using a preheated
forked steel rod, plunged deep into the bottom of melt, and held there to allow their contents to become
absorbed. The metal is then stirred well, skimmed, and poured.
Advantages
- ChemTube is an easy method of making an accurate addition deep within the melt.
- Dispersion of ChemTube content is rapid and complete.
- Metal fluidity is improved and major causes of porosity in castings are eliminated.
Storage
Keep in a dry place and away from moisture.
Shelf Life
One year from the date of manufacture.
