产品简介

一级棕刚玉94-95%主要成分是Al2O3，次要成分是TiO2, SiO2，Fe2O3等。其主要优点是磨削力强，韧性高，硬度高，适合研磨大多数金属和非金属材料。一级棕刚玉选用优质棕刚玉块料，经过破碎、制砂、筛分、磁选等工艺流程，得到不同型号的棕刚玉砂。一级棕刚玉砂根据粒度不同，氧化铝纯度也不同，一般情况下越细的粒度纯度越低。

Brown fused alumina grit is a basic abrasive grain for making abrasive tools and abrasive blasting. It is produced from natural bauxite mine by a fusing process. After fusing and melting at about 2000 centigrade, it turns to a kind of artificial brown fused alumina. The main chemical of brown fused alumina is Al2O3. So it also be called brown aluminum oxide.

With different milling technology, there are several types of brown fused alumina. They are available for different applications such as sandblasting, surface treatment,resin bonded abrasives, vitrified bonded abrasives,anti-skid materials,etc.The higher Al2O3 purity, the higher hardness and better grinding performance.

一级棕刚玉砂的特点：

1.硬度高，磨削力强，比天然金刚砂的磨削性能优越。

2.韧性高，抗弯折能力强。棕刚玉的韧性比白刚玉略高一些，自锐性比白刚玉略低一些。

3.经过磁选后的棕刚玉Fe2O3含量和磁性物含量都很低。

4.棕刚玉的耐火性能好，在研磨过程产生的高温状态下，磨削性能依然很好。

5.一级棕刚玉耐用度高，可循环使用。喷砂过程不粉化、碎屑少。

6.棕刚玉粒度齐全，市场规模大，用户可以根据实际要求随意选择粒度。

1.High hardness around Mohs 9.0.

2.High toughness which is a little higher than white fused alumina.

3.Good grinding ability.

4.A quality level with high Al2O3 purity and low TiO2 impurity.

5.Low Fe2O3 content with magnetic removal treatment.
