The use of materials with low specific weight is an effective way of reducing the weight of structures. Aluminum alloys are among the most commonly used lightweight metallic materials as they offer a number of different interesting mechanical and thermal properties. Its outstanding properties are lightness its density is one-third that of iron, good electrical and thermal conductivity. It is a good reflector of light and a good radiator of energy. It is non-magnetic, it is resistant to atmosphere due to the formation of a protective oxide film. It has good tensile strength in the form of alloys. Aluminum parts are economical, light weight and attractive. Parts made from this metal are often less expensive because they can be machined in less time than many other metals such as steel and do not require additional finishes.
The use of Aluminum in automotive applications is expanding. The automobile manufacturers have been one of the leaders in recognizing the adaptability of Aluminum. Aluminum offers a lower- weight alternative to steel, potentially increasing the efficiency of vehicles. Aluminum is used in many vehicle components, but a few components account for the majority of the Aluminum now in use. Engines, transmissions, heat exchangers, wheels, chassis applications, suspension and steering.
The highest volume of Aluminum components in cars are castings, such as engine blocks, cylinder heads, wheels and special chassis parts. As automotive industry is searched for weight reduction and lower cost, aluminum Die casting provided ideal combination. The substitution of cast iron engine blocks continues, even for diesel engines. However, due to the high requirements on strength and durability, cast iron is still often being used. Significant progress in Aluminum alloy development and better process control and casting methods improved material properties and functional integration that enables Aluminum to meet the specific high requirements.
The Aluminum die casting provides benefits to manufacturer as well as to the customers. The Aluminum casting can allow the attainment of complex design this means that customers can easily order customized casting that will be for their production needs. Aluminum casting have good machinability and surface finish. Aluminum casting allows producers to manufacture the finished parts at a faster rate than other alloys material.
Where Star Machining Technology provides Flexible Quantities, High Strength, Less machining our goal is to minimize secondary machining, Low Cost, Fine surface finishing, Close Tolerance, High quality.
