FAQ:  Is Anodizing Safe?

Is Anodizing Safe?: Environmentally Friendly Technology, No Harmful or Dangerous By-Products, Non-Toxic Finish, Heat Resistant, Recycled By-Products, Safe Work Environment


The unique anodized finish of Superior's comprehensive range of aluminum anodizing services is only one of the properties that make it a desirable finishing process. Anodizing is the perfect solution when health and environmental concerns arise.

When it comes to coatings, anodizing is a safe and environmentally friendly  technology, as clean a process as is available today. Anodizing is an acceleration of a natural oxidation process. It does not produce harmful or dangerous by-products, and will not damage human health or the environment. Other benefits include:

  • An anodized finish will not break down or decompose
  • The finish is non-toxic
  • It is heat-resistant to 1,221 f, (the melting point of aluminum)
  • Anodizing uses simple water-based chemicals that can be treated easily and that release no harmful by-products
  • The liquid by-products are recycled and returned to the process
  • Solid by-products can be separated for other uses, such as:
    • Aluminum manufacturing
    • Baking powder
    • Cosmetics
    • Newsprint
    • Fertilizer
  • Anodizing's primary by-products are harmless aluminum hydroxide and aluminum sulfate can be used as filters in the sewage treatment process of municipal sewage treatment plants.

Anodizing plants are safe, well ventilated, worker-friendly environments. Workers are well trained in the use of anodic materials and processes. In general, to ensure worker safety employees only need to wear a minimum of special protective clothing. In most cases, only a minimum of safety equipment is required.
