What is a hard anodized aluminum?

Anodized aluminum is an aluminum that has been treated with sulfuric acid, while the solution passes through low -voltage current. The hard anodized aluminum was treated in a similar way, except that the electric current is significantly higher and the solution temperature is reduced to 32 ° F (0 ° C). Depending on the process, the solution may also contain oxalic acid. The process creates a material that is stronger, harder and smoother than aluminum that has not been anodized.

Although a number of different metals can be anodized, aluminum responds differently to the process. The aluminum anodization produces a thin coating that protects against rust, but some processes also produce a much stronger rust barrier. The final product has many different uses and is an important part of many cars and aircraft. Architects can use an anodized aluminum for external decorations and electronics manufacturers value it for their ability to insulate sensitive parts of electricity.

Automobile cars have long been the main fans of anodizedESU for aluminum. Although stainless steel provides some of the benefits of hard anodized aluminum, the steel is heavier and more expensive. Anodized products can withstand high temperatures and does not take electricity.

Professional chefs and chefs often prefer anodized pans for more than the ability of the material to withstand heat. Hard anodization creates a smooth surface that provides a non -stick surface even without the use of non -stick coatings. Fine foods can be prepared to relax easily and are more attractive. Cleaning hard anodized aluminum pans usually requires little effort, but should not be placed in the dishwasher.

Medical area is another area for adapting hard anodized aluminum for its needs. Prosthetics and artificial joints made of anodized aluminum are a strontr than those of conventional aluminum, yet the weight does not significantly increase. By using a hard anodized aluminum, Protet designers canIky to create devices that are more durable and operate smoothly. Implanted devices and joints made of anodized aluminum are more resistant to harmful blood effects, which can cause corroding these devices.

Manufacturers can easily add a dye during an anodly process to create different colors. The solution penetrates deep into the coating and carries the dye. As a result, the finished product resists fading. However, some colors are more resistant to disappearance than others, with certain shades of red and blue are more susceptible to fading and black, which are least likely to disappear. Without adding the dye, the color of the hard anodized aluminum moves from dark brown to dark gray.
