Cheap Brown Aluminium Oxide Manufacturers Italy

Heat treatment is one of the thermal processes of metal materials, which is an important part of various mechanical manufacturing processes(brown aluminium oxide). Magnesium is a trace additive element, which can improve the room temperature strength of the alloy and improve the heat resistance strength below L50 ℃ - 250 ℃(white fused aluminum oxide 60 grit). Both iron and silicon are trace additive elements, and the mass fraction of iron and silicon is generally controlled below 0.3%.

However, the welding performance will be reduced after adding iron(white alumina). Therefore, the mass fraction of magnesium should be controlled, generally no more than 0.05%. After forging and heat treatment, when they are dispersed in the structure, the heat resistance of the alloy can be significantly improved(garnet suppliers). Therefore, the mass fraction of copper should be limited to less than 0.2%. But it is not good for the surface gloss of annealed materials.(cheap brown aluminium oxide manufacturers italy)


The addition of 0.5% - 1.2% Si into 8 forged aluminum can improve its room temperature strength, but decrease its heat resistance(black corundum). The addition of 0.02% - 0.1% Ti in No.7 forged aluminum can refine the as cast alloy grain, improve the forging process performance, and is beneficial to the heat resistance, and has little effect on the room temperature performance(brown corundum powder). Therefore, the alloy has good room temperature strength change and good heat resistance.


(cheap brown aluminium oxide manufacturers italy)It can improve the yield strength and impact toughness, reduce the brittle transition temperature, and is beneficial to the welding performance(garnet abrasive). Zinc is a kind of trace element, which can accelerate the diffusion of steel in aluminum. The mass fraction of zinc should be limited to less than 0.1%(white aluminum oxide 220 grit). Because the mass fraction of steel and magnesium in the alloy is lower than that of duralumin, the alloy is located in the two-phase region.


The process of heating metal products or parts to a higher temperature(black silicon carbide), holding a certain time, and then cooling slowly to obtain a structure close to the equilibrium state is called annealing. When the mass fraction of copper in the alloy is 0.05% - 0.5%, the tensile strength can be significantly increased, but the corrosion resistance of the alloy will be decreased(brown aluminum oxide 70 grit). It can also improve the weldability and weld plasticity of the alloy.(cheap brown aluminium oxide manufacturers italy)


The so-called heat treatment is to heat metal products or parts to a certain temperature(green silicon carbide), and stay at this temperature for a period of time, and then cool down to a certain temperature with appropriate cooling rate. Heat treatment changes the structure of the metal, so as to improve the properties of the metal, so as to meet the requirements of various uses(alumina abrasive). Various heat treatment processes used in modern industry are introduced as follows.


(cheap brown aluminium oxide manufacturers italy)Although the material selection is appropriate(pink corundum), without corresponding heat treatment process, it is impossible to meet all kinds of application requirements, and the potential capacity of materials is not exerted. When the mass fraction of zinc is less than 0.5%, it has no effect on the properties and corrosion resistance of the alloy(fused aluminum oxide). Considering the weldability of the alloy, the mass fraction of zinc should be limited to less than 0.2%.
