When we talk about the coefficient of thermal expansion of aluminum-silicon alloys, we're essentially discussing the degree of volume change of the material with temperature variations. The coefficient of thermal expansion is typically described in terms of the change in volume per degree Celsius (or per Kelvin) of temperature change, indicating the material's expansion or contraction rate.
Aluminum-silico
In the fourth quarter of 2023, various restrictions were imposed on the domestic raw material market, resulting in insufficient operating rates for mines and alumina enterprises, and a noticeable decline in raw material production. The supply of spot alumina was insufficient, leading to instances of extended delivery times for some enterprises. Some downstream users began to turn to imported alumina, while domestic r
According to data from the International Aluminium Institute, global primary aluminum production in February 2024 was 55.44 million tons, compared to 53.34 million tons for the same period last year and a revised figure of 60.62 million tons for the previous month. The daily average production of primary aluminum in February was 191,200 tons, down from 195,500 tons in the previous month. China's primary aluminum
The Ministry of Industry and Information Technology, along with six other departments, has issued guiding opinions on accelerating the green development of the manufacturing industry. Among them, there is a proposal to promote short-process technology in industries such as steel, petrochemicals, non-ferrous metals, textiles, and machinery. The guidance aims to establish a market-oriented and rule-of-law mechanism for
