SX-ALZr10
Main features
1.This product will produce a number of ZrAl3 high melting point fine grains dispersively distributed. While solidifying. They will act as external crystal nucleus to fine grain structure so as to fine grain structure so as to enhance intensity and plasticity of aluminium material or casting and improve comprehensive mechanical performance.
2 .This product is white block metal with 250g for each. It has smooth surface without obvious visible slag holes.
3.Low adding temperature and low consumption for zirconium element.
Purpose
It is used for adding of zirconium element or grain thinning in aluminium alloy melting.
