How to deal with aluminum alloy renovation

Hello, I'm glad to answer your question. Aluminum alloy has low density, but its strength is relatively high, close to or higher than that of high-quality steel. Good plasticity, can be processed into various profiles, and has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. Aluminum alloy belongs to non-ferrous metals. There are many polishing methods for metal renovation, but only mechanical polishing, chemical polishing and electrochemical polishing are widely used in industrial production. Some of the remaining polishing methods belong to or derive from these three methods, and some can only be applied to special materials or special processing needs. Let's briefly introduce the main polishing methods and choose the one you think is the most cost-effective.

1. Mechanical polishing, one is manual mechanical polishing, and the traditional method is to install polishing wheels. The other is belt polishing, which is a polishing method that puts the polished workpiece on the polishing belt with abrasive to achieve polishing effect.

2. Chemical polishing, that is, the workpiece is immersed in a chemical solution. Due to chemical etching, the micro-convex part of the surface is dissolved first than the concave part, thus achieving the purpose of leveling and polishing. Guangzhou Yishun Chemical Co., Ltd. has several chemical polishing agents for copper, such as beryllium copper polishing agent, brass polishing agent, red copper polishing agent and polishing agent.

3. Electrochemical polishing, that is, electrolytic polishing, is similar to chemical polishing in principle, and it also produces smoothness by selectively dissolving tiny protrusions on the surface of parts. In this method, a workpiece is put into a prepared electrolyte, the workpiece is used as an anode, and a material with good corrosion resistance and conductivity is used as an auxiliary cathode, and anodic electrolysis occurs on the surface of the workpiece after electrification. According to the principle of tip discharge, the tiny protruding parts on the surface of the workpiece are dissolved first.

I hope it helps you.
