Cast Iron Supplier
Unibar 200 is a predominantly ferritic iron and the softest grade in the Unibar portfolio, offering exceptional machinability and excellent surface finish, but limited strength and wear resistance. Noise, vibration damping and thermal conductivity are excellent in this grade.
Unibar 250 is a pearlitic-ferritic iron that offers a good combination of strength and wear resistance over Unibar 200, while still possessing good machinability and an excellent surface finish. Due to the graphite structure in Unibar 250 noise and vibration damping along with thermal conductivity are excellent in this grade.
Our grey iron Unibar 300 is alloyed to achieve the specified properties, giving excellent wear resistance, strength and heat-treatment response compared to Unibar 200 and Unibar 250, while still possessing reasonable machinability and an excellent surface finish. Noise and vibration damping are good in this grade.
Unibar 350 is a special grade alloyed to achieve specified properties, gives excellent wear resistance and strength. Suitable for all heat-treatment applications, the pearlitic structure giving a better response compared to Unibar 200, 250 and 300, while still possessing reasonable machinability and producing a good surface finish after machining. Noise and vibration damping are good in this grade.
Our spheroidal iron Unibar 400-18LT offers superior machinability combined with good low-temperature impact, fatigue, electrical conductivity and magnetic permeability, along with an increased ductility over Unibar 400-15. Noise and vibration damping are good in this grade.
