Different types of aluminum alloy wheels
Technically speaking, an alloy is a mixture of metals and other elements. Different combinations produce different alloys with different characteristics. These characteristics give each look and feel different, as well as changes in performance and elasticity to the element. Generally, alloys are stronger and more elastic than pure metals, which is why people choose alloys to be exposed to the elements and cause wear.
The most popular alloys are made of magnesium or aluminum. Aluminum or magnesium alloy is lighter than pure metal, but the strength is the same. They also look much better. Steel is an alloy of iron and carbon and is the most commonly used material in wheel manufacturing. However, the term "aluminum alloy wheels" is used for wheels made of non-ferrous alloys (which do not contain iron). Therefore, when you hear the term "alloy wheel", it is most likely a wheel made of aluminum or magnesium.
Magnetic wheel"-the classic appearance of magnesium alloy
The original "magnetic wheels" were made of magnesium and were originally used in racing cars. Then, throughout the 1960s, they became very popular in standard production cars. In fact, if you are looking at a classic car, it may even have pure magnesium wheels. Unfortunately, pure magnesium is not ideal for wheels-it is prone to pits, cracks, and is more susceptible to corrosion.
Fortunately, it took a short time for engineers to start developing other alloy types, and at that time aluminum became more and more popular. Therefore, the term "magnetic wheel" is widely used to refer to any die-cast wheel made of any modern material (see below), including aluminum alloy wheels up to bicycles, wheelchairs, roller skates and skateboards.
Low pressure die casting
Die casting is a manufacturing process in which metal melts at high temperatures. Then, the metal is sealed under low pressure, and pressurized air or "mixed gas" presses the molten metal into the mold or "mold" along the straw-shaped filling tube.
There, the metal solidifies into a new form, and you have an alloy wheel. When done correctly, low pressure die casting produces better results than standard cast alloy wheels.
High pressure die casting
The process is very similar to the low pressure die casting process. The mold is arranged in a large machine with high closing force. This forces the mold to close. The molten magnesium is poured into the filling tube (in this case, called the filling sleeve). The piston then pushes the metal into the mold very quickly under high pressure. After the magnesium is cured, open the mold and you will have a brand new magnesium die-casting wheel.
This method is much more economical than other methods, and reduces the price for consumers without affecting the corrosion resistance. However, they have low ductility and are not as strong as low-pressure die-cast wheels.
However, no matter what the wheels, they can be repaired. Need to remove dirt and other particles, and then peel the paint to the bare alloy. If you cause damage to the curb, a professional wheel repair machine will be used to eliminate the surface trauma. Sanding equipment can also be used for minor damage, and most garages are not available. Finally, use the powder coating, varnish or paint system to start the re coating process of the grinding wheel.
If you are the proud owner of diamond cut alloys, you may find it difficult to distinguish them from painted wheels-but they can be distinguished by their two-tone appearance. They have a darker inner layer and a silver outer layer, and the painted wheels will be a color and tone. To perform diamond cut alloy renovation, you need a dedicated lathe to reduce the surface of the wheel to remove the damage, and then several coats of paint will be applied to match the original color.
