From 2013 to 2019, the overall output of castings in China presents a fluctuating trend. Among them, China's production of various types of castings in 2019 was 48.75 million tons, with a year-on-year decrease of 1.2%. But on the whole, the industry output is at a high level
According to the distribution of casting output of different materials, gray cast iron still occupies the main position, accounting for 41.85%. It is worth noting that in 2019, the output of steel castings will reach 5.9 million tons, accounting for 12.1% of the total output, an increase of 0.45% compared with that in 2018, which is mainly driven by the rapid development of downstream rail transit, construction machinery, mining and metallurgy heavy machinery and other industries. In addition, the output of ductile iron and aluminum (magnesium) alloy will decline in 2019, which is mainly affected by the decline of automobile industry
