半導體隔熱金屬板噴砂用棕剛玉F80

一級棕剛玉94-95%主要成分是Al2O3，次要成分是TiO2, SiO2，Fe2O3等。其主要優點是磨削力強，韌性高，硬度高，適合研磨大多數金屬和非金屬材料。一級棕剛玉選用優質棕剛玉塊料，經過破碎、制砂、篩分、磁選等工藝流程，得到不同型號的棕剛玉砂。一級棕剛玉砂根據粒度不同，氧化鋁純度也不同，一般情況下越細的粒度純度越低。

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.

半導體隔熱金屬板噴砂用棕剛玉F80的特點：

1. 硬度高，磨削力強，比天然金剛砂的磨削性能優越。

2. 韌性高，抗彎折能力強。棕剛玉的韌性比白剛玉略高一些，自銳性比白剛玉略低一些。

3. 經過磁選后的棕剛玉Fe2O3含量和磁性物含量都很低。

4. 棕剛玉的耐火性能好，在研磨過程產生的高溫狀態下，磨削性能依然很好。

5. 一級棕剛玉耐用度高，可循環使用。噴砂過程不粉化、碎屑少。

6. 棕剛玉粒度齊全，市場規模大，用戶可以根據實際要求隨意選擇粒度。

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.
