Basic materials for all alloys are raw matals like copper,nickel,cobalt,chorme,beryllium,zircon etc.They are untegrated according to their weight and then filled into the melting pot of the vacuum furmace.

The process of re-charging will be performed through a lock chamber during the melting operation

Then,the process goes into forging,rolling,pressing and drawing.

The ingots are transformed into semi-products.

Subsequently,these ingots will be heat-treated.
