Non-ferrous metals are all metals other than iron and alloys that do not contain a significant amount of iron. Non-ferrous metals can be crushed or hammered into thin sheets without breaking, making them highly malleable and one of their main characteristics. Iron is generally present in non-ferrous alloys in quantities of less than 1% of the total weight. Compared with ferrous metals, non-ferrous metals offer a significant advantage in terms of corrosion and rust resistance due to the absence of iron. As a result, these materials are suitable for highly corrosive situations, such as liquid, chemical, and wastewater pipelines. Non-ferrous metals can be used in a wide range of electrical and electronic applications, as they are also non-magnetic. Non-ferrous metals such as copper, zinc, aluminum, lead, nickel, cobalt, chromium, gold, silver, and many others are frequently used in m...

Ferrous metals are metals whose main element is iron, such as stainless steel. They are known for their mechanical properties, such as high tensile strength. They are also magnetic and can be easily shaped or formed. Carbon steel, stainless steel, cast iron, and wrought iron are common examples of ferrous metals. Because of their strength and durability, ferrous metals are widely used in the construction, automotive, and manufacturing industries, and are suitable for architectural and structural uses such as skyscrapers, bridges, and railroads. Ferrous metals also have magnetic properties. However, due to their high carbon content, many ferrous metals tend to rust. The exceptions are stainless steel, which does not rust due to chromium, and wrought iron, which does not rust due to its high pure iron content. Chromium forms a passive oxide layer that increases the corrosion resis...

Abrasives have played an important role in the metallurgical industry since the Stone Age, when grit was used to grind, flatten, and polish. For centuries, animal skins were used to sharpen knives and swords. Natural abrasives include emery, garnet, walnut shells, and even talcum powder. Nowadays, most industrial abrasives are taken from ores that have been refined, hardened, and purified to optimize grinding characteristics. We have listed all the abrasives here to make it easy for you to choose the right metal sanding belts.   TYPES OF SANDING BELT ABRASIVE GRAINS   Aluminum Oxide Aluminum oxide is a naturally occurring mineral that is refined through a refractory process and is a strong, hard, irregularly shaped abrasive. Various grades of alumina can be obtained through the refractory process, the most common being brown, pink, and...

Sand planting process is divided into electrostatic sand planting and gravity sand planting. Electrostatic sand planting relies on the electrostatic field force to suck up the sand grains. The advantage is that the grains are more evenly distributed, while the disadvantage is that if the grains are too large, they cannot be sucked up. The larger the grit, the more the electric field force has to be increased, which means that the voltage and current have to be increased, thus increasing the production costs. In gravity sand planting, the grains are poured down by gravity from the top to the bottom. The advantage is that the size of the grit is not limited and the production cost is low. The disadvantage is that the grains are not evenly distributed, which results in a less strong bond and less sharp grinding than with electrostatic sand planting....

If you don't know what size belt you need, how do you get an accurate measurement? Start by looking for the product manual, which should indicate the correct belt size. If you can't find it, here are some practical tips on how to measure an abrasive belt accurately, so you know what size you need in the future.   METHOD 1: DOUBLE MEASUREMENT METHOD If your belt is smaller, press it flat against a hard surface and measure it from end to end using a tape measure or string. Double the length and you'll have a good idea of the belt size you need. METHOD 2: CUT AND MEASURE If you have an old belt, cut it into a long strip, lay it flat and measure the total length. This technique works with belts of all sizes. METHOD 3: THE STRING METHOD Take a piece of string and wrap it around the sander in the same way yo...

Some Tips For Best Polishing Results Don't rush and, each time you apply polishing paste to the disc, make sure you don't overdo it. Be gentle. As you're just finishing the piece, you don't need to apply a lot of pressure. The lines should be tight and as close together as possible. To achieve an even finish, avoid overlaps and always follow the grain of the wood. Go over the piece quickly. Avoid lingering too long on the surface. Keep plenty of clean polishing cloths and discs on hand so that you can replace them whenever you change products. When using different abrasives, it is extremely important to avoid cross-contamination. Before moving on to the next step, check the workpiece for scratches or imperfections.   Natural Polishing Solutions If you prefer to use natural materials and your stainless steel surfaces have only minor scratches, you can apply the fo...
