Introduction

SHAPER Material Products

with good performance indicators.

Chemical Composition

The chemical composition is the main indicators to show the material's quality and performance. Higher purity and fewer impurities are based on advanced production technology.

Hardness

Usually ,abrasive material hardness is higher, the performance

of corrosion resistance and cutting machinability will be better.

Toughness

Abrasive material need has toughness, to make sure strong cutting force, also need has brittleness, to make sure strong

self-sharpening.

Hydrophilic

Hydrophilic is an important factor decide abrasive material's binding force and influence coated abrasives produce cost and performance.

Bulk density

Bulk density is an important technological parameter,abrasive grain's density ,shape and grit distribution are decisive factors for it.bulk density is closely related on abrasive tool's formability,

strength,porosity and influence grinding performance.

Shape

Shape of abrasive grain also is a very important performance. blocky shape(sphere) is more perfect, it influences toughness,bulk density and hydrophilic. Abrasive through advanced plastic and selection processing,could obviously increase the product form content such as blocky shape grains.

Product Description
