Magnatuff is the result of extensive and intensive work done over the years in our R&D Department, both in terms of material and manufacturing systems - with the help of modern technology. This effort has resulted in making Magnatuff a product with consistent characteristics of high mechanical strength , uniform magnetic properties and close dimensional tolerances to meet with requirements of international standard.
