Aluminum prices under pressure, rising costs exacerbate the cold winter in the aluminum alloy ingot market

As 2017 approaches its end, spot aluminum ingot prices did not see the expected rise, but rather a change in the issue of production cuts during the heating season. This also brought significant impact to aluminum alloy ingot enterprises; on the one hand, aluminum alloy ingot prices fell in response, and on the other hand, scrap aluminum prices fell slowly. As the year-end approaches, various regions have successively experienced a 'gas shortage,' natural gas prices have risen, and the supply of aluminum alloy ingots has decreased. Facing such a situation, can the consumption of aluminum alloy ingots achieve a breakthrough? Can the price of aluminum alloy ingots be supported by the end of the year? Currently, scrap aluminum, as a raw material, has begun to show signs of shortage in terms of supply. Can be used to produce aluminum alloy

Increased primary aluminum consumption: Can aluminum alloy ingots shine?

As 2018 arrived, spot aluminum ingot inventories remained high, downstream consumption showed no highlights, and overall market demand was weak. This resulted in aluminum prices remaining in a low-level range even with production restrictions during the heating season. Against this backdrop, everyone has focused their attention on the post-holiday period. With the commissioning of new electrolytic aluminum production capacity, will the downstream consumption end see a recovery or new growth points, and will aluminum prices rise ahead of schedule? We will analyze the demand for the aluminum alloy ingot market as follows. Currently, aluminum alloy ingots are divided into primary aluminum and recycled aluminum. First, we will analyze primary aluminum, mainly A38

Are there still opportunities for importing aluminum alloy ingots in 2020?

A reduction in import permits for waste aluminum in the fourth quarter, coupled with a slight recovery in downstream demand, led to a shortage of domestic waste aluminum, causing a significant price increase in domestic ADC12 aluminum alloy ingots. With the waste aluminum shortage, various import and export companies became relatively active, resulting in a large influx of imported aluminum alloy ingots into the domestic market. The heat only subsided recently when domestic ADC12 prices peaked, while overseas ADC12 prices rose significantly, and import permits for waste aluminum increased substantially in Q1 2020. So, are there still opportunities for imported aluminum alloy ingots in 2020?

Chemical segregation in ingots

I. Chemical Segregation in Cast Ingots The phenomenon of uneven chemical composition distribution in cast ingots is called segregation. In deformed aluminum alloys, segregation is mainly divided into intragranular segregation and inverse segregation. 1.1 Intragranular Segregation The phenomenon of uneven chemical composition within grains in the microstructure is called intragranular segregation. The microstructural characteristics of intragranular segregation are that after etching, the inside of the grain shows a wavy pattern similar to tree rings. The microhardness within the grain is different, with high microhardness near the grain boundary and low microhardness in the center of the grain. The existence of intragranular segregation makes the chemical composition and structure of the ingot extremely uneven, resulting in a serious deterioration of the ingot's properties, mainly: 1) Solid solution

Gases and non-metallic inclusions in ingots

Non-metallic inclusions (inclusions) are slags mixed into ingots or other non-metallic impurities that fall into ingots. The fracture characteristics are black stripes or flakes, and the microstructure characteristics are mostly black linear, blocky, and flocculent disordered structures, with a significant color difference from the matrix. Non-metallic inclusions are an important reason for the delamination and many surface defects of aluminum processed products. During heat treatment and heating, the presence of non-metallic inclusions can promote the formation of secondary porosity and bubbles. In terms of mechanical properties, non-metallic inclusions are stress concentration sites, reducing the ultimate tensile strength and elongation of the alloy. In particular, the transverse elongation and dynamic mechanical properties (impact
