Electropolishing is a process known as reverse electroplating. It involves the electrolytic removal of metal flaws e.g. burrs and spikes, in a highly ionic solution using both an electrical potential and current. Although the most common method with which the process is employed is stainless steel, this is not the only method subjected to this finishing process. electropolishing on aluminum services are also available from many fabricating and finishing companies.
Why Employ Electropolishing?
Electropolishing is a finishing process. Companies use it to accomplish a number of things including achieving a high quality finish. Components that undergo this process emerge:
- Hygienically clean
- Free from various flaws including burrs
- Reflectivity
- Passivity
Yet, fabricators have other reasons why they choose electropolishing when it comes to aluminum.
Why Employ Aluminum Electropolishing?
Working with aluminum can be challenging when it comes to finishing off the surface of the metal. In the past, the most common means of smoothing and polishing the surface of this metal was bright dipping. Although effective, it is surrounded with various safety and health concerns. The byproducts for this process are toxic chemicals. In other words, while bright dipping does successfully remove the flaws and make the aluminum aesthetically pleasing, it can also endanger the health and even lives of those who perform the process.
To avoid such issues, anyone utilizing this method must make certain proper procedures are in place. Protocol must prevail. Protective devices such as fume hoods must be used and the aluminum content and temperature must be constantly checked. Alternatively, fabricators can use electropolishing on aluminum. Services of this type do not result in the release of toxic fume or require special safeguards for worker safety.
Advantages of Aluminum Electropolishing
Aluminum is a metal commonly employed in a variety of applications. In some instances, it has become as popular as stainless steel. Aluminum has gained favor because of its low cost, easy machinability and light weight. This method of preparation for metal offers advantages in several ways to both consumers and producers. These include:
- Removing the surface flaws and contaminants
- Increasing the lifetime of the component
- Improving surface and galvanic corrosion resistance
- Enhancing surface finish
- Makes it easier to cleaning
- Reducing product adhesion
- Deburring
- Decreasing susceptibility to cracking
- Reducing vulnerability to microbiological corrosion
Just as important, electropolishing of aluminum is also more environmentally friendly and safer than other methods.
Electropolishing on Aluminum Services
If aluminum components require finishing, fabricators can choose between two major processes. These are bright dipping and electropolishing. While both offer advantages, many companies rely on electropolishing on aluminum services to produce the results they want with greater safety and ease.
