Alumina suspension grinding and polishing fluid for metallographic sample preparation

Description

Product Introduction:

　When certain softer, tougher specimens require final polishing to achieve the desired results, an oxide‑based suspension polishing slurry should be used.

Technical Specifications:

Name	Description	Granularity	Packaging (bottle)
Aluminum oxide suspension Grinding and polishing fluid	The suspended polishing slurry is formulated with high-purity alumina micropowder, offering stable abrasive dispersion, uniform particle size, and no agglomeration. It has a neutral pH and is used for polishing a wide range of precision components as well as for metallographic section analysis. Usage: Use directly.	7 μm, 5 μm, 3 μm, 1 μm	500ml
		0.5 μm, 0.3 μm, 0.1 μm, 0.05 μm	500ml
	Aluminum sol is formulated with high-purity alumina fine powder, offering high abrasive hardness, strong grinding performance, and a pH of 8.5. It is used for the precision polishing of soft and medium-hard materials, including precious metals, ferrous alloys, carbides, low-melting-point alloys, printed circuit boards, and electronic components. Usage: Use in conjunction with polishing lubricant.	7 μm, 5 μm, 3 μm, 1 μm, 0.5 μm,	500ml
		0.05 μm	500ml
	Aluminum–silicon sol is formulated by combining high-purity alumina micropowder with silica gel, ensuring uniform dispersion of the abrasive particles and strong grinding performance. With a pH of 9, it is ideally suited for the final polishing of water‑sensitive materials, oxidation‑prone materials, minerals, and metal matrix composites. Usage: Use in conjunction with polishing lubricant.	0.05 μm	50
