With the development of the LED flashlight industry, the design of the flashlight shell and the application of materials have also received great attention.

According to the flashlight shell material to distinguish, the LED flashlight can be divided into plastic flashlight and metal flashlight, and metal flashlight can be divided into aluminum, copper, titanium, stainless steel and so on. Now let’s talk about difference between the plastic case of the flashlight and the metal case of the LED flashlight.

Plastic:

Advantages: light weight, mold can be used to manufacture, low cost, easy or no surface treatment; the shell has excellent corrosion resistance, very suitable for diving applications.

Disadvantages: heat dissipation is very poor and even almost not good heat dissipation, not suitable for high-power flashlight use.

Now in addition to some low-end daily flashlight will do, professional flashlight basically excluded this material.

Metal:

Advantages: excellent thermo plasticity, corrosion resistance, high strength, good heat dissipation, and can withstand higher temperature deformation; can use CNC manufacturing complex structure. 

Disadvantages: high cost of materials and processing, heavy weight, generally need surface treatment.

 Common metal materials for flashlight brief introduction:

Aluminum: Aluminum alloy is the most commonly used flashlight shell material

Advantages: easy polishing, not easy to rust, light weight, good plasticity, processing is relatively easy, surface anodic plating can be obtained after good wear resistance and color.

Disadvantages: low hardness, fear of impact, easy deformation.

Copper: It is mostly used to make laser torches or limited edition torches

Advantages: with excellent heat dissipation performance, good ductility, low resistivity, is a very durable metal shell material, can be repeatedly recycled without damaging its mechanical properties.

Disadvantages: heavy, easy oxidation, surface treatment is more difficult, it is difficult to get high hardness, generally to electroplating, painting or paint-based.

Our company is professional in LED flashlight; we produce metal flashlight and plastic flashlight with different grades.
