How to choose the material of the light?

Various Material Characteristics, Pros and Cons


Stainless Steel Series
1. Stainless Steel 304

  • Characteristics: Offers good corrosion resistance, heat resistance, and workability, being the most common austenitic stainless steel used in a wide range of domestic and light industrial applications.
  • Pros: Relatively affordable, easy to process and weld, extensively used in kitchenware and architectural decoration.
  • Cons: Less resistant to corrosion in saltwater or chloride environments compared to the 316 series.

2. Stainless Steel 316

  • Characteristics: Enhanced with molybdenum addition, improving resistance to chloride ion corrosion, particularly suited for marine environments and chemical exposure.
  • Pros: Ideal for marine applications and chemical processing industries, offering longer service life.
  • Cons: Higher cost than 304 stainless steel.

3. Stainless Steel 316L

  • Characteristics: A low-carbon version of 316, reducing the risk of intergranular corrosion after welding.
  • Pros: Improved welding properties, suitable for applications requiring strict corrosion resistance and frequent welding, such as medical equipment and subsea pipelines.
  • Cons: Pricier than regular 316 stainless steel.

4. Stainless Steel 2205 (Duplex Stainless Steel)

  • Characteristics: Combines properties of austenitic and ferritic stainless steels, offering high strength and excellent resistance to stress corrosion cracking.
  • Pros: Suited for high-pressure, highly corrosive environments like oil & gas, chemical processing equipment.
  • Cons: More challenging to process and generally more expensive.



Copper Alloys
5. Brass

  • Characteristics: Comprised mainly of copper and zinc, it possesses good conductivity and corrosion resistance with an aesthetically pleasing appearance.
  • Pros: Easily worked, commonly used for plumbing, valves, and decorative items.
  • Cons: Prone to corrosion in saltwater environments and has lower strength and hardness compared to bronze.

6. Bronze

  • Characteristics: A copper-tin (and other elements) alloy, characterized by high hardness, wear resistance, and better corrosion resistance than brass.
  • Pros: Suitable for bearings, maritime hardware, and sculptures, especially excelling in seawater environments.
  • Cons: More costly and harder to machine than brass.


Aluminum Alloys
7. Anodized Aluminum

  • Characteristics: Through anodization, a protective layer is formed on the surface of aluminum, enhancing corrosion resistance and allowing coloration.
  • Pros: Lightweight, high strength, aesthetically pleasing, widely applied in building facades, aircraft, and electronic device casings.
  • Cons: Once scratched, the exposed area is more susceptible to corrosion despite improved overall corrosion resistance.
8. Electroplated Aluminum
  • Characteristics: A layer of metal (e.g., zinc, nickel) is deposited on the aluminum surface through electroplating, augmenting surface hardness, corrosion resistance, or aesthetic appeal.
  • Pros: Provides additional protection and aesthetic enhancements for products requiring high surface quality.
  • Cons: The plating process may pose environmental concerns, and it is generally costlier, potentially affecting the inherent ductility of aluminum.
The selection of each material should be based on its specific performance advantages and the requirements of the application environment.
