Product Introduction

At present, China's copper processing flow control mainly uses graphite stopper, due to the poor oxidation resistance of graphite material, life is only 1 to 3 days, the production organization of copper processing enterprises to bring greater trouble. The chrome corundum stopper developed by our company has high oxidation resistance, copper erosion resistance and permeability, and high thermal shock stability. It is an ideal material to replace the graphite stopper.
