Siliven New Material Co., Ltd.
Mental matrix composites
Equipped with integrated functions of temperature resistance, structural load-bearing and lightweight, the material has the
characteristics of low density, high tensile strength, high elastic modulus, and high heat resistance. The density of aluminum
matrix composites can reach 3.0g/cm3, which is over 30% lower than titanium alloy materials. The tensile strength is more than
850MPa, and the elastic modulus E is greater than 100GPa.

BXPA2 Aluminum Matrix Composite Material (T5)
It has high specific strength, specific stiffness, and shear strength, as well as good thermal stability, thermal conductivity, resistance to wear and corrosion, and excellent heat resistance and high-cycle fatigue strength. Its performance is as follows:
Studies have shown that in the BXPA2 series of materials, when the SiC fiber content is 30%, its flexural strength and tensile strength are 80% and 30% higher than those of superhard aluminum, respectively. It can withstand high temperatures of 400-450℃ (100-150℃ higher than aluminum alloys) and has better structural durability. In addition, due to its low density, BXPA2 is only 60% of titanium alloys. Therefore, in environments where the service temperature does not exceed 500℃, BXPA2 can replace some steel and titanium alloys for use in aircraft, missile structural components, and aerospace engine components, thereby achieving significant weight reduction. Thus, SiCf/Al will be the most promising type of composite material in the fields of aerospace, weapons and equipment, and civil transportation. Using BXPA2 series materials, we have currently developed products such as tail fins, heat-resistant cylinders, and aerospace engine casings.
