Sand Cast Aluminum (SDA) is a lightweight, strong material that is strong enough to be used for both indoor and outdoor products. The material has excellent thermal conductivity, as well as chemical, mechanical properties. It is resistant to alkali, salt and other chemicals, withstanding pressures of up to 1000 psi. It is also waterproof, with a degree of vapor resistance at lower temperatures. In addition to its excellent thermal and moisture resistance properties, it also has good corrosion and rust resistance.


The basic process of sand cast aluminum sand casting starts with the preparation of a mold in which the metal will be poured. In most cases, molds may be hand dug manually to fit the intended mold size. Once the mold is ready, it is left to cool, so as to induce gas-tightness. In some cases, special metal wedges are used to ensure proper formation.


There are many advantages to using this type of aluminum continuous casting products. For one, it provides an effective solution for making pipes and tubes. It is considered the best alternative to PVC pipes. Also, it can be cast in different sizes depending on the intended application, for example, tubes of different sizes for drinking water systems or heating pipes.


Another advantage of this metal is that it is easy to install, with almost no alteration to the structure of the pipe. Unlike other metals, it does not experience mechanical stresses when the pipe is under pressure or heat treatment. It can therefore be used for a wide range of applications, including high-tempered steel pipes. It is also capable of handling different pouring temperature, as well as corrosive agents.


This type of metal also has a number of disadvantages. First of all, this type of product tends to expand in size when exposed to heat and pressure, resulting in small gaps between the walls. When this happens, the mechanical properties of the product deteriorate. The chances of the metal's chemical reaction with the surroundings also increase, resulting in less resistance. In addition, the surface finishes of this product tend to be rough, and hence more susceptible to abrasions and cuts.


Another drawback of using this type of metal in making parts is that it tends to corrode when exposed to high-pressure aluminum die casting processes. It is therefore recommended that the metal parts used in high-pressure CNC machines should be carefully protected with high-grade die coatings. Additionally, the surfaces of the metal parts may rust due to ultraviolet light. Therefore, the timely care and preservation of these materials is essential.
