Brown corundum, also known as brown fused alumina, is widely used in various applications such as sandblasting, polishing, and grinding due to its excellent hardness, toughness, and chemical stability.
1. Consider the Purity and Grain Size
The purity and grain size of brown corundum are two essential factors that determine its performance and suitability for different applications. Generally, a higher purity level results in better performance, durability, and abrasive power. The grain size affects the cutting speed, aggressiveness, and smoothness of the corundum. Depending on your requirements, you can choose from a wide range of grain sizes, from coarse to fine.
2. Check the Chemical Composition and Physical Properties
Brown corundum is made of aluminum oxide and other minerals, which can affect its hardness, refractoriness, thermal conductivity, and color. You should check the chemical composition and physical properties of the corundum to ensure that they meet your requirements and the relevant industry standards. For example, if you need corundum for sandblasting, you should choose a type that has a high hardness and low friability.
3. Consider the Packaging and Transportation
When selecting brown corundum, you should also consider the packaging and transportation options offered by the supplier. The corundum should be packed in a sturdy and moisture-proof container to avoid contamination and damage during storage and transportation. The supplier should also provide you with fast and reliable delivery options to ensure that you receive your order on time and in good condition.
