Extruded aluminium square tube is frequently used in the places where lightweight and corrosion resistance is important, such as framework, support columns, gates and fencing, handrails and protective barriers. In Otalum, we offer a wide range of square aluminium profiles with a variety of alloys, sizes and finishes. All of our square aluminium extrusions can also be cut to a specific size if the existing products cannot meet your requirement. Precise cutting to length and processing services are available with the fastest lead time.

Aluminium round tube or pipe is used in a lot of structural applications. It is also popular in the transportation industry (like bicycle frames) due to its lightweight. It is measured by initially taking the outside diameter and then the wall thickness. In Otalum, we offer a wide range of aluminium round tube/pipe with a variety of alloys, sizes and finishes. Moreover, all of our round aluminium tubes can also be cut to different sizes in case the existing products cannot meet your personal needs. As a professional aluminium extrusion factory, Otalum provides precise cutting to length and diverse processing services with the fastest lead time

Aluminium round bar is frequently used in the transportation, construction and aviation industries due to its excellent strength to weight ratio. In Otalum, we offer a wide range of aluminium round bars with a variety of alloys, sizes and finishes. Our solid aluminum round bar can also be cut to a specific size if the existing products cannot meet your requirement. Moreover, just like the customization services Otalum provides for all the other aluminum extrusions profiles, precise cutting to length and other processing services of aluminium hollow/solid round bars are also available with the fastest lead time.

Product Description Steelmaking Deoxidizer Ferrosilicon Alloy Product Description Ferro silicon alloy is composed of iron and silicon ferrosilicon alloy. Ferrosilicon is coke, scrap steel, quartz (or silica) as raw material, made of electric furnace smelting iron silicon alloy. Not only the chemical affinity between silicon and oxygen is very big, and the carbon content of high silicon ferrosilicon is very low. So high silicon ferrosilicon (or siliceous alloy) is in ferroalloy industry are frequently used in low-carbon ferroalloy production a reducing agent. Steelmaking Deoxidizer Ferrosilicon Alloy 0 Steelmaking Deoxidizer Ferrosilicon Alloy 1 Product Application 1. Ferrosilicon is often used as deoxidizer in steel- making. 2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non- ferrous metal, bearing steel, heat-resistant steels and electrician silicon- steel. 3. It can be used as a reductant in ferroalloy production and chemical industry. 4. In iron industry it can be used as inoculant and nodulizer.

Product Description Refractory Ferro Silicon Alloy S100-SI3N497​ Ferro Silicon Nitride For Refractory Material Lump Shape Product Description Silicon Nitride, a chemical formula Si3N4, is an important structural ceramic materials. It is a superhard material itself has lubricity and wear resistance for the crystal atoms; anti-oxidation at high temperatures. And it is also resistant to thermal shock, heated to above 1000 ℃ in the air, chilling sharply heating, and will not be cracked. Ferro Silicon Nitride Application Silicon Nitride is used as senior refractory materials, such as sic combination for SI3N4-SIC refractories for blast furnace body parts; combined with BN for SI3N4-BN material, split ring for the horizontal continuous casting. SI3N4-BN horizontal continuous casting separation ring is a fine structure of ceramic materials, uniform structure, high mechanical strength. Thermal shock resistance, will not be liquid steel and humid, in line with the process of Pente requirements.
