What is precision casting technology for light alloys？

Light alloys, including aluminum, magnesium, titanium, and other alloys, have been extensively researched and applied in industries such as aerospace, shipbuilding, chemical engineering, and instrumentation due to their low specific gravity, corrosion resistance, and high specific strength. Especially, various precision castings prepared using precision casting technology account for a large proportion, which makes light alloys and their precision casting forming technology the preferred materials and manufacturing technologies for achieving lightweight, low-cost, low-energy consumption, short cycle and other goals in the current and future equipment industry. It is also a question of whether a country's equipment industry is strong. Is it a sign of technological advancement.

The working temperature and strength of cast aluminum alloy are between titanium alloy and magnesium alloy, with a working temperature generally below 300 ℃ and a tensile strength generally below 400 MPa. It is mainly used in industries such as aerospace and automotive. The development of aluminum alloy casting and forming technology is mature, and its main casting and forming technologies include pressure casting technology, semi-solid forming technology, vacuum suction casting technology, investment casting technology, resin sand mold technology, gypsum mold casting technology, metal mold casting technology, etc.

The working temperature and strength of cast magnesium alloy are the lowest among the three, with a working temperature generally around 100 ℃ and a tensile strength generally below 300MPa. It is mainly used in industries such as instrumentation. The development of magnesium alloy casting technology is relatively late. Its main casting technologies include pressure casting technology, vacuum suction casting technology, investment casting technology, resin sand casting technology, gypsum casting technology, etc.
