Product Details

Blasting grade chrome corundum/pink fused alumina/pink corundum grains 12#-220# to sale

Product Description

The toughness of pink fused alumina is higher than that of white fused alumina.For greater toughness machining materials,the processing efficiency is better than white fused alumina.Pink fused alumina is suitable for processing high toughness of hardened steel,alloy steel precision measuring instruments and other parts which require high toughness finish of the workpieces.

Advantages

1.High toughness,high hardness,good self-sharpening

2.Environmental protection,no pollution to the environment

3.Strong grinding ability, low heat generation and high efficiency.
