Zirmax is a zirconium grain-refiner for magnesium-zirconium alloys containing nominally 33% zirconium micro-particles in a magnesium matrix. Zirmax is specially prepared to enable simple and effective grain refinement of the alloy by the foundry. Good grain refinement is essential in the production of high quality castings. Applications: Zirmax is a high performance grain refiner for use with Elektron Magnesium-Rare earth alloys such as Elektron® 21, ZE41A, EZ33A, WE43B or QE22A. Zirmax master alloy creates a super-fine equiaxial grain structure in the alloy which promotes high mechanical properties, improved castability and excellent casting integrity.
