The materials suitable for lost wax casting are mainly high temperature alloys, titanium alloys and more. Of course, the best metal for lost wax casting is copper.
1. Suitable materials
The materials commonly used for lost wax casting are: copper, aluminum alloy, magnesium alloy, chromium alloy, titanium alloy, stainless steel, high temperature alloy, etc. These materials have good fluidity, high strength, thermal stability and mechanical properties, and are not prone to defects such as deformation and shrinkage during lost wax casting.
Among them, high temperature alloys and titanium alloys are the most suitable materials for lost wax casting. High temperature alloys are alloys that can maintain good performance at high temperatures and are widely used in the manufacture of parts in the fields of aviation, petroleum, aerospace and more. In lost wax casting, suitable high temperature alloy formulas and casting processes can produce parts with high strength, high temperature stability and corrosion resistance. Similarly, titanium alloys have the advantages of high strength, low density, corrosion resistance and more, and are suitable for manufacturing high-precision parts in the fields of aerospace, medical equipment and more.
2. Why choose these materials
Lost wax casting is a high-precision process method that requires materials to have good fluidity, low shrinkage, and uniform shrinkage. Even non-metallic materials need to have similar characteristics. When selecting materials, factors such as the chemical composition, melting point, and thermal expansion coefficient of the material need to be considered. Although materials such as aluminum alloys, magnesium alloys, and chromium alloys are also suitable for lost wax casting, their shrinkage is high, and defects such as shrinkage cavities and shrinkage porosity are prone to occur during the casting process.
For high-temperature resistant alloys and titanium alloys, they not only have good fluidity and mechanical properties, but also can withstand thermal expansion and thermal stress at high temperatures. Even in high temperature environments, they are not easy to deform and crack, so they are more suitable for lost wax casting.
Lost wax casting is a commonly used process method that is suitable for manufacturing complex shapes and high-precision castings. When selecting casting materials, factors such as the chemical composition, melting point, and thermal expansion coefficient of the material need to be considered. High-temperature resistant alloys, titanium alloys, and other materials have good fluidity, high strength, thermal stability, and mechanical properties, are suitable for lost wax casting, and can produce high-precision, high-quality parts.
