The common materials for computer case shells include metal, plastic, acrylic and fiberglass, etc. The following is an introduction to their characteristics:

Metal material

Steel plate

Galvanized steel sheets: including hot-dip galvanized (SGCC) and electroplated galvanized (SECC). SGCC features acid resistance, rust prevention, corrosion resistance, long service life, light weight and other characteristics. Its surface is relatively bright and uniform in granular form. SECC has a better gloss, which is conducive to stamping. The galvanized layer is thick and uniform, less prone to rust and scratches. It has a strong adsorption capacity for electromagnetic radiation, especially low-frequency electromagnetic waves, and can effectively protect against electromagnetic radiation

The material of the computer case for digital products is galvanized steel plate

Cold-rolled steel plate (SPCC) : It belongs to the common cold-rolled carbon steel thin plate and strip, with relatively high strength. However, its surface is rough and not aesthetically pleasing. Most of them need to be sprayed, and they are very prone to rust when not sprayed. Nevertheless, it retains the good processability of cold-rolled plates and is widely used in cost-effective computer cases.

Aluminum alloy: It is lightweight, has good mechanical properties, is easy to process, has high heat dissipation, and has a fashionable and high-quality appearance. It is usually used in mid-to-high-end cases. Generally, aluminum alloy chassis have a sturdy structure and an attractive appearance, but they are relatively expensive. Moreover, their surfaces are prone to scratches and they are vulnerable to contact with acidic liquids.

Stainless steel: It has extremely high corrosion resistance and strength, can withstand significant external impacts, and is durable. However, it is relatively heavy and costly. Generally, it is less used in ordinary computer cases and is commonly found in some special cases with extremely high requirements for corrosion resistance and sturdiness.

Plastic material 1

ABS plastic: It has good mechanical properties, is impact-resistant, highly resilient, non-toxic, and does not fade easily. It can maintain its appearance color for a long time and has a relatively low cost. It is generally used in the non-structural parts of high-end cases and the structural parts of low-end cases, such as the front panel of the case.

HIPS plastic: Low cost, but poor performance, generally used in low-end cases.

PC plastic: Good performance, high price, mainly used in the structural parts of high-end computer cases.

Acrylic material 5

Its chemical name is polymethyl methacrylate. It has good transparency, chemical stability and weather resistance, is easy to dye and process, and has a beautiful appearance. It is often used in the side transparent part of the computer case, allowing users to directly see the hardware inside the case, but it is relatively brittle and prone to scratches.

Glass fiber material

It has good mechanical strength and insulation performance, and is often used to make computer case shells. It can effectively prevent electromagnetic radiation and is relatively light in weight. However, its appearance is not as beautiful as that of metal and acrylic materials, and the processing difficulty is also relatively high.

Tempered glass material 5

It has stronger light transmittance and better wear resistance than acrylic. It can effectively stabilize the machine body and prevent resonance of the chassis. However, there is a chance of self-explosion, the cost is relatively high, and it is usually only used in some high-end cases.
