Characteristics and applications of aluminum alloy composite materials

The characteristics of aluminum alloy composite materials include low density, high strength and modulus, small thermal expansion coefficient, and other characteristics such as high temperature resistance, high thermal conductivity, high electrical conductivity, and non-flammability, so they can be used in the aerospace industry and the automotive industry.

Aluminum alloy composite materials, commonly used aluminum alloys include industrial pure aluminum, 2014, 2024, 2009, 6061, 6013, 7075, 7475, 7079, 8009.

Commonly used reinforcements include boron fiber, carbon fiber, graphite fiber, silicon carbide fiber alumina fiber, aramid fiber, tungsten wire, steel wire, these particles and whiskers.

The reinforcement used in aluminum alloy composite materials should have the following characteristics: high strength, large film volume, heat resistance, wear resistance, corrosion resistance, small expansion coefficient, good thermal conductivity, good electrical conductivity, and wettability and chemical solubility with aluminum alloy.

Aluminum alloy composite materials can be used in aerospace antennas.

Gearbox, push rod, landing gear, pedals of aircraft helicopters.

The engine components, push rods, frames, and pistons of automobiles are mainly due to the light weight, rigidity, strength, and heat resistance of aluminum alloy composite materials.

Aluminum alloy composites are used in medical applications such as prostheses, wheelchairs, and orthopedic products. They are lightweight, rigid, and strong.

Aluminum alloy composites can also be used in sports equipment, such as tennis rackets, ski poles, fishing rods, golf clubs, bicycle frames, and motorcycle frames, mainly because of their light weight, rigidity, and flexibility.
