Heavy metal
Generally, the density is above 4.5g/cm3, such as copper, lead, zinc, etc.;
Light metal
Low density (0.53 ~ 4.5g / cm3), chemically active, such as aluminum, magnesium and so on.
Precious metal
The content of the crust is small, the extraction is difficult, the price is high, the density is large, and the chemical properties are stable, such as gold, silver, platinum, etc.;
Rare metal
Such as tungsten, molybdenum, niobium, lithium, antimony, uranium and so on.
Non-ferrous metals refer to all metals except iron, chromium and manganese. In 1958, China included iron, chromium and manganese as ferrous metals; and 64 metals other than iron, chromium and manganese were included in non-ferrous metals. The 64 non-ferrous metals include: aluminum, magnesium, potassium, sodium, calcium, strontium, barium, copper, lead, zinc, tin, cobalt, nickel, strontium, mercury, cadmium, antimony, gold, silver, platinum, rhodium, iridium. , palladium, rhodium, iridium, ruthenium, lithium, osmium, iridium, titanium, zirconium, hafnium, vanadium, niobium, tantalum, tungsten, molybdenum, gallium, indium, lanthanum, cerium, lanthanum, cerium, lanthanum, cerium, lanthanum, cerium , é“•, é’†, 铽, é•, é’¬, é“’, é“¥, 镱, é•¥, é’ª, é’‡, silicon, boron, selenium, tellurium, arsenic, antimony.
Mini Flap Disc
flap discs are widely used in automobiles, stainless steel products, metal products, glass manufacturing and other industries, and have special effects on welds, solder joints, flash, rust removal and surface polishing. The reason why the Flap Disc is so widely used is because it has five advantages that cannot be ignored:
1. The flap disc blades have high hardness, high strength and strong grinding ability during use.
2. The flap disc has low noise, low vibration and long service life during use.
3. The flap disc has strong wear resistance and long service life.
4. It is not easy to generate heat and burn parts during use.
5. The use of flap disc can improve work efficiency.
The related abrasive products we can supply is Flap Disc Adhesive, Flap Wheels , Sanding Belt , and Abrasive Machine such as Flap Disc Making Machine, Abrasive Belt Making Machine, Flap Wheel Machine , Polishing Machine , Sanding Disc Machine, if you have any needs about abrasive tools, please kindly feel free to contact us.
The flap disc blades can be used instead of resin Grinding Wheels and steel wire wheels. They have a good effect on rust removal, grinding and polishing. It is a good way to polish and remove rust. It is worth choosing!
Compared with the resin grinding wheel for fixed abrasives, it has the advantages of polishing and polishing at one time, shortening the operation time, saving the grinding cost, high efficiency, good heat dissipation, high grinding efficiency, reducing operator fatigue, increasing machine life, etc. It has strong elasticity, High tensile and bending strength and good grinding effect. The grinding speed is fast, the effect is good, and the noise during grinding is low. It is suitable for various industries or fields of manufacturing such as major metal parts factories and machinery factories. Good weather resistance, salt spray resistance and heat resistance, suitable for use in different regions.
