Precision Casting Solutions from China

Yes, there is a difference. Generally speaking, even for the alloy of the same brand, the content of components may vary slightly depending on the casting process used. Each process has specific requirements for fluidity, shrinkage, and solidification characteristics, which may lead to minor adjustments in alloy composition to optimize performance.

In the process of aluminum alloy casting, the selection of sand is very important. The sand should have good refractoriness to withstand aluminum's pouring temperature (typically 660-750°C), appropriate permeability to allow gas escape, and sufficient strength to maintain mold integrity. Silica sand with proper binder systems is commonly used, with grain size and distribution carefully controlled to achieve the desired surface finish and dimensional accuracy.

Gravity casting typically produces parts with lower porosity and better mechanical properties due to slower filling and solidification. It's ideal for components requiring heat treatment. Die casting offers higher production rates, better dimensional accuracy, and superior surface finish, making it suitable for high-volume production of complex, thin-walled parts.

Our casting products serve a wide range of industries including automotive, industrial machinery, electrical equipment, construction, marine applications, and general engineering. Our aluminum and copper castings are used in components requiring durability, thermal conductivity, or electrical conductivity.
