Common materials of construction for electronic enclosures are Acrylonitrile-butadiene-styrene (ABS), aluminum, polycarbonate, polystyrene, stainless steel, and steel.

ABS is a hard, rigid, thermoplastic polymer. It provides good chemical and creep resistance, and dimensional stability and is the most commonly available material.

Aluminum has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.

Polycarbonate is an amorphous material with excellent Impact Strength, clarity, and optical properties. It also can be molded to tight tolerances for products that need tight dimensional accuracy.

Stainless steel is chemical and corrosion resistant.

Enclosure can also be designed to shield against electromagnetic interference by coating it with EMI or RFI coatings. It can also be constructed of flame retardant material for applications that need to have a high degree of safety.
