The output of steel castings in China has continued to grow since 2000 and is widely used in internal combustion engines, agricultural machinery, automobiles, machine tools, textile machinery, urban construction and other fields. In 2015, the output of gray cast iron was 12.3 million tons, an increase of 42% compared with 2010, accounting for 30% of the world’s gray iron output; The output of nodular cast iron is 5.84 million tons, an increase of 150% over 2000, accounting for 30% of the world’s output of nodular cast iron; The output of malleable cast iron is about 510000 tons, an increase of 31 ∙ 4% over 2000, accounting for 41 ∙ 7% of the world’s output of malleable cast iron.
The output of steel castings in China has also continued to grow since 2000, reaching 3.22 ∙ 40000 t in 2015, accounting for 35 ∙ 8% of the world output. It is widely used in the fields of heavy machinery, railway transportation, engineering machinery, electronic equipment, pump and valve industry. The output of nonferrous alloy castings in China has increased rapidly since 2000, reaching 2.54 million tons in 2016, an increase of 144 ∙ 7% over 2000. This kind of casting has a very good application prospect, especially aluminum magnesium alloy.
