Metal refining is a technological process that aims to purify the mineral raw material from admixtures and impurities to obtain pure metal of high quality. It is an important stage in the metallurgical industry, as it allows obtaining metals with the right parameters and properties, which are...
Metalworking is a technological process that changes the size, shape and other characteristics of metal products. Various types of machining are used - casting, machining, electrical and heat treatment, welding. One of the oldest methods of metalworking Casting is the process of...
Scientists estimate that an aluminum can will decompose and poison the soil for at least 500 years. Fortunately, we have made great strides in recycling polluting materials. Today, aluminum is successfully recycled, and it is possible to make a new one from an old used aluminum can. What is...
Finishing aluminum with brushing is a very common practice. It allows you to give the surface a matte or sandblasted appearance. Brushing aluminum - what is the purpose? One of the advantages of brushed aluminum is that it can be used to make a wide range of items. The brushed finish is...
Aluminum is a very versatile metal and has a wide range of applications. Its surface can be smooth and shiny or but also satin-finished. What is aluminum satin finishing? Aluminum satinizing is a process that aims to produce a uniform, semi-gloss or opaque surface on surfaces or pieces of...
Why is aluminum harder to weld than ordinary steel or even alloy steel? It's all about the temperature difference required to melt the top oxide layer and weld the metal itself. The top layer has a melting point of 2044 degrees, while aluminum and its alloys have a melting point of 660°C...
Casting is the oldest metallurgical technique known to us. The first functional metal elements were accidentally refined copper from chalcopyrite and chalcocite rocks. The metal could be cast into ingots and given a useful shape. Aluminum casting is an extremely important method for producing...
