In hardware selection, the choice of materials and application areas is very important. The following are some common materials and their application areas:

Metal materials:

Aluminum: light weight, high strength, widely used in aerospace, automobiles and electronic equipment housings.

Copper: excellent conductivity, often used in cables, electronic components and radiators.

Steel: high strength, wear resistance, often used in construction, machinery manufacturing and tools.

Plastic materials:

Polycarbonate (PC): high transparency, impact resistance, often used in electronic equipment housings and optical components.

Polypropylene (PP): good chemical resistance, light weight, widely used in automotive parts and household products.

Polyester (PET): excellent heat resistance and strength, often used in packaging and fiber products.

Ceramic materials:

Alumina: high hardness, wear resistance, often used in cutting tools and electronic insulators.

Silicon nitride: excellent heat resistance and oxidation resistance, often used in high temperature applications and mechanical parts.

Composite materials:

Carbon fiber composites: light weight, high strength, widely used in aerospace, sports equipment and high-performance automobiles.

Glass fiber composites: corrosion resistance, often used in construction, ships and wind turbine blades.

When selecting hardware, the material needs to be determined based on the specific application to ensure that its performance, cost and durability meet the requirements.
