High Thermal Conductivity And Strong Physical Stability Of Gemstone Sand

Our company specializes in supplying sintered alumina sand (also known as gemstone sand, fused alumina, or ceramsite sand). Our product boasts stable and reliable quality, representing a high-quality new type of raw sand for the foundry industry. It is widely compatible with various casting processes, including investment casting, lost foam casting, and other casting techniques. It is also a preferred raw material for precision casting, coated sand, and self-hardening sand production. Furthermore, it can be used for shot peening of aluminum, copper, and steel castings.

This product is refined from high-quality aluminum ore through high-temperature calcination, electrofusion forming, and high-pressure atomized cutting processes. Its cost-effectiveness far surpasses that of zircon sand and chromite sand. The product possesses excellent characteristics such as low expansion, non-sintering, non-pulverization, non-cracking, and non-sticking, eliminating potential casting quality issues at the source. It also exhibits excellent recyclability, effectively improving casting yield and reducing production costs while increasing efficiency.

Core Product Advantages:
* Low coefficient of thermal expansion, performance comparable to zircon sand; casting products made with this sand are free of expansion defects.
* Perfectly spherical sand particles offer excellent flowability and permeability, resulting in superior molding performance.
* Smooth surface and dense structure ensure even coating of adhesives, enhancing bonding stability.
* Neutral material properties, compatible with various acidic and alkaline adhesives, offering wide applicability.
* Highly recyclable and cost-effective: priced at only 30-50% of zircon sand and chromite sand; the small surface area of ​​the spherical sand

particles reduces the amount of resin required. With a water glass content of ≤4% (30-50%), significantly reducing raw material costs and minimizing casting defects caused by binders, this product boasts high refractoriness and easy disintegration, with a mullite phase content far exceeding that of sintered products, resulting in excellent refractoriness. It also exhibits high thermal conductivity and strong physical stability, preventing cracking under high temperatures and adapting to complex casting conditions.

Its wide range of applications includes lost foam casting, coated sand casting, water glass sand casting, resin sand casting, and precision casting, while also being efficiently applied to polishing and cleaning processes for copper and aluminum castings, providing a one-stop solution for various casting processing needs.
