2618 Aluminum plate forgings

2219 aluminum alloy belongs to aluminum-copper-manganese medium-high strength aluminum alloy. It has good high and low temperature mechanical properties, weldability, fracture toughness, corrosion resistance and easy processing. It is a typical heat treatable forged aluminum alloy. Products are used in aerospace, aerospace and other fields in different forms and heat treatment conditions. Large-size 2219 aluminum round rod are mainly used to make forged rings. The process route is: forging blank-punching-hot ring milk-quenching-cold milk-artificial aging. With the advancement of domestic smelting, degassing, casting and other technologies and the continuous improvement of customers' specifications and performance, the specifications of 2219 aluminum round rod are getting larger and larger, and the traditional medium specifications can no longer meet the needs. Oversized round ingots.

The key to the production of oversized round ingots is the control of casting and internal metallurgical quality. However, as the ingot specifications increase, segregation, coarse grains, loose, cracks, coarse metal compounds, and brightness are easily generated during casting. Metallurgical defects such as crystal and feather crystal, casting molding and metallurgical quality are difficult to guarantee. Therefore, it is urgent to study the preparation method of the oversized 2219 ingot to meet the market demand.

Chalco aluminum overcomes the shortcomings of smelting and casting technology, and improves the raw material selection, smelting, degassing in the furnace, on-line degassing, on-line filtration, casting, etc., improving the quality of ingots and improving production efficiency, thus enabling stable production of oversized specifications. 2219aluminum round rod, this aluminum rod can produce 2219 aluminum rod bar,2219 aluminum block,2219 aluminum ring,2219 aluminum cake and so on.
