Electropolishing in Anodizing

Electropolishing is a treatment of aluminum using electric current in a chemical solution. The chemicals solution can be different for more detail can see on Electropolishing of Aluminum. Electropolishing is make the surface of aluminum is open, the pore of oxide film that already stay on the surface of aluminum oxide will remove and open. Oxide film surface can be formed in transportation or keeping in the store or just exposed to air. So the purpose of electropolishing is opening the oxide film surface on the aluminum surface.


To give more detail about electropolishing can see on the picture diagram how this process applied. Basically use electric current to open the surface of oxide film on aluminum surface. Here are the list detail process of electropolishing:

Bronze Product

Bronze often use in spare parts of Industry. Such as bearing and rolls. Bearings are also made largely from the 12% - 20% tin-copper alloys, and belts are the principal product made from copper-tin alloys with from 20% to 25% tin. Bronze also use to produce art product like for Gong in Indonesia. Because this metal have good sound and can hear in far distance. See Also: Bronze Application

Solubility of Chromic Acid

The kind of chromic acid are vary, there are technical uses and analytical purposes. Chromic acid is acidic chemicals with red color. Sometimes very strong red and sometimes pale red color. Chromic acid is poisonous chemicals if inhale of fume, and corrosive agent if dilute in water and contact with steel. Chromic acid concentration can be analyses in laboratory use certain method to analyses this substance. Chromic acid is produce in chrome industry, uses some high tech to produce this acid. Supplier will distribute this acid to all over the world. Chromic acid is dangerous if exposed to our body directly, so safety precaution and safety equipment should be use on handle this chemical. Chromic acid have carcinogenic characteristic if stay long time in our body. So people who work with this chemicals must read first MSDS of chromic acid. The formula of chromic acid is H2CrO4 and H2Cr2O7 each type of this formula have different characteristic on application. Some product purpose sh...

Bronze Alloy

The bronze alloy is among the oldest artificially produced alloys. The bronze age was coined by archaeologists to characterize the period following the neolithic when weapons and tools began to be constructed of bronze. Bronze have been is made by copper metal as base metal and mixed with tin and can be mixed with a little of zinc and phosphorous elements. See Also: Chromic Acid Quality
