Which one is better for polishing, white alundum or brown aluminium oxide?
White alundum has a better polishing effect.
White alundum has a higher hardness and stronger wear resistance. It is suitable for high-precision and high-finish polishing needs. It can achieve excellent finish and is not easy to scratch. In contrast, although brown corundum also has a certain polishing effect, its hardness is lower. It is suitable for rough grinding and cutting operations, and the polishing effect is not as good as white corundum.
Specific performance of polishing effect
Finish : White has smaller polishing particles and can achieve higher finish. The surface is smooth and scratch-free.
Wear resistance : White alundum has better wear resistance and can maintain a stable polishing effect during long-term use.
Scope of application : White corundum is suitable for polishing high-precision and high-finish materials, such as bearings, tools, etc.
Cost and cost performance .
Although the price of white is higher, its excellent polishing effect and durability make it more cost-effective, and it can save costs in the long term.
Although brown corundum is cheaper, its polishing effect and wear resistance are not as good as white , so it may not be the best choice in high-demand polishing operations.
In summary, if high-quality and high-finish polishing effects are required, white alundum is a better choice; if there are high requirements on cost and low requirements on polishing effects, brown corundum can also be used as an alternative.
