MQP is a global leader in the development, manufacture and application process of grain refinement in aluminium alloys.
Our product, Optifine, is a highly efficient grain refiner produced in a state-of-the-art facility using our proprietary know-how. Quality assurance and development of Optifine products is carried out at our laboratory in Sweden and our Technology Center in the UK.
Optifine 3/1 was developed after 20 years of research, and improvement of grain refinement practices in the worlds leading casthouses.
By implementing Optifine in your process, grain refiner addition rates can be reduced by 70% whilst improving alloy micro-structure and still achieving the same grain size as using any other grain refiner. Now MQP is introducing Optifine 5/1 with a higher efficiency allowing addition rates to be reduced by 85% compared to standard grain refiners
Optifine has been used in regular production since 2010, it is now one of the most important consumable products in more than 34 major casthouses worldwide where producing high quality aluminium alloys with outstanding results is a priority. To date, more than 6,000t of Optifine, the equivalent of 18,000t of standard grain refiner, has been supplied to the Aluminium industry and casthouses are casting more than 6 million tons per year of Optifine grain refined Aluminium alloy products.
