Metallographic consumables are the general term for metallographic supplies such as sandpaper, polishing powder, cold gel, polishing fluid, cutting discs, inlay materials, and plastic molds. Some metallographic consumables are introduced below:
1. Metallographic sandpaper: Metallographic sandpaper is suitable for grinding wet or dry (W/D) materials, with diversified styles, such as strips, rounds, long and narrow, rolls, large pieces, etc., and it is very durable and will not be affected by It loosens when it comes into contact with oil, alcohol, or water. The bottom of round and roll sandpaper has adhesiveness (PSA). Silicon carbide (SiC) grinding sandpaper is suitable for rough and fine grinding/polishing. Alumina (Al2O3) grinding sandpaper is suitable for rough and fine grinding. The round sandpaper models are P60, P120, P180, P280, P400, P800, P1200, P2400, P4000.
2. Metallographic polishing powder: alumina (Al2O3) and silicon carbide (SiC) polishing powders are suitable for fine grinding and rough polishing. Magnesium oxide (MgO) polishing powder is suitable for finely polished aluminum alloys, magnesium alloys and magnesium-containing materials. Iron oxide (Fe2O3) polishing powder is suitable for polishing soft ores, glass, gems and soft metals. Chromium oxide (Cr2O3) polishing powder is suitable for alumina grinding materials. When using polishing powder, it must be mixed with distilled water.
3. Metallographic cold gel: coagulation takes 5 minutes to 8 hours, including gel cup (soft body, hard body), coagulation powder, stirring rod, sample holder (such as: stainless steel sample holder, O-shaped plastic sample holder, P Type plastic sample holder, circuit board sample holder, polishing angle softening clip, sample fixing clip), filler powder, mold release agent, epoxy resin, acrylic resin, acrylic resin (advanced type), sample hard powder, scale Paper cups. Epoxy resin has high permeability, low expansion, resistance to chemicals and other properties, which can fix samples.
4. Polishing liquid containing diamond particles: For ordinary polishing, the polishing liquid containing diamond particles should be used together with polishing powder or polishing paste. Available in 0.1um, 0.25um, 1um, 3um, 6um, 9um, 5um, 30um, 45um. The metallographic polishing liquid can make the sample polish better. Al2O3 SiO2 (0.05um) polishing liquid is suitable for final polishing of cold gel samples, especially suitable for soft materials, mixtures and ceramics. SiO2 (0.05um) polishing liquid has the characteristics of high pH without damaging the sample, and is suitable for final polishing of electronic parts. CeO (1.0um) is suitable for soft materials for final polishing. SiO2 is suitable for three-dimensional materials for final polishing.
5. Metallographic cutting discs: cutting discs are divided into ordinary cutting discs and cutting discs containing diamond particles. The diameters of ordinary cutting discs are 152mm, 178mm, 229mm, 254mm, 305mm and 356mm. Alumina (Al2O3) cutting discs are suitable for iron-containing alloys and steel materials; silicon carbide (SiC) cutting discs are suitable for medium hardness and softer and non-ferrous metals, strong and non-metallic mixtures, titanium alloys and ceramics Industry. The cutting discs containing diamond particles are divided into high-density and low-density. The diameters are 76mm, 102mm, 127mm, 152mm and 178mm. High-density cutting discs are often used to cut metals and ceramics; low-density cutting discs are suitable for cutting easily damaged materials (such as: ceramics, glass, carbides and other heat-resistant materials). Adding coolant or water during cutting can reduce cutting time and increase cutting accuracy.
