What is the features of CNC machined aluminum metal ...

Aluminum is the most widely used and widely used metal material among non-ferrous metals, and its application range is still expanding. There are many kinds of aluminum products produced using aluminum, and there are more than 700,000 types according to statistics. Various industries such as construction and decoration, transportation, and aerospace have different needs.

   I.          The advantages and characteristics of aluminum are as follows:

1.     Low density. The density of aluminum is about 2.7g/cm3. Its density is only 1/3 of that of iron or copper.

2.     High plasticity. Aluminum has good ductility and can be made into various products through pressure processing methods such as extrusion and stretching.

3.     Corrosion resistance. Aluminum is a highly negatively charged metal. A protective oxide film will be formed on the surface under natural conditions or anodic oxidation, which has much better corrosion resistance than steel.

4.     Easy to strengthen. The strength of pure aluminum is not high, but its strength can be improved after anodizing.

5.     Easy surface treatment. Surface treatment can further improve or change the surface properties of aluminum. The aluminum anodizing process is quite mature and stable in operation and has been widely used in the processing of aluminum products.

6.     Good electrical conductivity and easy to recycle.

Because of the special characteristics of aluminum, no matter what kind of processing machine is used, the tool is often not satisfactory in terms of efficiency and lifetime of the aluminum production industry. The characteristics of aluminum are as follows: Compared with steel and high-temperature alloys, it is a soft metal. The hardness of HRC is not high, but it is more tough. Therefore, the relative requirements of the tool are relatively higher. If the soft metal is cut with a high-hardness tungsten steel milling cutter, the cutting edge will be broken, and the tool life will be very short. It requires high-quality tools with low hardness and no sticking to the knife to complete the processing. The only way the knife can increase the machine's speed and efficiency can be.

 II.          Method to reduce deformation of aluminum processing.

1.     If there are multiple cavities on the plate part, it is not advisable to use the sequential processing method of one cavity one cavity during processing, which will easily cause uneven stress and deformation of the parts. Multi-layer processing is adopted, and each layer is processed to all cavities at the same time as much as possible, and then the next layer is processed to make the parts evenly stressed and reduce deformation.

2.     The deformation of thin-walled workpieces due to clamping during processing is difficult to avoid even for finishing. In order to reduce the deformation of the workpiece to the minimum, you can loosen the pressing piece before the finishing process reaches the final size, so that the workpiece can be restored to its original shape freely, and then slightly tighten it, whichever is the only way to clamp the workpiece (completely According to the feel), the ideal processing effect can be obtained in this way. In short, the point of action of the clamping force is best on the supporting surface, and the clamping force should act in the direction of good rigidity of the workpiece. Under the premise of ensuring that the workpiece does not loosen, the smaller the clamping force, the better.

3.     When machining parts with cavities, try not to let the milling cutter plunge directly into the part like a drill bit, resulting in insufficient chip holding space of the milling cutter, unsmooth chip removal, and overheating, expansion and collapse of the part. Unfavorable phenomena such as knives and broken knives. First, drill the hole with a drill of the same size as the milling cutter or one size larger, and then mill it with the milling cutter. Alternatively, the CAM software can be used to produce the spiral cutting program.

Aluminum foil tape is a type of adhesive tape that uses a thin layer of aluminum foil as its backing material. The tapes is commonly used in construction and HVAC (heating, ventilation, and air conditioning) systems to seal joints and seams, as well as to insulate pipes and ductwork.

Advantages of Aluminum foil tape:

1. Thermal Insulation

Aluminum foil tape is an excellent thermal insulator. It reflects heat and cold, making it suitable for applications where temperature control is crucial, such as HVAC (Heating, Ventilation, and Air Conditioning) systems. It helps to maintain a consistent temperature by preventing thermal transfer.

2. Moisture and Vapor Barrier

Aluminum foil tape has high moisture and vapor resistance. It acts as a barrier against moisture, preventing it from seeping through joints or seams. This makes it ideal for sealing HVAC ducts, pipes, and other applications requiring moisture protection.

3. Fire Resistance

Aluminum foil tape is fire-resistant, making it a safe choice for applications where fire protection is important. It can withstand high temperatures without burning or releasing toxic gases, making it suitable for fireproofing and insulation purposes.

4. Reflectivity

The shiny surface of aluminum foil tape reflects light and heat effectively. It can be used to enhance the reflectivity of surfaces, such as in grow rooms or greenhouses, where it helps redirect light onto plants. Additionally, it can be used in photography or lighting setups to control light reflection.

5. Easy Application

Aluminum foil tape is flexible and easy to work with. It can conform to irregular shapes and surfaces, allowing for easy installation even in hard-to-reach areas. The adhesive backing makes it simple to apply, and it adheres well to various materials, including metal.

6. Wide application

Aluminum foil tape has many uses including sealing ducts for heating, air conditioning and refrigeration, vapour barrier, sealing and masking of aircraft, masking in powder coating applications.

7. High Durability and Versatility

Foil tapes are manufactured using superior materials for its outstanding adhesion and cohesion as well as its thermal properties. It is also highly flexible and can even be used in uneven surfaces &#; making it a great option for harnesses, wires and exhaust pipes. Foil tapes are also easy to apply &#; sticking almost instantly. The same goes when peeling it.

8. Good aging resistance and longevity

Aluminum foil tapes also have high mechanical strength, aging resistance, and they perform very well under UV light. They have high durability and longevity compared to most tapes. 

DeYou Tape is one of the largest HVAC aluminum foil tape manufacturer, DeYou tapes products include Aluminum foil tape, FSK tape, Aluminum foil glass cloth tape, Foil scrim tape, PET laminated foil tape.

Key features of our aluminum foil tapes:

1. UL 723 rated and meets International Building Code standards

UL 723 is a test to measure the surface burning properties of building materials. To meet the International Building Code&#;s definition of fire-resistant, a composite material must have a flame spread rating no higher than 50. DeYou Tape&#;s foil tapes are UL723 certified, which is worth noting because not all cloth-backed duct tapes or foil tapes are UL 723 rated.

2. Extreme cold and heat temperature versatility

The cold-temperature aluminum tape can be used to protect metal-backed insulation. This type of tape is also useful for sealing joints and seams in fiberglass and aluminum-backed duct board. DeYou tape&#;s all-weather aluminum foil tape is coated with a superior performance flame-retardant solvent acrylic adhesive, working equally well in extreme hot and cold weather conditions.
