Distinguishing the advantages and disadvantages of metallographic polishing cloths, experienced metallographists are experts in selecting high-quality and user-friendly polishing cloths. The method of pulse detection metallography is simple and easy to learn, and I will share it with you.


Look, touch, and use!


From the appearance, the surface texture of the fabric is uniform, flat, and dense; It feels textured to the touch; Long term use, water resistant, tear resistant, non curling, non staining, non shedding, This metallographic polishing cloth can be judged as of good quality.


Simply saying this is not specific enough. Below, the editor will provide a detailed explanation.

Metallographic polishing cloth can be divided into three categories: coarse polishing cloth, medium polishing cloth, and fine polishing cloth. Taking QMAXIS metallographic polishing cloth imported from the United States as an example, explain it one by one.

Coarse polishing metallographic polishing cloth


There are three types of materials available


1. Flat polyester fiber nylon material PlanCloth metallographic polishing cloth, gray white, plain weave, smooth and delicate, wear-resistant, and tear resistant. Compatible with 6µ Diamond polishing fluid of m and above is used for rough polishing of iron base, Thermal spraying metal coatings and hard materials.


2. Synthetic non-woven fabric material PerfoCloth metallographic polishing cloth, milky yellow, with holes, hard metallographic polishing cloth, good flatness, fine and dense small holes arranged neatly, wear-resistant, and tear resistant. Compatible with 6µ Diamond polishing fluids of m and above are used for rough polishing of materials such as ceramics, carbides, petrography, hard alloys, glass, and metals.


3. NylonCloth metallographic polishing cloth made of velvet free nylon fabric, orange yellow color, twill weave, flat and dense, non dyeing, wear-resistant, and tear resistant. Compatible with 6µ Diamond polishing fluids of m and above are used for rough polishing of materials such as iron-based, sintered carbides, and cast iron.

Medium polishing metallographic polishing cloth


There are three types of materials available


1. Synthetic compression non-woven fabric material DuraCloth metallographic polishing cloth, lint free, hard, yellow gray, good flatness, wear resistance, and tear resistance. Compatible with 9µ Diamond, Al2O3, SiO2 polishing solutions of m and below are used for medium polishing of Ferrous metals, non-ferrous metals, electronic packaging, printed circuit boards, Thermal spraying coatings, cast iron, ceramics, minerals, composites, plastics and other materials.


2. SatinCloth metallographic polishing cloth made of synthetic silk and natural silk materials, without velvet, light gray, with uniform and clear woven texture, good flatness, no snagging, wear resistance, and tear resistance. Compatible with 9µ Diamond, Al2O3, SiO2 polishing solutions of m and below are used for medium polishing of Ferrous metals, nonferrous metals, petrography, ceramics, coatings and other materials.


3. Pure silk material SilkCloth metallographic polishing cloth, velvet free, blue gray, woven texture is also very uniform and clear, with good flatness, no snagging, wear resistance, tear resistance, and no dyeing. Compatible with 9µ M-1µ M diamond polishing fluid, polishing paste, liquid polishing wax and other polishing media are used for medium polishing of Ferrous metals, non-ferrous metals, microelectronics, coatings and rock materials.

Fine polishing metallographic polishing cloth


There are four types of materials in total


1. Artificial fiber material MicroMet metallographic polishing cloth, brown, woven with long velvet and cotton backing, thick and dense, with good flatness, no shedding, no dyeing, and wear-resistant. Compatible with 3µ Diamond, Al2O3, and SiO2 polishing fluids of m and below are used for fine polishing of all materials.


2. Artificial velvet material VelCloth metallographic polishing cloth, gray green, short velvet, soft and dense, with good flatness, no shedding, no dyeing, and wear resistance. Compatible with 1µ Al2O3 and SiO2 polishing fluids of m and below are used for fine polishing of soft metals and electronic packaging materials;


3. Soft fabric FlocCloth metallographic polishing cloth, purple, plush, soft and fine, with good flatness, no shedding, no dyeing, wear-resistant, and tear resistant. Compatible with 3µ Diamond, Al2O3, SiO2 polishing solutions with a diameter of m or less are used for fine polishing of Ferrous metals, non-ferrous metals, sintered carbide and other materials. It can also be used in conjunction with aluminum oxide polishing powder for manual polishing of all materials, as well as fine polishing of unmounted specimens.


4. ChemoCloth, a chemically resistant synthetic fabric with metallographic polishing, is black, lint free, thick and dense, with good wear resistance, smoothness, non staining, and tear resistance. Compatible with 1µ Al2O3 and SiO2 polishing liquids of m and below are used for fine polishing of materials such as titanium alloys, stainless steel, lead&tin solder, electronic packaging, soft non-ferrous metals, and plastics.


Based on the above understanding, I believe you have mastered the method of distinguishing the advantages and disadvantages of metallographic polishing cloth, and can easily and quickly select the product you want from numerous similar products. If you encounter problems, you can also contact a pulse detection engineer to help you solve them!
