    Considerations when choosing between bar and plate aluminum What should you consider before purchasing a material? Both bar and plate are highly machinable. They also have similar strength-to-weight ratios. But the following different aspects may affect the success of your project.   Edge conditions Bars are cut at the end only, usually with a band saw. The natural corners of square bar stock will have a small radius during extrusion and a linear grain on the side of the part perpendicular to the cut edge. The sheet can be cut to shape using a waterjet or band saw cut at all vertical edges. There are at least two parallel faces in the sheet that will not be touched. These are usually the top and bottom sides of the blank. When ordering material, it is important to consider stock tolerances for both natural and cut edges and to add enough material to properly machine the finished part.   Size Ranges Material dimensions affect the size of custom parts and the avail...

There are countless options when selecting metal stock for professional-level CNC machining jobs , but the size, shape and grade of that stock will affect the end result. Professionals and hobbyists alike must understand these details in order to select the right material for their custom parts. Let's say you are sourcing raw materials to make a custom part. You are interested in 6061 aluminum. Aluminum 6061-T6 is one of the most common materials used in small batch manufacturing. It is used in many industries - aerospace, construction, etc. At Liangyin, you have nearly a dozen options for shapes, sizes, and cuts of this material. Bar and plate are the most common choices, and understanding the differences is a good place to start your next project.   Considerations when choosing between bar and plate aluminum What should you consider before purchasing a material? Both bar and plate are highly machinable. They also have similar strength-to-weight ratios. But the following diff...

CNC machining is a traditional manufacturing process that uses a drill and turning tool to create parts by removing material from a solid block of material. The process is fast, repeatable and ideal for making parts with tight tolerances. CNC machining can be done with any material rigid enough - from plastic to metal to fiberglass - and aluminum is a popular choice among product teams.   Aluminum Grade Selection The first step in starting your CNC aluminum machining project is choosing the right metal alloy. Each grade has its own unique set of properties and characteristics, depending on your needs. When examining the properties of aluminum, you need to consider strength, electrical conductivity, corrosion resistance, or a combination of all of these. Two of the most common aluminum metals used in industry are 6061 and 7075 aluminum alloys. So, what is the difference between the two?   6061 Aluminum Properties 6061 is a common aluminum alloy produced through a heat treatment...

Whether you’re designing computers, LED lighting, or other electronics, you need to think about heat sinks. Heat sinks absorb and dissipate the heat from these devices, helping to keep them cool. Today we’ll talk about some different types of heat sinks, how they’re made, and their applications. Generally, heat sinks are grouped by the manufacturing process used to create them, i.e. extruded, machined, etc. We will discuss 6 below. But, first, it’s important to understand that all heat sinks fall into two categories. The Two Major Heat Sink Categories All heat sinks can be broken down into two major categories… active and passive. What is the difference between active and passive heat sinks? Active Heat Sinks These generally have a fan or blower of some kind. The most common type is a ball bearing motor fan. These provide excellent performance, but they consist of moving parts and are on the expensive side. Passive Heat Sinks These have no mechanical components. They only use the conve...

Custom aluminum heatsink for LED with CNC machining in Foshan Factory Product Description The main function is to continuously export the heat generated by the LED chip to the environment, so that the temperature of the chip remains within the required range, so as to ensure that the LED lamp can operate normally.The quality of the radiator mainly depends on the thermal resistance of the radiator, the smaller the thermal resistance, the lower the LED lamp temperature under the same conditions, the lower the LED temperature, the longer the service life of the chip will be.The heat resistance of the radiator shall include heat conductivity heat resistance and heat dissipation heat resistance.

Brief Introduction of Extruded Aluminum Heatsink in LED Lamp Compared with traditional lights, LED (Light Emitting Diode) lamps have the advantages of long service life, energy saving, and high light efficiency. In recent years, LED lights are increasingly used in various industries, such as street lamps, industrial and mining lamps, landscape lamps, indoor lighting, etc. However, the LED lamp also has certain disadvantages. For example, its calorific value is very high, and when the temperature rises to a certain degree, it will affect the lifespan and luminous effect. In practice, LED light conversion efficiency is about 30%. The remaining 70% will be released as heat. LED heat rise has a direct impact on luminous efficiency, main wavelength instability, low chromatic aberration. Therefore, for a good LED lights, the first to consider is the heat dissipation problem, the choice or design of a good heat sink is crucial. LED extruded aluminum heatsink To do a good job of the LED light ...

    1. Light weight: Aluminum is about 1/3 the weight of sand-cast or die-cast aluminum, making aluminum extrusions easier to handle. 2. Reflective: The surface can be polished or brushed to produce reflective or matching components, making aluminum extrusions attractive. 3. Flexibility: Aluminum combines strength and flexibility to bend under load or spring back from impact, leading to the use of extruded components in automotive crash management systems. 4. Corrosion resistance: Aluminum extrusions have excellent corrosion resistance. They do not rust and the aluminum surface is protected by its own natural oxides. A protection that can be enhanced by a powder coating. 5. Strong: Aluminum profiles can be made as strong as needed for most applications, and due to the nature of the extrusion process, strength can be concentrated where it is really needed by including different wall thicknesses and internal reinforcement in the profile design. Extrusions are particularly well s...
