Technological Breakthrough: Domestic Copper & Aluminum Casting Technology Makes Progress, Localization of Copper and Aluminum Castings Accelerates
1. Multiple Patents Granted for Copper Alloy Casting Equipment
In mid-May, Luoyang Copper Processing obtained a national utility model patent for the Horizontal Coreless Insulated Pouring Furnace.
After equipment upgrading, the annual output of bronze and white copper ingots reaches 24,000 tons, bringing an annual benefit increase of 12 million yuan.
This tackles the bottleneck in casting equipment for copper alloy castings, and meets the production requirements for special copper castings used in military industry and precision instruments.
2. Mass Production Realized for Steel-Aluminum Composite Casting Technology
Zhangqiu Copper & Aluminum Foundry in Shandong has overcome the technical difficulty of welding dissimilar steel and aluminum metals.
The machining error on the bonding surface of castings is controlled within ≤0.02 mm (precision equivalent to one quarter of a human hair).
It realizes molecular-level composite forming of aluminum castings and steel structures.
The products have obtained European and American certifications, and are supplied in batches to military and construction machinery sectors, breaking the overseas monopoly on composite castings.
