As an electrochemical technology, anodizing is used to form decorative, durable and corrosion resistant anodized surfaces on metal surfaces.
The anodizing process includes immersing aluminum in acid electrolyte solution to make the current pass through the medium.
It is not painted like paint or electroplating, but it is completely built into the aluminum base, so it will not crack or peel off.
Aluminum completely changed the metal world in the 1920s, providing advantages such as light weight, high strength, manufacturing versatility and durability.
Anodic oxidation treatment helps to make aluminum one of the most popular and widely used materials in hundreds of consumer, commercial and industrial product manufacturing.
The first and most important step in the history of aluminum is the invention of anodic oxidation, which forms a very hard and continuous aluminum oxide surface on the aluminum surface.
Anodized aluminum has changed the computer hardware structure, improved the satellite protection against bad weather, and formed modern computing by protecting spacecraft from the harsh impact of spacecraft.
Is anodized aluminum likely to deteriorate?
This kind of environmental corrosion can be reduced by anodizing the metal surface, but it cannot be completely stopped. Anodizing will generate a thin aluminum layer that will wear over time. According to the thickness and quality of anodizing, the surface should last for 10-20 years.
How do you know that aluminum is anodized?
Measuring the conductivity of the surface with a digital multimeter is a typical method to check whether the aluminum parts are anodized. If the parts are not anodized, the possibility of conductivity is high and the resistance is low.
Is anodized aluminum toxic?
It is non-toxic. The anodic oxidation coating will not be damaged due to overheating. The anodized surface can withstand the melting point of aluminum(1221 ° F) at high temperatures. The hard anodic oxidation makes the surface of the cooker very smooth, with almost no holes.
How to clean anodized aluminum?
Drop a drop or two of hot dishwasher into the cup. Wipe aluminum with a grinding sponge soaked in soapy water. Many harsh cleaning chemicals react with aluminum, so abrasives and mild cleaning solutions are required.
How do you know whether the metal is aluminum or tin?
If the metal is suspected of aluminum, please conduct the magnet test again and confirm again. Aluminum and tin may be mistaken for each other, but they will attach to the magnet instead of aluminum. The color of tin is also similar to aluminum. Although its appearance is a little dark.
Interesting Fact: If you want to know whether the trash can is tin or aluminum?
This is a tin can, but Hormel Foods is located in Austin, Minnesota. In July 1998, it began to convert the famous SPAM ® production line from three piece aluminum cans to two piece aluminum cans.
If you want to know why they become aluminum alloy?
Tin cylinders are lighter but more durable. Aluminum cans are lighter than tin cans, but tin cans are more durable. In terms of recycling, aluminum production has low energy consumption and can be easily recycled in the landfill, so it can be recycled in a more environmentally friendly way than other metals.
