What is the use of oxygen free copper?

 　　The higher the purity of any copper product , the better its corrosion resistance, the higher its conductivity, and the less heat generated during conductivity. As the purest copper product, C101 oxygen free copper provides the best results for all copper products. 　　By removing almost all impurities, the metal structure of copper is almost uninterrupted, and by removing almost all oxygen, the oxidation of metal copper is significantly reduced, which further hinders performance. 　　Due to the high price of high-purity products, almost all uses of C101 oxygen free copper are highly specialized. This includes: 　　Excellent audio/video applications - Quality critical high-end audio/video applications will use copper wire made of C101 oxygen free copper. 　　The increase in conductivity of C101 oxygen free copper for large industrial transformers can reduce the diameter of the internal wiring in the transformer, thereby reducing the amount of copper used and the overall in...

The difference between stainless steel and galvanized steel

图片
 　　Without protection, ordinary carbon steel is still prone to rusting in most environments. Therefore, there are many ways to modify steel to prevent corrosion. Two popular solutions are to use stainless steel or galvanized steel. Although both types of steel can resist rust and corrosion, there are important differences between them that should be understood. 　　What is stainless steel? 　　Stainless steel can resist corrosion because its chemical composition contains additional alloying elements. Although ordinary carbon steel is mainly composed of iron and carbon, stainless steel adds a large amount of chromium to help it resist corrosion. Chromium, sometimes with other alloying elements, is added to stainless steel during the initial melting process and then forms any specific shape. 　　What is galvanized steel? 　　Galvanized steel is a type of steel coated with a layer of zinc, which helps prevent rusting of the underlying steel. This layer is usually very thin, us...

Various stages of aluminum extrusion process

 　　1. The mold is cast with the required cross-sectional shape. 　　2. Heat the aluminum billet in the furnace until it reaches 750-925 º F. At this point, aluminum becomes a soft solid. 　　3. Lubrication, known as smut, is applied to steel billets and plungers. Black ear disease is essential as it ensures that the billet and plunger do not stick together. 　　4. The plunger applies pressure to the blank and pushes it through the mold. During this process, liquid nitrogen is used to cool the mold. Cooling can prevent the formation of unwanted oxides and extend the length of the mold. 　　5. Extruded aluminum comes out of the mold and has the same shape as the mold opening. The extrusion is pulled onto the cooling table, where it is exposed to air, water, or a mixture of both (depending on the final mechanical requirements of the metal). 　　Next is the stretcher. This can correct any twisting that may occur and straighten the metal. Improved hardness and strength during the s...
