DE2620831

A process for the production of oxygen free copper castings and moldings, which contain 0.05 to 0.2% by weight of boron as micro-alloy element, by deoxidation of oxygen containing copper melts by means of calcium hexaboride, comprising introducing 0.3-1% by weight of a CaB6 into the copper melt, the...

More Information
Summary:A process for the production of oxygen free copper castings and moldings, which contain 0.05 to 0.2% by weight of boron as micro-alloy element, by deoxidation of oxygen containing copper melts by means of calcium hexaboride, comprising introducing 0.3-1% by weight of a CaB6 into the copper melt, the CaB6 containing at least 3% C calculated on the weight of the CaB6, subsequently subjecting the cooled melt, if desired while molding the same, to a solution annealing operation and following up with a storage for an extended time.
