Aluminum circle
Aluminum circles or rods have the form of a continuous metal profile of a circular section with a certain diameter (the outer one is a pipe with a filled middle). Technical and physical properties directly depend on the processing method, as well as the composition of the starting material. Regarding the characteristics of the aluminum circle-rod, the following should be said:
• high electrical conductivity, which has a positive effect when welding;
• compared to other metals, it is characterized by low weight;(//tractor-service.com)
• has stable physical characteristics at temperature changes;
• characterized by a long service life;
• easily processed due to the high plasticity of the metal.
It is also worth noting that the circle is made of aluminum - a metal that does not have toxic properties and does not contain harmful components. It also has resistance to the negative effects of wet or aggressive environments.
